Overview
Enviro Testers compact nitric oxide gas detector, it adopts 2.31 in high-definition color screen for real-time display and adopts gas sensors of well-known brands in theindustry. It is used to quickly detect the concentration of various gases and the measurement of ambient temperature and humidity, and alarm if the measurement exceeds the limit. It is suitable for detecting gas concentration in pipelines or confined spaces and atmospheric environments, gas leakage or high concentration single gas purity where various background gases are nitrogen or oxygen. There are more than 500 kinds of detected gases.
Features
• Detects 1-4 gases simultaneously
• Supports various measurement units
• Built-in pumping measurement with water vapor and dust filters
• Quick response in high humidity and dust environments
• Long-distance sampling capability
• Unaffected by gas pressure variations
• 2.31-inch color screen displays real-time data
