30% CO2 + RH/T Data Logger with Display Alarm

30% CO2 + RH/T Data Logger with Display Alarm

Order Catalog



This Portable Data Logger is designed to measure carbon dioxide, temperature, and relative humidity. It can “wake up”, take readings, stores them in memory, and go back to sleep.

The logger is battery operated, and is designed to take up to 15,000 data samples before the internal memory is full. In addition, the sensor can record CO2 levels up to 30% (300,000ppm).

Note that though the sensor inside is designed to remotely log CO2, RH and temperature into log files for downloading at a later time, the addition of the LCD back-lit display allows for real-time data acquisition. The LCD can also be programmed with different alarm levels (Red, Yellow, Green).
