All the loggers which have a display can immediately provide a quick overview of the current reading, the last value saved, maximum and minimum value and the number of times the limit has been exceeded.
175 H2 Datalogger 177 T4 Professional Data Logger
Non volatile memory for secure data
The Testo 175 and 177 data logger series provide you with security in the knowledge that vital data will not be lost if the battery is dead or removed. As the battery can be changed by the user it is possible to have interrupted data logging and documentation over a period of several years by calculating the battery life of the logger using ComSoft 3 software. This is a real advantage for efficient and controlled measurement.
Extremely reliable
All of the data loggers have a real time clock (RTC) with an accuracy of plus or minus 2 minutes per month. The robust, non skid ABS casing has a non rigid surface which guarantees protection from humidity and mechanical strain. Some of the loggers have a protection class of IP 68, and are tamperproof with options for a padlock.
ISO/DKD calibration services
In many industries, such as pharmaceutical manufacturing, the use of measuring instruments without the correct calibration is practically unimaginable. Testo makes it possible to calibrate all logger types to the highest possible standards, and is unique worldwide with its combination of DKD calibration laboratories, accredited to ISO 17025, for temperature, relative humidity, velocity and pressure. ISO calibrations, which are a cheaper alternative to DKD calibrations, are accepted by many audits in accordance with ISO 9001, HACCP, GMP, FDA, VDA 6.1, ISO TS 16949 etc.
Windows compatible software
Testo ComSoft 3 Basic and ComSoft 3 Professional Software have all the functions needed to save your logger data quickly and reliably. The logger can be programmed to start via key, according to date and time or via PC. The logger can be stopped once a certain number of measurements have been reached, according to date or time or simply when the memory is full, manually via PC or via the testo 575 printer or testo 580 data collector. The wraparound memory program enables continuous measurements with the oldest value being written over.
