Class 220 dataloggers Kimo consists of data loggers for temperature and relative humidity. The KH220 has an internal temperature and humidity sensor and one input for an external sensor. To the external input an additional temperature, humidity, pressure, or universal sensor can be connected. The loggers can be read and programmed with the free Kilog Lite software. If you require additional reporting functionality than you can order the full version of the Kilog software. The loggers have a memory for 1 million measurement points. The housing has a built-in magnet, by which the logger can be easily attached on a metal surface.
