Both products do the same core job. They serve different buyers.
Both calculate heat index from temperature and humidity using the NOAA/OSHA formula. The difference is how the data is delivered, documented, and scaled across multiple sites.
Choose HeatAlert® Monitor (Standalone) If You Need:
A proven, ready-to-deploy heat index monitor with immediate visual warnings for workers on the floor.
- Something deployed before next summer's heat season
- A standalone unit that doesn't depend on Wi-Fi or IT involvement
- Highly visible strobe alerts workers see from across a facility floor
- 1 to 10 facilities, each managed independently
- A traditional, permanent hardwired installation
- To avoid cloud subscriptions or data plans
Join the HeatAlert Connect™ Waitlist If You Need:
Continuous heat index logging, OSHA-defensible documentation, and centralized monitoring across multiple sites.
- Continuous compliance documentation an auditor can pull instantly
- Email alerts to your EHS team when thresholds are crossed
- Centralized monitoring across multiple facilities
- Historical data exports for OSHA inspections or workers' comp claims
- Plug-and-play installation without electrician involvement
- To be first in line when HeatAlert Connect™ launches publicly in 2027
A note about the related HeatAlert® passive sign
Both products on this page are heat index monitors that calculate apparent temperature from air temperature and humidity. They're different from the passive HeatAlert® sign — that product is a bimetallic visual warning that responds to air temperature only ($189–$239). The passive sign sits at every outdoor exit as a visible warning; the monitors on this page provide the underlying measurement and documentation. Most facilities deploying a heat-illness prevention program use both together.
