The Reed Instrument SW700 Heat Stress Stopwatch takes both, relative humidity and air temperature measurements to formulate heat index and dew point – crucial for establishing the “feels like” temperature or human-perceived comparable temperature. The SW700 is equipped with a silent operation option, 10 hour countdown timer, audible alarms, 99 lap counter with 30 lap/split memory and fastest/slowest/average lap recall. An IPX4 rating for water resistance, a full LCD display, LED backlight and both a solar and battery power option, all make the Reed SW700 a staple in a variety of application requirements.
