DG-1
DIGITAL GAS DETECTORS
dg1_e 04/06
The DG-1 microprocessor-based digital gas detectors are characterized by reliability
and low current consumption. Due to a digital temperature compensation feature they
can operate within a wide temperature range. Gas concentration above the threshold
level triggers visual and audible alarm signals. The detectors can be used as part of
a security system, or as a stand-alone device.
The DG-1 series of digital gas detectors includes the following products:
DG-1 CO - carbon monoxide detector;
DG-1 LPG - propane-butane gas detector;
DG-1 ME - natural gas (methane) detector;
DG-1 TCM - soporific gas detector (e.g. chloroform vapors).

electronics board of DG-1 TCM detector differs in size and shape of the gas sensor
installed.
