1-4 SAMPLE REQUIREMENTS

Maximum allowable sample pressure is 690 hPa-gauge (10 psig) for a standard configuration NDIR that has a flow restrictor which sets the flow at between 0.5 L/min. to 1 L/min. Special high pressure cells (up to 10,350 hPa-gauge, 150 psig) are available. Sample temperature range is 0°C to 55°C, and maximum dewpoint is 40°C. The sample must be filtered to exclude particulates larger than 2 microns in size. Consult factory for special configurations with specifications outside of those listed above.

interference. They do not provide protection from explosion hazard. The purge gas vents into the case, which has no outlet fitting for these types of purge gases.
