1.1 Introduction
Fluke’s Hart Metrology Wells (9170, 9171, 9172, and 9173) are designed to be stable
heat sources that can be used in a laboratory or eld environment. With a calibrated
display and an optional built-in reference thermometer input (designated with “-R”),
Metrology Wells may also be used as a reference standard.
Metrology Wells feature interchangeable probe sleeves that t various sized diameter
probes.
The Metrology Wells’ controller uses a PRT sensor and thermoelectric modules or
heaters to achieve stable, uniform temperatures throughout the block.
The LCD display continuously shows many useful operating parameters including the
block temperature, block stability, heating and cooling status, and current set-point.
The temperature may be easily set with the control buttons to any desired temperature
within the calibrator’s specied range.
Metrology Wells are designed for laboratory performance that can be used anywhere.
With proper use, the instrument will provide continued accurate calibration of temper-
ature sensors and devices. Before use, the user should be familiar with the warnings,
cautions, and operating procedures of the calibrator as described in the Getting Started
Guide.
