1 Introduction

Hart Scientific’s Model 9100 HDRC Dry-well Calibrator is a small, portable in-

strument designed for quick on-site checks and calibration of thermocouple

and RTD temperature probes. It features an aluminum temperature block well.

Three different blocks are available. Block “A” has six holes, four that accept

probe diameters of 1/4", 5/32", 1/8", and 1/16", and two that accept probes of

3/16" diameter to allow comparison calibrations. Block “B” has four holes that

accept probe diameters of 3/8", 1/4", 3/16" and 1/8". Block “C” has two holes

that accept probe diameters of 3/16" and 1/2". See Figure 1 on page 3. The in-

strument is controlled by a microprocessor based digital PID temperature con-

troller and uses a precision platinum RTD as a sensor with a heater to control

the well temperature. The controller display will show the well temperature and

also the set-point temperature. The temperature may be set to any tempera-

ture within the range of the instrument in 0.1 degree increments by using the

three buttons on the control panel. The calibrator’s multiple fault protection de-

vices insure user and instrument safety and protection.

The 9100 dry-well calibrator was designed for portability, speed, and ease of

operation. It’s use will provide a means of quick, accurate calibration and com-

parisons of temperature sensors and other devices.
