Palmer Wahl DHS520 | Heat Spy High Temperature Infrared with Bluetooth | 600 to 3000 °C
The DHS520 Series is a precision portable infrared pyrometer for high temperature work from 600 to 3000 °C, using a 1 μm spectral response with advanced spectral filtering. Sighting is through a viewfinder with a 9° field of view and a clearly marked 1/3° measuring area (180:1), with the reading shown digitally in the eyepiece. Built-in data logging and Bluetooth or USB connectivity make it suited to route-based monitoring and long-term trending.
Key features
- Internal storage of up to 9999 readings with date and time stamp
- Route Mode and single, latch, burst and route logging modes
- Continuous, peak, average, max and min measuring modes
