tecal portable dri-block® calibrators Tecal S and H range Dri-Block Calibrator This range of temperature calibrators is ideal for calibrating temperature sensors used in the food and pharmaceutical industries in addition to calibrating any sensors used in the temperature range outlined in the specifications below. S Version: Set required Temperature and Calibrate H Version: Set required Temperature and Calibrate; also programmable for switch test and ramp rate etc. Tecal 140S/H The Tecal 140S provides a complete system for calibrating most types of thermal sensors used in the temperature range of -40°C to 140°C which includes “K” type thermocouples commonly used in the food industries, cold storage rooms and environmental monitoring systems. 140H Where automation in both the field and laboratory are required, the combination of the Tecal 140H with the UPI (see page 13) saves time and money. The user can set the program and leave the unit to calibrate the probes, automatically storing the results in memory. This allows the user to attend to other tasks and when convenient download the results to a computer to print the calibration certificate. Using advanced peltier technology and state-of-the-art mechanical and electrical components, these calibrators can rapidly cover the complete temperature range where speed is of the essence without loss of accuracy or stability. The heater block with a defined measuring zone of 50mm from the bottom of the block allows for different length/active area sensors. Although the quoted accuracy and stability is ±0 .2°C & ±0.05°C respectively, one can often achieve an accuracy of ±0.1°C and a stability of ±0.02°C with high class RTDs and thermocouples.
