Micro Measure Ltd.

MODEL:AS-300 (General, large size)

Enabling more accurate measurement than ever before, the AS-300 outperforms attenuation formula by a wide margin in accuracy.

High-accuracy delay time measuring method

Measuring with the microwave time, the AS-300 outperforms attenuation formula by a wide margin in accuracy.

Measuring the inside moisture content

Average moisture content of an entire object to be tested including the inside at the center can be measured accurately.


The AS-300 enables the instantaneous measurement of the object at a rate of 100 times per second.

Measuring in wider area and higher moisture contents than AS-200

For an object with large particle diameter or asperity giving rise to error, the AS-300 has greater accuracy.

Suitable moisture meter for ceramic sidings (exterior walls)

The AS-300 can measure the moisture content of ceramic sidings with patterns and asperities accurately. The one with conveyor mechanism and the high-speed type measuring at a rate of 3 objects per second are also available, with which we have a track record in measuring a number of objects with moisture. Please consult us to find the best one for you among our wide range of specifications and sensors.
