Compact Thermohygrometers with Built-in Sensor

The HANNA INSTRUMENT HI93640 Thermohygrometer is designed to provide high-accuracy measurements of temperature and relative humidity (RH) anywhere. It features a simple interface and the Battery Error Prevention System (BEPS). Users can easily switch between temperature and RH measurement modes using the RANGE button. Both temperature and RH are measured with a protected integrated sensor covered by a sintered cap to prevent dust interference.
The HI93640 is built to operate reliably in various environments. It displays temperature in both Celsius and Fahrenheit and comes with a removable sinter cap that protects the sensor. Its simple design makes it easy to operate and maintain.

Features of HANNA INSTRUMENT HI93640:
Built-in Sensor: Integrated thin-film polymer (TFPC) sensor accurately measures relative humidity and temperature.
°C / °F Readings: Temperature displayed in Celsius or Fahrenheit. A slide switch allows easy change of units.
Battery Error Prevention System (BEPS): Detects when batteries are too weak to ensure reliable measurements.
