The Model C is a non-calibrated detector used primarily for arson investigation and where it is desirable to detect trace amounts of hydrocarbons.
Turn unit ON, allow several minutes for warm up, and then scan area of concern. When gas or a hydrocarbon is present, beep tones in synchronism with a red indicator light will occur. A slow beep
rate indicates a small amount of gas or accelerant, whereas a more rapid rate indicates a higher gas
concentration. A mute switch is provided to silence the audio tones and an electronic purge permits rapid recovery of the sensor.
Detects approximately 125 toxic/combustible gases and/or vapors; including all heating gases.
