Item # 501 Series, Continuous Multi-Gas Ambient Air Analyzer


The Nova 501 Series Multi-gas Ambient Air Alarm analyzers are designed for the continuous monitoring and alarm of up to four gases in any combination including: O2 deficiency, CO2, SO2, NO, NO2, H2, CO, CL2, NH3, H2S, % RH, and temperature of ambient air.
A built in pump draws in the sample for analysis. A 1/4" plastic tube may be attached to the analyzer to sample a different area, if desired. Alarms are provided for all gases. An audible 'Sonalert' will sound if any reading goes into alarm and an indicator light beside each digital meter shows which gas is in alarm. A reset button is provided to silence the alert.

One low O2 alarm and one high alarm for all other gases. Separate relay contacts for each gas with 5A rating. Separate indicator lights. Common 'Sonalert' audible alarm with reset button. Field-adjustable set points.

Unique Applications
Warm up time is approximately two minutes however NO and NH3 may take up to 2 hours for full stability. The operating humidity range for this series of analyzers is 0-90% RH non-condensing. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
