Testo 175 H1 Temperature and humidity data logger

Order-Nr.  0572 1754

The testo 175H1 data logger independently measures and documents buildings’ and warehouses’ temperature and relative humidity. Thanks to the external moisture sensor, the testo 175h1 logger responds with a concise response time. The supplied padlock protects your free-standing humidity and temperature logger from third-party access.

In addition to the current temperature and humidity values, the data logger testo 175h1 shows the dew point on display. Programmed limit values, min/max values, limit violations, and the remaining battery life are also displayed on the screen.to download testo 175h1 datasheet click on the datasheet tab also for complete information about testo 175h1 please visit the testo website.

Frequently Asked Questions

What is a data logger for temperature and humidity?

testo temperature and humidity data loggers are able to measure data at defined intervals. These are then stored in integrated data memory. This includes separate temperature data loggers and humidity data loggers, as well as instruments that take both measurements.

Is a data logger more accurate than a thermometer?

An example of this would be recording temperature changes over the course of an hour in a centrally heated room using a stopwatch, thermometer, pen, and paper. However, using an electronic data logger is much more effective, accurate, and reliable than reading the data manually.
