2 Introduction
The Hart Scientific Model 9105/9107 dry-well calibrator may be used as a por-
table instrument for calibration of temperature probes. The 9105 operates over
the range of –25°C and 140°C. The 9107 operates over the range of –45°C to
140°C.
These dry-well calibrators feature an interchangeable aluminum probe sleeve
along with 4 fixed wells. The temperature is accurately controlled by Hart's
precision temperature controller.
The calibrator controller uses a precision platinum RTD as a sensor and con-
trols the well temperature with thermoelectric modules. The LED front panel
display continuously shows the current well temperature. The temperature may
be easily set with the control buttons to any desired temperature within the
specified range.
The 9105/9107 dry-well calibrator was designed for portability, moderate cost,
and ease of operation. With proper use the instrument should provide continued
accurate calibration of temperature sensors and devices. The user should be fa-
miliar with the safety guidelines and operating procedures of the calibrator as
described in the User’s Guide.
