Field Metrology Wells
Whether you need to calibrate
4-20 mA transmitters or a simple
thermostatic switch, a Field
Metrology Well is the right tool
for the job. With three models
covering the range of –25 °C to
660 °C, this family of Metrology
Wells calibrates a wide range of
sensor types. The optional process
version (models 914X-X-P) pro-
vides a built-in two-channel thermometer readout
that measures PRTs, RTDs, thermocouples, and
4-20 mA transmitters which includes the 24 V loop
supply to power the transmitter.
Key features:
• Lightweight, portable, and fast
• Cool to –25 °C in 15 minutes and heat to 660 °C
in 15 minutes
• Built-in two-channel readout for PRT, RTD,
thermocouple, 4-20 mA current
• True reference thermometry with accuracy to
±0.01 °C
• Automate calibration with the Fluke 754 or
Fluke 1586A or use onboard automation with
process version
Summary specifications
• 9142 –25 °C to 150 °C ± 0.2 °C Full Range
• 9143 33 °C to 350 °C ± 0.2 °C Full Range
• 9144 50 °C to 660 °C ± 0.35 °C to 420 °C
± 0.5 °C at 660 °C
Application coverage
• RTD and thermocouple calibration
• Temperature transmitter calibration
• Automated calibration
9190A
Ultra-Cool Field Metrology Well
The Fluke Calibration 9190A
Ultra-Cool Field Metrology
Well is the most accurate and
stable, cold temperature dry-
block on the market. It’s ideal
for applications that demand
strict quality control and
regulatory process compliance.
These applications include
on-location validation and
calibration of RTDs, thermocouples, thermometers,
and sensors used with process control equipment
such as medical freezers, laboratory refrigerators,
cold rooms, blood banks, sterilizers (autoclaves),
and freeze dryers.
Key features:
• Optional built-in two-channel readout for PRT,
RTC, TC, 4-20 mA and reference thermometer
• Automate calibration with the Fluke 754 or Fluke
1586A or use onboard automation with process
version
Summary specifications
• Wide temperature range from –95 °C to 140 °C
• Best-in-class stability: ± 0.015 °C full range
• Accuracy using built-in reference thermometer
readout: ± 0.05 °C full range
• Display accuracy: ± 0.2 °C full range
Application coverage
• Calibrate RTDs, PRTs, thermocouples, and
transmitters down to –95 °C
• Characterize thermocouples and RTDs for
chamber mapping
