Part Code: T3 814 PL



T3-814 PL Digital Infrared Pyrometers with Thermopile Sensors provides the advantage of noncontact temperature measurement of non-metallic surfaces, painted, coated or anodized metals etc. T3-814 PL IR Pyrometer is designed for easy integration into standard 2 wire system. This format combines the high accuracy of digital signal processing with the simple connection. T3-814 PL Infrared Pyrometer is used for target temperature ranging from 0°C to 1000°C. The electronic assembly is protected by IP 65 rugged stainless steel housing.

The parameters like Emissivity can be adjusted directly at device. Other parameters like Analog Sub Range, Response Time, Peak Picker, Valley Picker etc can be preset ex-works or adjustable via Software Infrasoft. T3 Series is provided with TTL output. Using the USB interface Infralink and Software pyrometer can be connected to PC for parameter setting and data logging.
