PMD - Moisture Meter

Precision Microwave Device (patented)

The PMD 2450 utilizes microwave transmission by measuring attenuation and phase shift to analyze moisture content. Originally developed by the founder of InduTech and continuously improved, this is the 4th generation of this instrument, with noticeably increased accuracy up to 0,1% , especially when dealing with thin layers and measuring non-homogenous products.

Measuring parameters:
moisture content carbon in flyash density of aqueous solutions / Brix


  • in the chute
  • main belt
  • bypass belt
  • in pipelines
  • in tanks

PMD 2450

Precision Microwave Device (patented) (2001 2015)

The PMD 2450 covers the experience gained over 4 generations of the instruments, based on the microwave transmission and the phase method, which was developed by the founder of the company. The original method was remarkably improved by Indutech. This gains large advantages compared to earlier generations of the instrument, in a noticeably increased accuracy, especially for thin layers, inhomogeneous products and concentration measurements.

Measuring Principle:
Microwave-Transmission measurement; the measured material is transmitted with microwaves.

Measured Parameters:
Moisture of non- and low- conductive materials

Layer thickness:
40 mm 500 mm for standard material.

Particle size:
up to 100 mm, ideal < 20 mm.

Microwave evaluation unit must be installed as close as possible to the microwave antennas.

versions for zone 21 or 22 are also available for this device.

Remote service:
per modem or internet connection is available for this device. This saves time and money.
