Extech HT30 brings dependable protection when heat threatens staff comfort and safety. It reads the Wet Bulb Globe Temperature quickly, then shows a clear heat-stress index so teams can act without delay. You can move from indoor to outdoor zones in seconds, and the Extech HT30 keeps pace; the in/out function removes direct-sun error and smooths your workflow.
Accurate Readings, Simple Use
The large digital screen presents air temperature, black-globe temperature and relative humidity in one glance, and every value refreshes rapidly. Because each sensor is fixed in place there is no need for extra probes, so the Extech HT30 delivers fewer parts to track and clean. Two AAA cells power the unit for hours; after a pause the auto-off circuit conserves energy, yet you can override it when long logging sessions are vital.
Built for Real-World Environments
A tough ABS housing shields the sensors from knocks, while the 254 mm length lets you reach above grills or machinery. Link the Extech HT30 to a data system through the built-in RS-232 port; supervisors can archive results or trigger alarms with ease. Workers stay in control even under strong sun, because the black-globe sensor accounts for radiant load that plain thermometers ignore.
Extech HT30 stays reliable thanks to strict CE certification and a two-year warranty. From sports halls to foundries, it offers clear data, smooth handling and trusted build quality, helping you meet safety rules while keeping the team productive.
