humiditytemperaturelight

Product description
The KBF PRO 720 is a constant climate chamber designed for material testing and conditioning over an extended temperature and humidity range. It covers dry temperatures from -20 °C to +100 °C and humidity-controlled operation from 10 % to 98 % RH. The unit supports flexible water-supply options, offers optional ICH photostability and plant-growth light modules, and reduces energy consumption by up to 40 % compared with the previous KMF model.
