MT.300 Transformer Oil Moisture Meter (Karl Fisher)

The MT.300 micro moisture meter is a high-precision instrument designed for trace water analysis in transformer oil and other samples.

It employs the Karl Fischer coulometric titration method, a globally recognized and proven technique for determining trace moisture content.

Equipped with a high-resolution color LCD touch display and powered by an ARM processor, the MT.300 offers fast, stable, and accurate performance with user-friendly operation.

Its dynamic curve indication, automatic fault diagnosis, and large data storage capacity make it ideal for laboratories and industrial applications across electric power, petroleum, chemical, pharmaceutical, environmental, and research fields.
