Testo 176 H2 | 2 Channel Temperature & Humidity Data Logger

Measure humidity and temperature on two channels thanks to its two connections for external sensors
Memory for up to 2 million readings, up to 8 years of battery life
Robust metal housing and protection against dust and water jets in compliance with protection class IP 65
Three software versions are available for measurement data analysis on the PC, basic software can be downloaded free of charge

The robust metal housing of the non-sensitive testo 176 H2 climate data logger protects it against mechanical impacts. It can therefore measure temperature and humidity even in harsh environmental conditions.

Do your short-term measurements reveal no irregularities? Yet the ambient building or storage conditions still do not meet the designated requirements. The testo 176 H2 is the perfect data logger for analyzing precise climatic development using long-term measurements.

Two external humidity/temperature probes, which you can order when you purchase the climate data logger, can be attached to it. This will enable you to measure temperature and humidity at two different points simultaneously.

With its large measurement data memory (up to 2 million readings can be recorded) and its long battery life (up to 8 years), the data logger is the ideal instrument for the long-term recording of climate data.

The Testo 176 H2 has a robust metal housing, that protects the climate data logger against hard impacts and will maintain its durability even in harsh environmental conditions.

Moreover, it conforms to protection class IP 65 and can therefore be exposed to water jets and dust. This is particularly handy if cleaning is undertaken at the measuring location because this means that the data logger does not need to be removed. The data logger will not sustain any damage even in dusty or dirty conditions.

This climate data logger makes the security of your measurement data top priority. As soon as you start a measurement program and values for temperature and humidity are stored in the data logger, these will never be lost again. Even when the battery is spent or replaced, the data in the testo 176 H2 remains fully available.

Lithium batteries (TL-5903) are provided for the data logger power supply. If a battery is spent, you can change this yourself.

testo 176 H2 climate data logger for humidity/temperature with connections for 2 external sensors (NTC/capacitive humidity sensor) including wall bracket, lock, batteries and calibration protocol.
