Sentry ST688P Infrared Thermometer -50 to 1500°C 50:1 DS Ratio

High-Temperature Infrared Thermometer

The Sentry ST688P is a non-contact infrared thermometer built for long-distance measurement. It covers a range of -50 to 1500 degrees Celsius with a 50:1 distance-to-spot ratio. Resolution is 0.1 degrees for precise readings. This tool suits electricians and technicians monitoring extreme heat sources.

Verify Measurement Requirements

Confirm the target temperature falls within the -50 to 1500 degrees Celsius limit before ordering. Ensure the 50:1 distance-to-spot ratio matches the working distance needed for your specific application. Check that a single handheld unit satisfies the job requirements. The device operates as a standalone instrument.

Handheld Diagnostics Integration

The compact rugged design fits into a tool bag for field service and electrical inspections. It requires no external probe or wired connection to operate. The high distance-to-spot ratio frees the operator from approaching hazardous high-temperature equipment. A 3-year parts and 1-year labor coverage period applies.
