Testo 174H Mini Temperature & Humidity Data Logger
Keep a record of changing room conditions with the compact testo 174H. Place the logger where temperature and humidity matter, then review current readings and limit breaches on its display. Its internal memory stores up to 16,000 measurement values for later analysis on a computer.
Use it for routine checks in stockrooms, archives, offices and other indoor areas where temperature and humidity trends need to be documented. The sensors are built into the logger, so no separate measurement probe is required.
Choose the Right Package
This product is the 174H logger without the USB interface. You need a compatible USB interface to program the logger and read out its stored measurements. If you do not already have one.
