The DIGITAL Model 100 TC is a
Digital Vacuum Instrument intended for laboratory, industrial refrigeration, and
scientific use. The 100 TC senses vacuum by measuring the temperature rise of an
electrically heated fine-wire sensor exposed to a vacuum. Its digital display reads vacuum
in one micron increments from 1 to 1999 micron. The 100 TC offers grater speed and better
resolution and readability than analog (pointer) meter instruments presently in
use. Because all linearization and temperature compensation are done electronically, no
user calibration or adjustment is ever necessary. The rugged ABS plastic case and absence
of moving parts make the 100 TC rugged enough to stand up to years of punishment in
refrigeration field service use and other similar applications.
The 100 TC's state of the art design includes a precision band-gap
voltage reference, constant current filament excitation, CMOS devices, a liquid crystal
display, a precision low drift amplifier, and an industry standard interchangeable vacuum
Because of its resolution, and fast response, the 100 TC is well suited
for trouble shooting. The effect of small changes can be seen virtually instantaneously,
and the readings are inherently free of parallax.
The instrument can be fitted with controller outputs and multi-probe
switching. Consult factory for details.
The 100 TC is supplied with an AC wall adapter, probe cable, and a
Hastings Gauge Tube Sensor.
