Introduction
Fluke's Hart Scientific Division Metrology Wells (9170, 9171, 9172, and 9173) are designed to be
stable heat sources that can be used in a laboratory or field 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 fit 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
specified range.
Metrology Wells are designed for laboratory performance that can be used anywhere. With proper
use, the instrument will provide continued accurate calibration of temperature 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.
