Overview
About D12 Toxic & Combustible Gas Detector
The D12 uses electrochemical sensors for toxic gases and oxygen and catalytic bead sensors for combustible gases. The self-aligning sensor holder plugs in, with automatic sensor recognition and verification when contact is made.
Four configurations are available: loop-powered transmitter, loop-powered with HART, transmitter with integral relays, and transmitter with Modbus. Three concentration alarms (caution, warning, alarm) and a fault alarm are programmable, and an internal data logger records measurements.
An optional Auto-Test gas generator, depending on the sensor, checks sensor response automatically.
