•
This detector is a fixed type gas detector head that detects leak of combustible/toxic gases and performs
the alarm activation when the gas concentration is over the setting value.

analysis/measurement for gases. Please fully understand the features of the detector before using it, so

the built-in gas sensor. The concentrations of detected gases are displayed on the seven-segment LED.

An external pump etc. outside the detector introduces gas to perform gas detection.
•
The detector has a built-in alarm contact and can be used either as a gas alarm, fault alarm, or common
