Testo Inc. has expanded its 176 data logger series. The Testo 176 T1 is a one-channel temperature logger built for tough environments. It can provide temperature measurements in extreme conditions and its metal housing protects the data logger from dirt, impact and moisture. The Testo 176 T2 is a two-channel temperature logger with an external sensor, allowing for temperature monitoring in refrigeration chambers. The Testo 176 T3 data logger jumps to managing four channels of temperature data with a metal housing and comes with external thermocouple connections. The 176 T4 is a four-channel temperature data logger that can provide parallel temperature measurement readings at up to four different sites using thermocouple probes. The Testo 176 H1 and Testo 176 H2 are both four-channel temperature and humidity data loggers with external sensors. The company says the H1 has an easy-to-read display right at the unit, while the H2 is protected by a metal housing, making it ideal for more rugged locations. The top-of-the-line in the series is the Testo 176 P1 data logger. The P1 is a five-channel pressure, temperature and humidity data logger with both internal and external sensors and a display right at the unit that can store up to 2 million measurement values.
