- Continuous display of temperature, humidity and dewpoint
- Max. and min. value display
- Battery monitor
- Additional advantages testo 608-H2: LED
- alarm reports limit value violations High
- accuracy ±2 %RH
The low-budget hygrometer testo 608-H1 continuously measures humidity, temperature and dewpoint. The large display is easily legible even at a distance, the suspension and standing fixtures allow flexible positioning on a table or the wall.
testo 608 has a max./min. value display and a battery monitor. Thanks to the long-term stable sensor, you can rely on correct measurement results even after years.
testo 608-H2, the precise alarm hygrometer, reliably reports humidity and temperature limit value violations, e.g. in garden centres, storerooms, cleanrooms, museums, laboratories etc.
