Introduction
The Hart Scientific 9132 Portable IR Calibrator may be used as a portable instrument or bench
top temperature calibrator for calibrating point IR thermometers. The 9132 is small enough to
use in the field, and accurate enough to use in the lab. Calibrations may be done over a range of
50°C to 500°C (122°F to 932°F). Temperature display and setability resolution of the 9132 is
0.1 degrees.
The instrument features:
Rapid heating and cooling
Hand strap
RS-232 interface capability
Built in programmable features include:
Temperature scan rate control
Eight set-point memory
Adjustable readout in °C or °F
The temperature is accurately controlled by Hart’s digital controller. The controller uses a preci-
sion platinum RTD as a sensor and controls the well temperature with a solid state relay (triac)
driven heater.
For improved uncertainties, a 0.125” external reference thermometer may be used in the cali-
bration probe hole at the top of the instrument. When using an external reference thermometer,
the unit accuracy, stability, and ambient temperature effects on the surface can be minimized.
The LED front panel continuously shows the current temperature. The temperature may be
easily set with the control buttons to any desired temperature within the specified range. The
instrument’s multiple fault protection devices insure user and instrument safety and protection.
The 9132 calibrator was designed for portability, low cost, and ease of operation. Through
proper use the instrument will provide continued accurate calibration of temperature sensors
and devices. The user should be familiar with the safety guidelines and operating procedures of
the calibrator as described in this user guide.
