The MultiTox DG-TT7-S is a solid state (MOS) based smart gas detector for the detection of Hydrogen Sulphide. The device has been designed to withstand harsh environment and provide easy operation The unit is fully configurable using a wireless hand-held terminal TLU, using a magnet or by using HART protocol option. The configuration of the outputs is adjustable using the TLU or the magnet that can be used in areas classified as potentially explosive. The MultiTox DG-TT7-S is SIL2 certified, 3 on board relays in option, plug and play sensors and a high visible display that changes colour depending on the status mode. The unit may be interfaced directly with a wide range of centrals and PLC’s. The device supports HART 7 protocol option for full configuration and diagnostics over non-proprietary interface. This new version also offers automatic calibration, TELECAPTEUR Calibration Management Software. It allows loading, comparison and logging of the last calibrations carried out and this can be done by one person only.
