MultiTox MOS Gas detector

This high-spec H2S detector uses a semiconductor sensor that overcomes most of the problems associated with this technology. The MultiTox DM-TT6 has higher reliability and lower maintenance. In other words: Increased safety and reduced cost. 

Gas detectors - MultiTox MOS Gas detector

Features

Performance

The MultiTox DM-TT6 detector has a thin layer semi-conductor-type sensor, resulting in fast response and high accuracy, as well as low interferences with other gases.
Environment compensation Modern electronics provides compensation for humidity and temperature changes.

1-year calibration interval

When other semiconductors on the market has to be exposed to gas every month to avoid the sensor to fall asleep, the Simtronics semiconductor sensor needs yearly calibration test only.

Easy maintenance
  • The interchangeable and removable cartridge make this detector particularly easy to maintain.
  • Remote control All controls, configurations and readouts are remotely accessible from the infrared remote controller.
An autonomous sensor

The digital processing linearises the measurement signal before transmitting it to a gas detection unit or plant automatic control system. Detectors have both analog and contact outputs.

Application

Offshore platforms, Refineries, Chemical industry
