Temperature has a direct relationship to curing speed: the higher the temperature the faster the cure. Yet, excessive heat may cause the substrate to distort, which can result in registration difficulties or substrate damage. Heat may also cause UV cure system components to fail. Therefore, understanding temperature is critical to ensuring proper cure and to safeguarding the substrate and system from potential failure.
The MINI SPOT-CHECK SURFACE THERMOMETER is an affordable device for measuring substrate surface temperatures from 0-250F (17-121C) following product exit from the cure chamber. Its small size makes it perfect for taking measurements within confined spaces. By placing the bimetal sensor within close contact of the surface, quick temperature reading can be obtained. With a time constant (time required to reach 63% of an instantaneous temperature change) of 22 seconds, it is accurate to +/-2% of full scale range.
