Thermostatic test chamber KBF PRO 720

climatictemperaturephotostability

Product description
The KBF PRO 720 is a constant climate chamber for material testing and stability studies with an operating range from -20 °C to +100 °C and humidity control up to 98 % RH. It supports THB conditions (e.g. +85 °C / 85 % RH), offers flexible water supply options for different installation sites and reduces energy consumption by up to 40 % compared with the previous KMF model. Optional light modules enable ICH photostability testing or plant growth applications.
