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 CO2. The TQ4300 in its usual form uses fixed gas sensor heads to constantly monitor gases in conjunction with solenoids and a pump. The TQ4300 sampling system is primarily designed for gas detection and plant leak detection.
