The ST650EX is an all-round gas detector which functions well under the most difficult circumstances. The heart of the detector is a replaceable gas sensor. This sensor is available in various versions, such as a catalytic flammable gas sensor, Infrared (NDIR) and a Thermal Conductivity sensor (TCD).

The sensor has a long life-span, which achieves an optimal cost of ownership. The ST650EX is available with or without a graphic display. The version with a graphic display, shows the measured value and various status notifications locally.

The capacitive key control gives you an experience similar to a touchscreen and enables easy navigation through the user/calibration menu.

The user menu is secured with a password; unauthorized users cannot access the gas detector. The control of the user/calibration menu does not require additional tools (for example magnets). Simple, easy and user friendly!
