Climate data logger with robust metal housing – Testo 176 H2

Model No: Testo 176 H2 Part No:0572 1766
The robust metal housing of the testo 176 H2 climate data logger protects it against mechanical impacts. Data logging of temperature and humidity can be done even in harsh environmental conditions.
  • Measures humidity and temperature on two channels thanks to its two connections for external sensors
  • Robust metal housing and protection against dust and water jets in compliance with protection class IP 65
  • Memory for up to 2 million readings, up to 8 years’ battery life
  • Three software versions available for measurement data analysis on the PC, basic software can be downloaded free of charge.


Do your short-term measurements reveal no irregularities? Yet the ambient building or storage conditions does 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. With this, data logging of temperature and humidity at two different points simultaneously becomes possible.With its large measurement data memory (up to 2 million readings can be recorded) and its long battery life (up to 8 years), this temperature & humidity data logger is the ideal instrument for the long-term recording of climate data.

Areas of application for the climate data logger
–  Monitoring and documentation of the air conditioning in buildings
–  Monitoring and documentation of the temperature and humidity in production and in warehouses
