The Testo 176 is a triple input device designed to measure pressure, temperature and humidity. It can be used to monitor the conditions of rooms, fridges or freezers used to store food, pharmaceuticals or vaccines.
As standard, it comes with an internal sensor that allows the device to measure absolute pressure between a range of 600 to 100mbar. The Testo 176 P1 continually measures and documents absolute pressure.
The Testo 176 P1 also contains two external ports for connecting NTC and humidity probes up to the device to measure temperature between a range of -20 to 70°C and humidity from 0 to 100%RH.
Portable and lightweight, the Testo 176 P1 comes in a protective metallic casing, allowing it to be used in dangerous environments. It also comes with built-in memory that can store up to 2million records, and battery life that lasts up to eight years.
