Sato Highest II 7542-00 Temperature and Humidity Meter
:
The Sato Highest II 7542-00 temperature and humidity meter combines a humidity dial with a digital temperature display for straightforward checks of indoor conditions.
- Humidity measurement: Human hair sensor, covering 20 to 100% RH.
- Temperature measurement: Thermistor sensor, covering 0 to 50°C.
- Wall mounting: Bracket supplied for installation.
- Simple power supply: Digital thermometer operates on one AA battery.
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.

Monnit ALTA® Wireless Thermocouple Sensors leverage Monnit’s award-winning remote monitoring platform to remotely monitor high-temperature applications, such as commercial ovens, kilns, and chimneys. Users benefit from a wireless data transmission range of 1,200+ ft, bank-grade security, and a temperature range of up to 400°C (752°F).
Monnit’s thermocouple is user-programmed to sleep for a specified interval, awake, capture analog data, and then convert this measurement into a temperature. If the sensor captures temperatures outside of user-specified thresholds, an alert is sent via text, email, or call. Monnit’s hardwired thermocouples feature a needle-style probe at the end of a 6’ lead (a K-Type Quick Connect Thermocouple is also available).
