DT300 is a unique instrument that is used for checking and calibration of detectors with semi conductive sensors.

A recurring concern when calibrating sensors is to know if the air is clean or contaminated. Traditionally, this has been accomplished by applying synthetic air or ”zero gas” from a bottle. DT300 features a unique design with an integrated reference sensor that makes it
possible to calibrate the relevant sensor without applying gas.

Function

The unit is equipped with a reference sensor (ordered separately)
for the relevant gas.

The reference sensor is plugged into the unit and the LCD display
indicates when the sensor is heated and ready to use.

The reference value for the gas appears in the LCD display.

The value is then used to calibrate offset-value on the relevant detector.

Alphanumeric LCD display shows:

•The integrated reference sensors offset-value

•Offset-value on the tested detector

•System voltage (+5 V)

•C-, B-and A-alarm levels

TECHNICAL DATA:

For control and calibration of
semiconductor detectors

For control and adjustment of alarm levels of monitoring units
