    K33 BLG 30% CO2 + RH/T Data Logging Sensor
    Regular price $249.00

    POs or wholesale quantity discounts click here

    The K33 BLG (bio-logger) sensor is designed to measure up to 30% carbon dioxide, temperature and % relative humidity, then record them to internal memory. This makes it an excellent CO2 sensor for enclosed applications like bio-incubators or for portable CO2 meters where sampling of high levels of CO2 is required.

    *Please note the sensor diagram referenced in the manual displays an opposite drawing of the actual sensor module itself*


    • Measures 30% CO2, Temperature, %RH
    • Built-in Memory for Data Logging
    • Multiple Industry standard I/O options
