Envco – Environmental Equipment

Features
• Ideal for low gas concentration (ppb detection)
• Easily replaceable plug-in tape cassette
• Cassette tape remainder display included

Its best application then is in monitoring of the target gas at the outlet of an absorption scrubber, as well as in monitoring of the work environment for personnel safety.

Since the cassette can be replaced so quickly and easily by a one touch cassette method, detection of multiple gases is practical.

Applications
• Environmental Monitoring
• Semiconductor Industry
• Manufacturing
