Product Description

The Labmart HSETIN HT-6899 is a high-temperature, non-contact infrared thermometer designed for industrial temperature measurement up to 2200°C. It also features a Type K thermocouple input for contact temperature measurement up to 1370°C, providing dual-mode temperature measurement for demanding applications.

Product Overview

The HSETIN HT-6899 High Temperature IR Thermometer is designed for measuring the temperature of hot, moving, inaccessible or potentially hazardous surfaces without physical contact.

Its infrared measurement system covers an exceptionally wide temperature range of -50°C to 2200°C, while the integrated Type K input allows contact measurement using a compatible Type K thermocouple.

With a 50:1 distance-to-spot ratio, adjustable emissivity, laser targeting, fast response and backlit display, the HT-6899 is suitable for industrial inspection and high-temperature process monitoring.
