SE-0020

The K-33 ELG (environmental logger) is designed to measure up to 10,000ppm (1%) carbon dioxide, temperature, and relative humidity in remote locations. Because of its ultra-low power requirements, it can “wake up”, take a sample, store the data in memory, and go back to sleep. Using battery power only, the sensor can be placed in the field for days or weeks at a time.

With multiple input and output options and support for I2C and Modbus protocols over TTL levels, the K-33 ELG combines the quality of our dual infrared NDIR sensor technology with configuration options to satisfy even the most critical applications.
