Temperature calibration for thermometers
Published: 31 December 2011 - Michelle Lea
The enhanced CS Series from Eurolec comprises three dry block models for calibration with a temperature control system and a pocket for a reference thermometer. Probe holes at the rear provide a choice of diameters for contact/ probe thermometer accuracy checking; the 'black body' at the front allows checking infrared non-contact thermometers.
Both probe and infrared thermometers can be checked simultaneously at the same temperature without changing inserts. Model CS173 features a range of +30.0 to +199.0°C; models CS174 & CS175 feature a range of 40.0°C below ambient (approx. -20°C) to +85.0°C. All models include a precision accuracy check (PAC) function where the accuracy of the unit is confirmed at 2 preset points and an RS232 output socket; USB output is optional. Model CS175 features 0.01C resolution and± 0.05C accuracy. Precision reference thermometers RT162 or PC Temp RT2 kits with 0.01C resolution are recommended for use in conjunction with the CS series. Suitable for incorporating into HACCP and ISO quality systems, the CS series avoid the inconvenience and time lost due to external calibration. Finding application in food and pharmaceutical labs as a quality control tool or maintenance/diagnostics unit, these benchtop units are easily portable.
