BS Series Infrared Radiation Thermometers

Optex Thermo-Hunter Built-In2 BS Series Non-Contact Thermometers

Infrared Radiation Thermometer available with three (3) separate sensors of different field-of-views (FOV) and separate analog output (current or voltage) amplifiers

Features

Measuring range: 0 - 500ºC (32 - 932ºF)
Temperature sensor is separate from amplifier for flexible installation.
Three (3) different sensors available: standard focus (ø30/500mm), narrow focus (ø5/100mm) and fine spot measurement (ø2/50mm)
Amplifier units with integrated digital display and analog output (1mV/ºC or 4-20mA)
e-TEACH function simplifies emmissivity adjustment
Measure temperature with any contact-type thermometer
Input the temperature value of (1)
The unit automatically calculates the emissivity ratio and stores result in memory
- Quick response time: 500ms
- Water resistance: IP67

Applications
