|Our very stable TCD has a sealed reference to minimize maintenance.||19'' rack mount or NEMA 4 wall mount.||The two point calibration for the TCD uses a zero gas and a span gas. It is initiated by a push button switch. The time to calibrate is about 1 minute. The FID requires zero air and span gas for calibration. In the 204, the calibration valves are built into the Analyzer. The remote calibration can be activated by a PLC controlled contact closure.||Our 2 line by 16 character display is backlit. The upper display provides the concentration and the bottom display provides the sensor, units, alarm and logging mode. For multisensor units, a 3 readout LED is used.|
