Like the quality and features of Mettler, Ohaus, and Sartorius, but not the price? Choose a KERN moisture analyzer. |
Operating a KERN moisture balance is easy:
- place sample in drying chamber
- enter test parameters on keypad
- press key to start analysis
Controlled Drying Process
Most Kern models use halogen quartz glass heaters to provide constant even drying of the sample at a temperature pre-selected by the operator. The newest Kern model, MLS 50-3IR160, utilizes the latest infrared heating technology to afford consistent and accurate results. IR heating is somewhat slower than halogen heating, but avoids the need to replace halogen bulbs and also prevents overshooting the set temperature. The advanced software closely monitors the temperature in the moisture analyzer drying chamber and maintains it to within 1ºC of the chosen setting.
As the analysis progresses the moisture balance displays the current status, keeping the operator updated on each stage of the process. The analysis automatically terminates either when drying is complete and the dry weight is stable, or after a fixed time specified by the operator.
Print or Save Results on PC
The final result is shown on the moisture balance digital display until it is replaced by the next measurement. At the end of the moisture weighing all relevant data concerning initial mass, residual mass, test parameters and results can be printed out via an RS-232 interface. When the moisture analyzer is connected to a PC, results of individual tests can be stored in the computer memory for subsequent comparison.
Models MLS and MRS meet GLP/ISO record keeping requirements.

Moisture Analyzer Applications
Samples with the following properties can usually be determined satisfactorily:
- Granular or powdery, floatable solids.
- Thermally stable materials, which readily give off the moisture to be determined without volatilizing other constituents.
- Liquids, which evaporate to dryness without forming a skin.
