Heat sources made from CEM BX-150 dry-blocks allow users to test the accuracy of thermometers and sensors as a system on-site, without the need for a lot of heavy equipment. The CEM BX-150 dryblocks are high accuracy, protable heat sources that are extremely easy to use. Simply plug in, swith ON and set the dry-block to the temperature that you wish to test, insert your probe into the correct size well and record the reading of your thermometer and probe to the displayed temperature of the dry-block and the difference is the error of your instrument. For optimun accuracy and UKAS traceability use a reference thermometer to make comparison measurements.
The CEM BX-150 blocks are controlled by a closed loop microproceesor based digital PID temperature controller system incorporating a heater and precision platinum RTD sensor house in the aluminium block. Fan cooling allows rapid changes in block temperature upon demand. The requred temperature may be adjusted in 0.1 C increments across the range of the instrument using the buttons on the front panel.
These units are ideal for use in a variety of industrial and process applictions. Each unit is supplied with a traceable certification of calibration showing actual test data, which can be used as part of quality assurance programmes.
