Precautions:
To avoid instrument damage and potential dangerous accident; do not use this product before reading
the manual.
Introduction:
This sensor/controller detects generally used refrigerant gases within Australia (R22, R123, R134a, R404,
R407, R410 etc) within the range 0-1000ppm via diffusion. Each sensor is factory calibrated to a specific
gas type and output type and range. It has an analog output which can be one of the following, 4-20mA;
0-20mA; 0-5V; 0-10V. There is also a volt free relay which can be user programmed to operate anywhere
within the sensor range. The unit is powered and calibrated to 24VDC.
Specifications:
