Product overview: Fluke 9132/9133 Portable Infrared Calibrator with Blackbody Source

Great for clean room environments

Calibration baths are the most stable and uniform temperature sources available, but they aren’t a good fit for clean rooms. The size of a bath limits its portability, and bath fluids can easily spill and give off vapors. The 9190A Ultra-Cool Field Metrology Well is a great alternative. Its wide temperature range brackets the coldest and highest temperature ranges required for pharmaceutical, biomedical and food processing applications. The 9190A is small and lightweight, making it easy to transport. And since it does not use heat transfer fluids, clean rooms stay clean. The 9190A cooling and heating times are faster than a calibration bath—that means calibration work gets done more quickly.

An accurate temperature source is critical for dependable process measurements

Unreliable process measurements can have a damaging impact on business, leading to poor product quality, recalls, fines, waste, and lost profits. Ultimately, measurements are only as good as the temperature sources used to calibrate the measurement equipment. The 9190A Ultra-Cool Field Metrology Well incorporates the best technology and design expertise gained from decades of dry-block development experience. The 9190A conforms with EURAMET cg-13 guidelines for best measurement practices for temperature block calibrators. As a result, you can be assured that the 9190A specifications for accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis have been thoroughly and carefully defined and tested. With a 9190A Ultra-Cool Field Metrology Well, you can be confident you’re using the most accurate and stable ultra-cool dry-block calibrator available. And that will have a positive impact on your business.

Make accurate, consistent measurements… anywhere.

You need accuracy for compliance, product yields, energy savings, and consistent results. The 1524 uses current reversal, a technique used in high-end instruments that eliminates thermal EMFs, for precision temperature measurements. Specifications are guaranteed from -10 °C to 60 °C ambient. Special precision resistors and a highly stable reference voltage source keep 1524 accuracy virtually insensitive to environmental temperature.

Like all Fluke handheld tools, the 1524 Reference Thermometers endure rigorous testing in temperature extremes and under harsh conditions of vibration, so you can take them anywhere you need to go.

An optional magnetic hanger allows you to hang the thermometer for easy viewing while freeing your hands to focus on the job.

INFO-CON connectors ensure correct temperature conversion

Inside the INFO-CON, a memory chip keeps calibration information for the attached probe. Simply plugging in the probe uploads the information to the readout, ensuring the correct temperature conversion for accurate, hassle-free measurements.

Probes may be locked by password to specific channels and readouts for security or for system calibration traceability. Plug any thermocouple with mini-thermocouple jacks into an optional universal thermocouple adapter for convenient measurement. Each thermocouple adapter or standard connector supports reference junction compensation (RJC) with its own internal precision thermistor.

Monitor trends in the lab or in the field

See trends graphically on the 1524 thermometer’s 128×64-backlit LCD display. You can change the graph’s resolution at the touch of a button. Now it’s easy to see when the temperature is stable, without statistics or long delays, or monitor processes over time to verify correct operation.

Document on demand up to 25 readings and associated statistics for easy retrieval. You can view the data through the display or by uploading it to a PC via RS-232 connection and 9940 software, included free. To monitor and log more data over time, use a PC and optional LogWare II software.

RS-232-to-USB adapters are available for those who prefer USB connectors. Battery power lasts at least 20 hours on three AA batteries, or use the dc power adapter for extended periods of measurement. Power saving features can be enabled or disabled for longer battery life or greater convenience.

Applications

The new 1524 Reference Thermometers help you do twice the work in half the time. Two channels and three sensor types and high-speed measurement make you more productive and make model 1524 the one reference thermometer you need to own. It has all the features of the 1523, and it’s a data logger too. A real-time clock and memory for 15,000 time and date stamped measurements mean everything you are going to need is in this package. Log up to three times per second, or once every hour or other options in between. Download the data to a PC for analysis when you need it.

Calibration, loop checking, plant startup, troubleshooting, maintenance, and repair are some of the varied duties that need a 1524 thermometer. Use it for a handy temperature reference in baths, dry-block calibrators, thermowells, clean rooms, engines, heat exchangers, furnaces, freezers, or anything else that must be calibrated, checked, or maintained.

Accuracy

The standard-accuracy sensor (“S” model) reads temperature to ±0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ±2% RH from 20% RH to 70% RH.

All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.

Ethernet and wireless capability

With its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using Log Ware III client-server software. Ethernet also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you’re away.

Cables running along the floor can be a safety hazard, and cables hanging from the ceiling and walls are an eyesore. With the DewK, simply connect your computer through an RF modem up to 100 ft away, without the clutter of all the extra cables.

If you need a printout, send data to a printer through the RS-232 interface in real time.

Math and statistical functions

In addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity. Min, max, and a variety of other statistics are also calculated and can be shown on-screen. Daily summary statistics, including min, max, and maximum rates of change are stored for the most recent sixty days.

Calibrated sensors

With inputs for two sensors, each measuring both temperature and relative humidity, one DewK can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK.

Each sensor is calibrated for both temperature and humidity by Fluke Calibration. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different DewKs, and the recalibration of sensors doesn’t require an accompanying DewK.

Sensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available directly from your local Fluke Calibration sales representative, or directly from Fluke Calibration. Spare sensors may also be purchased from Fluke Calibration as a kit, which includes a case for the sensor, a wall mounting bracket, and a 25-foot extension cable.

Memory

The DewK has enough on-board memory to store up to 400,000 date- and times stamped data points. That’s two years’ worth of data for both measurements from two sensors if readings are taken every ten minutes!

Alarms and battery backup

Alarm settings can be set up quickly in the DewK based on temperature, the rate of change in temperature, RH, the rate of change in RH, and instrument fault conditions. Alarms can be both visual (flashing display) and audible (beeping). Likewise, alarm settings can be set up and events triggered in Log Ware III. The DewK is also equipped with a 0 to 12 volt alarm output that can trigger a process control system.

A backup battery shuts down the DewK’s display but maintains measurements for up to 16 hours in the event of a power failure.

Large, easy-to-read display

Want to view data from across the room? Want to view data from two temperature and two humidity inputs simultaneously? Want to view data graphically, statistically, or both? At the same time?! The DewK does everything you could want—or at least everything we could think of. Up to sixteen different display setups can be stored and recalled at the touch of a single button. And all 16 can be easily modified, so you get exactly what you want.
