Perfect Moisture Balances

Rapid, Accurate, Simple to Use

Kern moisture balances set a very high standard for moisture analysis.  All three models provide rapid and accurate methods for moisture content and dry weight analysis of a wide range of products and materials.  In research, manufacturing, and quality control applications it is essential to determine moisture content simply and reliably.  Kern moisture balancess do precisely that, providing moisture content data as a percentage of initial mass or of the residual dry mass.  All moisture analyzer models have a readout of 0.001 g or 0.01%.

Operating a Kern moisture analyzer is easy:

• place sample in drying chamber
• enter test parameters on keypad
• press key to start analysis

Controlled Drying Process

The halogen quartz glass heaters provide constant even drying of the sample at a temperature pre-selected by the operator.  The advanced software closely monitors the temperature in the moisture analyzer drying chamber and maintains it to within 1ºC of the chosen setting. 

• Model MLB heats from 50-160ºC in 1ºC stages.
• Model MLS heats from 50-160ºC with a heating profile selected by user from 4 modes: preheating, standard drying, gradual drying, stage drying.
• Model MRS heats from 30-230 ºC with preheating, standard or gradual drying.

As the analysis progresses the 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 and remains until it is replaced by a new 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 the data acquisition software allows the operator to produce a graph plotting results against time, providing valuable information on speed of drying and confirmation of dry weight stability.  Results of individual tests can be stored in the computer memory for subsequent comparison.

Models MLS and MRS meet GLP/ISO record keeping requirements.

Convenient Calibration

The weight calibration program enables quick setting of the moisture balance’s accuracy.  External calibration weights are required, and are available as optional accessories.  A temperature calibration set, consisting of a measurement sensor and display device, is an available option with every moisture analyzer.
