G110 - halogen moisture analyser

The oven method in a single instrument

The G110 moisture analyser weighs the sample, dries it under a halogen lamp and works out the moisture content from the difference in mass. It is the same principle as the oven method in a laboratory, except that weighing, drying and calculating happen in one instrument and no dishes are carried between a balance and an oven.

A weighing range of 110 g with a readability of 0.005 g makes it possible to measure materials that cannot be calibrated into humimeter meters: very small samples, liquids, pastes, or simply unusual materials that turn up once.

When an analyser and when a humimeter meter

The oven method is accurate but slow - a single determination takes from a few to several dozen minutes. If the material has a curve in one of the humimeter meters, the result is there in seconds and without destroying the sample. The G110 stays the right choice where no curve exists or where a reference result is needed.

G110 or G100

Both analysers share the same weighing range of 110 g, the same heating chamber and the same set of programs. They differ in one number: the G100 reads to 0.001 g, the G110 to 0.005 g. On a sample of a few grams that difference translates directly into the resolution of the moisture result, so the G100 is chosen for the smallest samples and the G110 wherever 0.005 g is entirely enough.

Your benefits measurement by the reference method - from the difference in mass, with no calibration curve covers materials that humimeter meters have no curve for: liquid, pasty, unusual fully automatic drying to constant mass 15 drying programs of your own, each with its own time and temperature three heating rates and three criteria for ending a measurement result shown as moisture in per cent, dry mass and residual mass RS-232 interface to a PC or a printer

How a measurement works

1. Put the empty aluminium dish on the holder and tare the balance.
2. Spread the sample evenly on the dish in a thin layer, 2 to 5 mm is recommended - this decides whether the material dries evenly and whether the result is repeatable.
3. Choose the drying program: a temperature between 40 and 199 °C, a time from 1 to 99 minutes and a heating rate.
4. Close the chamber. The instrument dries the sample and ends the measurement automatically, once the mass has stabilised, after the set time or on the operator’s command.
5. Read the result. The conversion button switches the display between moisture in per cent, dry mass and residual mass.

Sample dishes The dish is 92 mm across and 20 mm high, and the sample is spread in it in a layer of 2 to 5 mm. The dishes are disposable in the sense that with materials that bake on or are greasy it is easier to change the dish than to clean it - which is why the manufacturer supplies them in sets. Art. no. 12154 is a set of 50 that fits both the G100 and the G110.

Calibration

A 100 g calibration weight is included. The calibration is done once the instrument has warmed up - the manufacturer recommends waiting about 30 minutes after switching on - by holding the zero button for roughly 6 seconds and following the display.
