Mini data logger for temperature and humidity

The current measuring values and any possible violations of limit values can be read on the mini data logger’s display.

Its measurement data memory can reliably record up to 16 000 measuring values. Saved measurement data will not be lost even when the battery is empty or being replaced.

The testo 174H mini data logger has internal sensors which measure temperature and humidity. The humidity sensor is a capacitive Testo humidity sensor with long-term stability which has an accuracy of up to ±3 % RH when measuring humidity. With an accuracy of ±0.5 °C, the internal NTC temperature sensor is particularly high-precision and covers a measuring range from -20 to +70 °C.

Particularly practical: the mini data logger runs on standard batteries (2x CR 2032) which you can replace yourself at any time.
