二氧化碳分析仪

302K便携式二氧化碳烟气分析仪，手提箱（WP）外壳
The Model 302 Series Portable Flue Gas Analyzers have been designed for accuracy, reliability, and ease of use and service. The 302 uses a solid state infrared detector which responds quickly to CO2 present in the flue gas sample.

In operation, a built in sample pump draws in the flue gas sample through the S.S. probe, 12 ft sample hose, condensate removal filter, secondary filter and flow meter then on to the CO2 detector. The detected CO2 is displayed on an LCD digital meter which has a switchable backlight for use in dark areas.

The 302 can optionally indicate net stack temperature (302T) for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided.

A rechargeable battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.

423A二氧化碳分析仪，控制或报警继电器触点控制CO2产生器或CO2增量系统的通断，在过程应用中触点还可能被用于报警
The Nova 423 Series Carbon Dioxide monitor/controller has a sensitive solid-state infrared CO2 detector which continuously displays detected CO2 on a front panel digital meter. A built in sample pump draws in a sample through a filter and flow meter then on to the solid state infrared detector for analysis. A 4-20mA linear output signal is available for operation of a recorder or input to a computer. The Model 423 CO2 Monitor can be time shared between a number of sample points using a Nova automatic sequencer. Calibration need only be done once per year. Applications include HVAC and IAQ systems, CO2 monitoring and control of greenhouses, wineries, breweries, food processing plants or any area requiring a stand-alone CO2 monitor or controller.

Relays for both models adjustable from 0-100% span; adjustable dead band; contact rating 5 A @ 230 VAC SPDT
