UVA intensity meter for electricians

The Sentry ST510 measures ultraviolet light radiation up to 40 mW/cm². It is designed for technicians who need to verify UVA output in curing, inspection or safety applications. The unit handles both high and low ranges in mW/cm² or µW/cm².

Backlit display and automatic logging

A four-digit dual display with backlight shows readings clearly in dim environments. The meter stores 20 data points and performs measurements automatically once powered. Magnetic mounting and a tripod socket keep the sensor steady during extended sessions.

Compact tool that frees up bench space

The magnetic back and tripod thread let you fix the meter to metal surfaces or a stand without clamps. No external power supply is mentioned, so it runs from its internal source. Builders needing UVC or UVAB measurement should note this model covers UVA only.

Questions about this item

How do I mount the ST510 for hands-free measurement, and what step is often missed?

Attach the meter to a ferrous surface using the integrated magnetic mount or secure it on a tripod via the mounting socket; users frequently forget to remove the protective film from the magnetic back before positioning.

Which components of the ST510 require periodic replacement or recalibration?

The UV sensor is the primary wear item; plan to send the unit for factory recalibration annually and replace the sensor if readings drift beyond tolerance after extended exposure.

At what irradiance level does the ST510 reach its measurement ceiling during continuous UV-A monitoring?

The instrument tops out at 40 mW/cm²; sustained sources exceeding this value will display the maximum reading without indicating the true higher intensity.
