1. Testo Multi data logger 174H Measured variable
Monitor the storage of temperature and humidity-sensitive goods, whether food, archives, or rust-prone metal parts. Alternatively, discreetly and unobtrusively control the building climate to stay informed about your tenants' ventilation behavior. The long-term stable integrated sensors in the testo 174H mini data logger reliably and securely capture temperature and relative humidity in the measurement environment. The display shows the current measurement values and any potential limit violations, with up to 16,000 measurement values stored. Conveniently, the standard batteries (2x CR 2032) can be replaced by the user at any time.
For programming and reading your data logger, as well as evaluating the measurement data on a PC, you can choose from three software versions:
- ComSoft Basic software, available as a free download, for quick programming of the data logger and simple data analysis.
- ComSoft Professional software, additionally available optionally, offers various options for more detailed evaluation of temperature and humidity values.
- ComSoft CFR 21 Part 11 software, additionally available optionally, is optimal for the specific requirements according to CFR 21 Part 11 in the pharmaceutical sector.
To program and read the mini data logger, you will need a USB interface.
Note: Please download the latest software version before operating the USB interface.
