Calex Electronics has announced the launch of its new Convir FTK fixed infrared temperature calibration checker, a portable accurate 95C or 120C source to check IR sensor systems. Two models are available, offering two different calibration temperatures. The FTK 95 heats up to 95C, and the FTK 120 goes to 120C. Both units reach and stabilise at these temperatures in approximately 12 minutes and have an LED to show when they are up to the correct temperature.
They both offer a stability of less than +/-0.2C drift at a temperature of 20C. The large 50mm diameter target area allows all infrared temperature sensors, even those with wide fields of view, to be mounted far from the FTK, which helps to ensure there are no accuracy problems as a result of the front of the sensor being heated. The target itself has an emissivity of 0.98, suitable for calibration. The FTKs are made of stainless steel. Being 65mm x 94mm, the FTKs can be used to check fixed infrared sensors where they are installed.
