GTD-2000Tx transmitter and local display type gas detectors for toxic gases and oxygen are available for purchase from Gas Detection Australia . These detectors have a flame proof structure which means that they can be used in explosion hazardous areas.
These devices display excellent selectivity because they can adapt their detection principles for only toxic gases and oxygen. They are capable of continuous detection of toxic gases and oxygen and have a self diagnosis function that incorporates a built-in microprocessor. They are also extremely reliable and able to detect toxic gases below TLV.
Their design includes a built-in back lit LCD display, auto calibration and program setting with a magnetic bar and a 4-20mA DC output signal. These gas detectors also come in two different models; remote and duct mount.
