Please note that probes are not included with this product.
This product continually measures and documents temperature, relative humidity and dewpoint, and features a large screen for viewing testing data and a metallic casing for extra protection.
The device features two ports on the bottom for connecting up external NTC/capacitive humidity probes. Once connected the NTC probe is able to measure from -20 to 70°C and humidity probes are able to measure between 0 and 100%RH. The overall accuracy of obtained measurements varies dependant on which probe is connected.
As standard the Testo 176 H1 comes with a metallic casing, impressive measurement memory of 2 million records and has battery life that will last up to eight years even when carrying out constant measurements.
It’s also possible to download data from the 176 H1 to PC.
The Testo 176 H1 Temperature/ Humidity Datalogger can be used to monitor the temperature of fridges and freezers used to store food, pharmaceuticals or vaccines.
