HI93640 Compact Thermohygrometers with Built-in Sensor

Product information "HI93640 Compact Thermohygrometers with Built-in Sensor"

Portability and simplicity

Low battery indicator
Dual temperature range
BEPS and low battery warning



HI 93640 is a compact, portable and versatile thermo-hygrometer that monitors relative humidity, anywhere. This simple to use meter is ideal for the HVAC field.

The built-in thin-film capacitance sensor assures accurate humidity measurements from 10 to 95% RH with a resolution of 0.1%.

Designed to be operated with just one hand, the compact housing fits easily in your palm. The design of the rubber keys resists the ingress of dust and protects the instrument from accidental splashes.

A sintered cap can be placed on the sensor shaft for protection in dusty environments. If faster response is desired, the cap can be removed.

The HI 93640 is equipped with BEPS (Battery Error Prevention System) which alerts the user in the event that low battery power could adversely affect readings.
