The Testo 177 series of data loggers consists of five instruments suitable for wide-ranging and long-term applications. All the loggers except the 177-T1 have a display and immediately provide a quick overview of the current reading, the last value saved, maximum and minimum value and the number of times a limit has been exceeded.

With the new Testo 177 series of data loggers you're secure in the knowledge that vital data will never be lost or changed when the battery is either spent or replaced. Using Testo's software, battery life can be calculated over the course of several years and consequently changed by the user in the field when necessary without worrying about interrupting data logging operation and documentation.

All of the data loggers have a real-time clock (RTC). The rugged ABS casing with non-skid/non-rigid surface guarantees protection from moisture and mechanical strain. Some of the loggers can even be submersed for short periods time. The loggers are also tamperprooof when you use the wall bracket and lock options.
