HIX1800 Heat Stress Monitor – Big LED Display with Alarm

The HIX1800 Heat Index Monitor is a wall-mounted indoor display that measures temperature, relative humidity, and heat index simultaneously — showing the combined result as a large, bright red 2-inch LED readout visible from over 50 feet away. It helps employers, facility managers, coaches, and caregivers instantly see whether indoor conditions are safe or potentially dangerous for occupants.

Powered via a standard USB wall adaptor (included), the HIX1800 also supports an optional rechargeable battery for 3–5 days of cord-free use. A built-in audible alarm activates when heat index rises above or falls below your preset thresholds, and a 5 VDC alarm output lets you connect an external warning device — siren, strobe, bell — for larger spaces.

What Is Heat Index and Why Does It Matter?

Heat index (also called "feels-like temperature") combines air temperature and relative humidity to reflect how hot conditions actually feel to the human body. High heat index values significantly increase the risk of heat exhaustion, heat stroke, and other heat-related illness — even when the thermometer alone doesn't look alarming. The HIX1800 makes heat index monitoring simple, continuous, and visible to everyone in the room.
