Sato SK-170GT WBGT Heat Stress Monitor
The Sato SK-170GT WBGT heat stress monitor measures air temperature, humidity and globe temperature to calculate the Wet Bulb Globe Temperature index. Its portable design supports heat condition checks at workplaces, construction sites and sports facilities.
- Black globe sensor: accounts for radiant heat in the measurement.
- Indoor and outdoor modes: selectable WBGT calculation settings.
- Practical monitoring functions: adjustable WBGT alarm, MAX/MIN readings and display hold.
Assess conditions where people work, train or exercise with the Sato SK-170GT WBGT heat stress monitor. Its black globe sensor, temperature measurement and humidity measurement provide a more useful view of environmental heat exposure than air temperature alone.
Use it for site checks in production areas, construction sites, agricultural work and sports facilities. Readings support your heat management procedures; they do not establish a safe exposure limit for every person or activity.
WBGT monitoring for indoor and outdoor work
WBGT stands for Wet Bulb Globe Temperature. The SK-170GT calculates this index using environmental measurements, with separate indoor and outdoor settings.
The wind speed value is entered manually to support the calculation. The instrument does not measure wind speed, so this setting should reflect the conditions at the measurement location.
Functions for site checks
- Adjustable alarm: A buzzer sounds when the set WBGT threshold is reached.
- HOLD: Keeps a reading on screen while you note the result.
- MAX/MIN: Displays the highest and lowest measured values.
- Automatic power-off: Operates after approximately 20 minutes without use and can be disabled.
- Tripod mounting: Supports stationary measurement using a compatible tripod.
- RS-232C output: Enables real-time data transmission with an optional cable.
