Moisture Balance: How It Works and When to Use One
A moisture analyser dries a sample while weighing it and shows the moisture percentage in minutes. Learn how it works and which industries use it.
A moisture balance (moisture analyser) combines a precise balance with a heater. It weighs your sample, heats it, and keeps weighing as water evaporates. When the weight stops changing, it reports the moisture content as a percentage.
Why not just use an oven?
The oven method works, but it takes hours and needs separate weighing. A moisture balance gives a result in minutes, so you can check each lot before it is mixed, packed or shipped.
Where it is used
- Grains, pulses, flour, spices and tea
- Pharma powders and granules
- Plastic granules, chemicals and pigments
- Textiles, paper and wood
Tips for good results
- Use a representative sample and keep the amount consistent.
- Spread it thinly and evenly on the pan.
- Set the drying temperature so the sample dries but does not burn.
- Compare against the oven method once to set up your procedure.
