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.
Thanks to the large memory for 2 million measurement values, and the battery lifetime of up to 8 years, you can read out the data much less often, even at a shorter measurement intervals. The standard battery (AA) can be easily exchanged at any time by the user.
Programming and evaluation of the data logger
For the purposes of programming and readout of your data logger, as well as the evaluation of the measurement data on a PC, you can choose between three software versions:
- ComSoft Basic software – available for free download – for the fast programming of the data logger as well as easy data analysis
- ComSoft Professional software – optionally available – offers you different possibilities for the detailed analysis of absolute pressure, temperature and humidity values
- ComSoft CFR 21 Part 11 software – optionally available – optimum for the special requirements of the pharmaceutical sector according to CFR 11 Part 11
To program the data logger, you require a USB cable which is not included in delivery. Transfer of the saved measurement data from the data logger to a PC can also take place by USB cable or by an SD card. You can order both as optional accessories.

Applications
Monitoring and documentation of laboratory conditions
The ambient conditions for research projects must frequently be documented in laboratories to check external influencing factors. In addition to recording temperature and humidity, this also includes checking the absolute pressure. There are major requirements in terms of reliability, along with tamper-proofing and data security of the recording instrument, as incorrect documentation could invalidate the whole research result. There are only a few instruments which can log all three measurement parameters at the same time and also offer the required amount of data security.
