VWR® Digital Thermo-Hygrometers provide continuous, simultaneous measurement of ambient temperature (°C/°F) and relative humidity (% RH) for monitoring laboratory storage conditions, controlled environment rooms, incubators, refrigerators, and cold rooms. Features include: a large dual-parameter digital display, min/max memory function for recording peak and trough conditions, alarm function for out-of-range condition notification, wall-mount or bench-top operation, and a remote probe option for measuring conditions inside closed chambers. Temperature measurement range: typically -20°C to +60°C. Humidity measurement range: 0–100% RH. Accuracy: ±1°C, ±3% RH. Meets GxP and GDP monitoring requirements when used with appropriate data logging accessories.
