- The Model 302A Series Portable Gas Analyzers have been designed for accuracy, reliability, and ease of use and service. The 302A uses a solid state infrared detector which responds quickly to CO2 present in the gas sample.
- In operation, a built in sample pump draws in the gas sample through the sample hose, condensate removal filter, secondary filter and flow meter then on to the infrared CO2 detector. The detected CO2 is displayed on an LCD digital meter which has a switchable backlight for use in dark areas.
- 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.
