FLUKE Calibration 9009 Dual-Well Dry-Well
Two blocks. One portable calibrator. Full temperature coverage.
Dual Independent Temperature Blocks
The Fluke Calibration 9009 combines two independently controlled temperature blocks into one compact, rugged system:
- Hot block range: 50 °C to 350 °C
- Cold block range: –15 °C to 110 °C
- Each block is powered by a precision Hart Scientific temperature controller—not off-the-shelf components, but industry-leading technology from the world’s top temperature calibration experts.
Flexible Multi-Probe Calibration
Each block includes two wells with removable inserts, giving you unmatched flexibility:
- Calibrate up to four probes simultaneously
- Use two probes with an external reference thermometer (e.g., Hart 1521 LLK)
- Perform quick zero/span checks for transmitter calibration with both blocks in use
Portable and Field-Ready
The 9009 is built for portability and field durability:
- Housed in a rugged Pelican™ case—airtight, watertight, and impact-resistant
- Weighs only 10 lbs (4.5 kg), compact and easy to carry
- Internal storage holds the power cord and four extra inserts
- Inserts available for sensor sizes from 1/16” (1.6 mm) to 7/16” (11.1 mm)
This system is truly ready to go wherever your work takes you.
Reliable Accuracy and Stability
Performance you expect from a Fluke/Hart Scientific source:
Block Display Accuracy Stability Cold ±0.2 °C ±0.05 °C Hot ±0.6 °C ±0.05 °C NIST-traceable calibration certificate included for both blocks.
PC Connectivity and Automation
- RS-232 interface included for temperature monitoring and control via PC
- Fully compatible with MET/TEMP II software for automated calibration of RTDs, thermocouples, and thermistors
The Complete Field Calibration Package
With the Fluke 9009 Dual-Well Dry-Well, you get:
- Two independent blocks
- Full temperature coverage from –15 °C to 350 °C
- True field portability in a compact, durable case
- Flexibility for multiple sensors and calibration modes
- Built-in automation and PC integration

Intrinsically Safe
FLUKE 1551A/1552A Intrinsically Safe Thermometers
Product overview: Fluke 1551A/1552A Intrinsically Safe Thermometers
The Fluke 1551A “Stik” Thermometer provides a temperature range—50 °C to 160 °C (-58 °F to 320 °F). The Fluke 1551A delivers repeatable temperature measurements accurate to ±0.05°C over its full range. It is rated intrinsically safe for working in indoor or outdoor environments where potentially explosive gases may be present. It’s a great choice for environments that aren’t potential explosive as well such as the floor of a processing plant. The battery operated, portable reference thermometer is a great choice for daily checks of working thermometers, custody transfer temperature determination, PET calibration, LIG calibration, and temperature transmitter calibration and verification.
The stainless steel probe and digital readout are fixed together and calibrated as a system. The large backlit LCD display rotates 90° degrees making it easy to read from any angle. And a user-configurable stability/trend indicator lets you know when your temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to up to 300 hours. And the low-battery indicator and stop-measure function prevents erroneous measurements from being made due to a low battery. Plus you can easily and accurately calibrate the 1551A with a simple three-point calibration function.
Other useful features:
- Delivers 300-hour battery life
- Shows percent battery-life and low-battery indicators
- Includes NVLAP-accreditation and NIST-traceable calibration

Temperature Calibrators
FLUKE 9190A Ultra-Cool Field Metrology Well
Ideal for cleanroom environments and demanding calibration work
Cleanroom-Compatible, Ultra-Portable, and Fast
Traditional calibration baths are known for stability and uniformity—but they’re far from ideal for cleanroom use. Their large size, fluid handling requirements, and potential for spills or vapors make them a poor fit for controlled environments.
The Fluke 9190A Ultra-Cool Field Metrology Well offers a smarter solution. Designed specifically for cleanrooms and critical process industries, it provides:
- Wide temperature range suitable for pharmaceutical, biomedical, and food processing needs
- Compact, lightweight design for easy transport and field use
- No heat transfer fluids, keeping your environment contaminant-free
- Faster heating and cooling times than traditional calibration baths—so you complete calibrations faster
Precision You Can Trust for Process Accuracy
Accurate process measurements are essential for quality control. Inaccurate data can lead to product recalls, regulatory penalties, lost profits, and reputational damage. That’s why your calibration equipment needs to be just as dependable as your measurement systems.
The 9190A Ultra-Cool Field Metrology Well delivers:
- Best-in-class accuracy, stability, and uniformity
- Designed using decades of Fluke dry-block technology expertise
- Conformance to EURAMET cg-13 best practices for temperature block calibrators
- Thoroughly tested specs for axial and radial uniformity, hysteresis, and loading effects
Make Every Measurement Count
When you use the 9190A, you’re choosing the most accurate and stable ultra-cool dry-block calibrator available. That confidence translates into better product quality, more efficient compliance, and measurable business impact.
