Our Laboratory Balances is a high-precision device that has been specially developed for plaster 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 scale 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 ATRO as well as g residual weight / kg and residual weight, which enable the sample to be analysed.

The functions include an automatic switch-off function, which stops the drying process when the constant weight is reached. The automatic switch-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 appliance is also equipped with a menu lock that prevents accidental adjustment of the parameters. The menu can be locked using a PIN, whereby the CAL menu item remains available. The moisture analyser 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 light emitter.

The Laboratory Balances offers GLP-compliant output of all data via the Data Bridge software. Intermediate values can be printed at individually adjustable intervals if required. In addition, all data is transferred via the serial RS-232 interface and USB. The printer can be deactivated if required. Data can be transferred to a PC via software, which must be purchased separately. The scale also has a 4-digit device ID for unique identification of the device, which enables precise allocation of the measurement data.

Our Laboratory Balances 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.
