The RTR-52Pt wireless data logger uses industry standard three wire Pt-100 RTD sensors available from many sources. With a temperature measurement range from -200°C to 600°C, the RTR-52Pt is ideal for cryogenic applications including liquid NO2. In addition, it has an IP-64 water resistance rating. The RTR-52Pt is compact, portable, and battery operated. Sensors are attached using a standard three wire screw terminal block.
