T3-250
Temperature Range : 250°C to 2500°C
Highly Accurate On-Line Infrared Non-Contact Pyrometer in Two-Wire Technology
T3-250 PL is specially designed IR Pyrometer of T3 Series family for non-contact temperature measurement in demanding industrial environments. The Pyrometers are highly accurate and compact by nature with stainless steel housing to provide high operational safety for harsh industrial environments. The Pyrometers are designed for high-temperature applications between 250°C….2500°C.
The parameters like Emissivity can be adjusted directly at the device. Other parameters like Analog Sub Range, Response Time, Peak Picker, Value 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
