testo 176P1 - Pressure Data Logger


The Testo 176P1 is a 5 channel data logger. It has an internal absolute pressure sensor and connection possibilities for two external temperature/humidity probes. 

When ambient conditions, for example in a laboratory, need to be documented securely and accurately, choose the data logger testo 176 P1. It has an integrated sensor which measures absolute pressure precisely within in the range from 600 mbar up to 1100 mbar.

Additionally Up to two temperature/humidity probes can be additionally connected to the 5-channel data logger Testo 176 P1. A wide selection of probes is available to you for this purpose.

Security and convenience at all levels 

The Testo 176 P1 data logger for absolute pressure, temperature and humidity guarantees high data security and reliable measurement results on the basis of modern measurement technology. 

When temperature/humidity probes are connected, the data logger also shows the dewpoint in the display, in addition to the current measurement values. You can read programmed limit values, min. and max. values, limit value violations as well as the remaining battery life easily from the large display. It is therefore not necessary to read out the data logger to a PC in order to gain a quick overview. 

With its large memory up to 2 million readings 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 standard battery (AA) can be easily exchanged at any time by the user.

Programming and analysis of the data logger

Programming and reading the data logger, as well as the analysis of measurement data, requires the use of a software package. Three different software versions are available:

 ComSoft Basic software – available as a free download – is ideal for fast programming of the temperature logger and easy data analysis

 ComSoft Professional software – also available – offers various options for carrying out detailed analysis of the temperature values

 ComSoft CFR 21 Part 11 software – also available – designed for applications in the pharmaceutical industry with its special requirements according to CFR 21 Part 11
