Keep room conditions visible with the Sato Highest II thermohygrometer. Its circular humidity scale and separate digital temperature display let staff check both readings during routine inspection rounds.
Consider it for offices, stockrooms and work areas where staff take readings locally. Match its measurement range and accuracy to your room requirements before selecting it.

Dial humidity and digital temperature
A human hair bundle responds to changes in humidity and moves the dial pointer through a mechanical linkage. Temperature is measured separately by a thermistor and shown on the LCD.
