Very high accuracy moisture and density meter. "On-line" version, for process control. Bypass type.
MW 4260/ MW 4270
The Bypass Microwave Moisture Measuring System MW 4200 has been developed for industrial use. The sturdy stainless steel housing and simple controls make easy to measure moisture under production conditions for many applications.
The patented measuring method achieves accurate moisture measurement unaffected by density, surface structure and colour of the materials being measured. MW 4200 is ideal for measuring moisture in pourable products and raw materials in many industries.
