Our moisture balance is a high-precision device that has been specially developed for plaster / gysum analysis. With a maximum weighing capacity of 220 g and a measuring resolution of 0.001 g, it enables exact and reliable moisture measurements. The balance works on the principle of drying with simultaneous weighing. During drying, the weight loss is continuously recorded and displayed as a percentage of the total mass.

The moisture balance has two adjustable heating temperature ranges: 40 °C ... 180 °C and 105 °C ... 360 °C - which are made possible by two powerful radiant heaters: a 250 W infrared heater and a 375 W quartz heater. These heating elements ensure precise and efficient drying results and can be operated independently of each other in timer or automatic mode. For measurement evaluation, the device offers various parameters such as % moisture, % dry matter, % moisture bd as well as g residual weight / kg and residual weight, which enable the sample to be analysed.

The functions include an automatic power-off function which stops the drying process when a constant weight is reached. The automatic power-off can be set to three criteria: start of sampling, sampling interval and weight loss per sampling interval. This allows a high degree of flexibility in controlling the drying process. There is also a timer that can be set from 1 to 180 minutes. Our device is also equipped with a menu lock that prevents accidental adjustment of the parameters. The menu can be locked using a PIN whereas the CAL menu item remains available. The balance has a programme memory with up to 9 memory locations to store and quickly call up different drying profiles. However, this function is only available in combination with the overhead luminous radiant heater.

Data can be transferred to a PC via software which must be purchased separately. All data can also be output via the serial RS-232 interface and USB. The moisture balance guarantees GLP-compliant documentation. The data is output via the Data Bridge software as the balance does not have a built-in printer. The balance also has a 4-digit device ID for unique identification of the device, which enables precise allocation of the measurement data.

Our moisture balance is ideal for the analysis of gypsum in various areas, such as mining, flue gas desulphurisation in coal-fired power plants and recycling. It enables the analysis of free moisture, chemically bound water as well as the degree of purity and water of crystallisation of the gypsum material.
