K-33 BLG 30% CO2/Temp/RH Data Logging Sensor

SE-0027

The K-33 BLG (bio-logger) sensor is designed to measure percentage of carbon dioxide up to 30%, as well as temperature and humidity. This makes it an excellent sensor for enclosed applications like incubators.

The K-33 BLG sensor has two 3 mm tube fittings for remote draw or pump sampling measurement. Easily remove the tube cap to use it as a diffusion sensor. Because of its ultra-low power requirements, it can be battery powered to log data to its internal memory.

With multiple input and output options, and support for I2C and Modbus protocols over TTL levels, the K-33 BLG combines the quality of our dual infrared NDIR sensor technology with configuration options to satisfy any remote data logging application.
