2 Introduction
The Fluke Hart Scientific 9133 Mid-Range Field IR Calibrator may be used as
a portable instrument or bench top temperature calibrator for calibrating
point IR thermometers. The 9133 is small enough to use in the field, and
accurate enough to use in the lab. Calibrations may be done over a range of
-30°Cto150°C(-22°F to 302°F). Temperature display and setability resolu
-
tion of the 9133 is 0.1 degrees.
The instrument features:
•
Rapid heating and cooling
•
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 precision platinum RTD as a sensor and controls the well
temperature with a FET driven thermal electric device.
For improved uncertainties, a 0.125" diameter external reference thermome-
ter may be used in the calibration probe hole at the top of the instrument.
When using an external reference thermometer, the instrument accuracy,
stability, and ambient temperature effects on the surface can be minimized.
The LED front panel continuously shows the current temperature. The tem-
perature may be easily set with the control buttons to any desired tempera
-
ture within the specified range. The instrument’s multiple fault protection
devices insure user and instrument safety and protection.
The 9133 calibrator was designed for portability, low cost, and ease of oper
-
ation. 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 de
-
scribed in this user guide.
