SANSEL Model BCAL 40, Black body Calibrator is used to measure the accuracy and performance of non-contact fever detection systems, like medical thermometer & image scanner. Now it is being used in relation to COVID-19 (corona virus). This Blackbody Source meets the demand for a simple cost effective solution but high accurate device for the calibration of thermal imager and IR thermometers that are used at temperature around that of the human body. Unlike Heat only devices, This model uses a solid state Heat & cool Technology, so that this can be generate both Heat and Cool. This having benefits to maintain the block temperature in different ambient temperature. BCAL 40 using True colour 3.5” Touch screen display, easy to read multi parameter at the same time like Block temperature, Set temperature, Control status, Output % level, range of the equipment, displays both °C & °F and two Touch screen soft keys are used for settings and one more advantage of help menu to guide the operating Instruction of the equipment. Hence no need of hard copy of Instruction manual.
