Data Loggers

The testo 177 series of data loggers consists of five different data loggers, measuring temperature (177-T1/2/3/4) and humidity (177-H1). The 177-T3 has two external NTC sensors with a contact closure, which can change the time interval between taking readings, while the 177-T4 provides four external thermocouples.

The testo 177 series stores 48,000 data readings, and all units except the 'Deep Freezer' (177-T1) have onboard displays that provide the current value, minimum/maximum values and alarm conditions. All loggers are supplied with an easy-to-use wall mount.

Testo has also made data collection simple. Instead of only using a computer to download data on-site, Testo has provided two other alternatives. The first is the testo 575 infrared printer, which can print six lines per second. The second is the testo 580 Data Stick which can collect the data from up to 50 testo 175/177 data loggers, and allow users to download the data on an office PC.
