The TQ4300 16 point sampling system is a multipoint, sequential, aspirated, gas sampling system. The system extracts a gas sample from a desired location, via transport lines to an analysing unit where the sample is monitored for ‘Freons’ and/or ‘CO2’ or flammable gases. The TQ4300 in its usual form uses fixed gas sensor heads to constantly monitor gases in conjunction with solenoids and a pump. The system is capable of detecting 2 seperate gases at the same time.
