Mettler Toledo HB43 Membrane Keyboard Keypad Repair

Your HB43 Membrane Keypad Switch Halogen Moisture Analyzer is used for determining the moisture content of almost any substance. The instrument works on the thermogravimetric principle. At the start of the measurement the HB43 Operator Keyboard Moisture Analyzer determines the weight of the sample, the sample is then quickly heated by the integral halogen heating module and the moisture vaporizes. During the drying process the instrument continually measures the weight of the sample and displays the reduction in moisture. Once drying has been completed, the moisture or solids content of your sample is displayed as the final result.

Of decisive importance in practice is the rate of heating and even heating of the surface of the sample. In comparison with conventional infrared heating or the drying oven method, for example, the halogen heating module of your instrument needs a shorter time to reach its maximum heating power. It also allows the use of high temperatures, an additional factor in shortening the drying time. Uniform heating of the sample material ensures good repeatability of the drying results and makes it possible to use a smaller amount of sample.

All parameters of a measurement (drying temperature, drying time, etc.) can be pre-selected. But your HB43 Switch Membrane Moisture Analyzer offers many other possibilities. To avoid exceeding the scope of this introduction, only a few of these are listed here:
– The built-in database contains predefined drying methods for many products. You can easily adjust the parameters of the individual methods to suit your needs.
– The drying process can be adjusted to suit the type of sample
– You can choose between various types of result display
– Your settings and the measurement results can be recorded
– Your settings are protected even if there is a power failure
– The RS232C data interface fitted as standard allows your moisture analyzer to communicate with an external printer or with a computer.
