HI93640N portable thermohygrometer provides reading with high precision and quick response time for both RH (Relative Humidity) and tem- perature. HI93640N is a compact, portable and versa- tile instrument to monitor relative humidity anywhere. The built-in thin-film capacitance sensor as- sures accurate measurements from 10 to 95% RH with a resolution of 0.1%
The Hanna Instruments HI93640N is a compact, portable instrument designed to measure relative humidity (RH) and temperature with high precision. It features a built-in thin-film capacitance sensor capable of measuring RH from 10% to 95% and temperatures from -20°C to 60°C (-4°F to 140°F). The device includes an LCD display, detachable sintered cap for protection, and operates on three AA batteries.
| Relative Humidity Range | 10.0 to 95.0 % RH |
|---|---|
| Temperature Range | -20.0 to 60.0°C / -4.0 to 140.0°F |
| RH Resolution | 0.1% RH |
| Temperature Resolution | 0.1°C / 0.1°F |
| RH Accuracy (50 to 85 % RH) | +3 % RH |
