Sato HIGHEST II Temperature and Humidity Meter
The Sato HIGHEST II combines a dial hygrometer with a digital thermometer for checking room conditions. Its humidity sensor uses a human hair bundle, while a thermistor measures temperature.
Use it as a local indicator where staff need to read temperature and relative humidity during routine inspections. The round display keeps both measurements together in one compact instrument.
Key Features
- Dial humidity indication and digital temperature display.
- Humidity range of 20 to 100% RH.
- Temperature range of 0 to 50°C.
- Wall-mount bracket for installation at the reading point.
- Compact 135 mm diameter body.

Scale interval and display resolution are different from accuracy. The 0.1°C display does not mean that temperature readings are accurate to ±0.1°C.
Where to Use It
Consider the HIGHEST II for rooms, work areas or storage locations where a visible local reading is useful and its accuracy meets the application requirements. Compare the expected conditions and acceptance limits with the specification before selection.
Mount the instrument where the reading represents the area you want to check. Avoid placing it directly beside a heat source, in sunlight or in the discharge from an air-conditioning outlet unless that specific location is the measurement target. Allow the instrument to settle after moving it.
Local Readings or Electronic Records?
If your inspection procedure requires a written record, record the displayed readings together with the date, time and location. If you need to capture changes between inspections, select a temperature and humidity data logger. For multiple locations with central monitoring and alarms, consider a continuous monitoring system.
Installation and Calibration
The supplied mounting accessories include a wall bracket and screws. Follow the instruction manual for installation and care. Tell Seacom if you require calibration documentation so the available service and required measurement points can be confirmed before ordering.
