2.3. Intended use

A moisture analyzer MAX series is designed to determine relative moisture content in small samples of various substances, determine dry mass content in small samples and determine mass of weighed objects. MAX series ensures fast and precise determination process of water content in a tested sample, and application of a graphic display considerably simplifies functioning, operation and carrying out measurement processes. Moisture analyzer MAX series can be used to determine humidity content of different materials. At the initial stage of measurement, the device precisely determines the mass of an object placed on instrument’s weighing pan. As mass reading is stabilized, the sample is quickly heated by halogen lamps or IR emitters, causing humidity evaporation from the tested sample. While sampling, the moisture analyzer is continuously checking the decline of mass, and on calculation, it displays current moisture content in a tested sample. Compared to conventional methods of humidity content determination of various substances, application of moisture analyzer MAX series considerably shortens measurement time and simplifies testing procedure. The moisture analyzer allows for setting multiple parameters which influence the procedure of moisture content determination in a sample, such as: temperature, time, drying modes, etc.

2.4. Inappropriate use CAUTION!

Do not open the drying chamber during drying process. Moisture analyzer features a halogen lamp which is a very powerful heat source. Thus, user should pay special attention no to touch those elements of a moisture analyzer that get hot while drying procedure (i.e.: disposable pan, pan handle, and inner shields of the drying chamber). Remember that some of tested samples may become dangerous if heated (appearance of poisoning vapours, danger of ignition or explosion). A moisture analyzer MAX series is not intended for dynamic weighing. Even if small amounts of a sample are added to taken off the weighing pan, the mass readout should be taken only on stabilization of measurement result (appearance of stability pictogram on the display). Do not place any magnetic materials on the weighing pan, as this can cause damage of the measuring system of the instrument. Be sure to avoid impact shock and overloading the moisture analyzer in excess of the prescribed maximum measuring range (max capacity), minus any possible tare weight that has been applied).
Never use the moisture analyzer in an environment endangered by an explosion!
This moisture analyzer has not been adjusted for operation in explosive areas. There must not be any modification made to the moisture analyzer.
