Simtronics DG-TX7 is a series of gas detectors from Teledyne, supplied with a pair of OXYCOL catalytic sensors and compensated circuitry, capable of detecting a range of flammable gases, including Hydrogen. The DG-RX7 range has a Syntel output.

Designed to be used in harsh environments, as long as Oxygen is present. In the absence of O2, an alternative monitor equipped with a thermal conductivity sensor is available.

Part of the MultiTox DG7 family, all detectors have a universal platform for standardised maintenance and training.

Microprocessor-driven, configurable using a wireless hand-held terminal (TLU) or by using a hard-wired HART protocol option, providing installation options and reduced service costs. Relay operation and alarm levels can be set using the TLU, a hazardous-area-approved device.
