The iSense CO2 and Oxygen Combination Monitor and Data Logger is designed measure, log and control both carbon dioxide and oxygen levels drawn from a gas source. This makes it useful for controlled atmosphere (CA) storage applications, incubation, fermentation or for bench-top gas analysis. It features a built-in sampling pump, real-time LCD readout, and built-in data logging. The iSense can be easily calibrated using fresh air.
- Controlled atmosphere monitoring and gas supply control
- Incubation and fermentation monitoring and control
- Environmental safety monitoring
Building on our knowledge of gas sensing technology this unit combines a high-accuracy NDIR CO2 sensor with an ultra-stable Zirconia O2 sensor to provide accurate measurements of both of the detectable major atmospheric composition gases.
Built-in data logging memory can store up to 60,000 time-stamped CO2 and oxygen levels at a user-configured time interval. In addition, the iSense is designed to be calibrated using ambient (normal outdoor) air.
The iSense includes an open pig-tail connector designed for permanent installation and process monitoring control. The M12 barrel connector has CO2 and oxygen level outputs over RS485, relay and power. The USB port allows data collection via the GasLab software.
