HIX1800 Big LED Digit Heat Stress Monitor with Alarm

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 gives employers, facility managers, coaches, and caregivers a continuous, at-a-glance reading of indoor conditions.

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. Heat index is the figure referenced in OSHA and NIOSH guidance on working in hot conditions, and it can read considerably higher than the air temperature alone suggests. The HIX1800 makes heat index monitoring simple, continuous, and visible to everyone in the room.

Alarm Behavior

The Alarm will sound for approximately 12 seconds every 12 minutes. The LED will flash continuously while the unit is sensing the alarm conditions that have been entered.
