Minimum Free Space Oven (ASTM & ISO)/MFSU

Overview

Measuring a sample's weight loss upon drying is one way to determine the amount of moisture in coal. As needed by the test criteria, the MFSU, which is utilized for this drying process, features a compact heated chamber that provides the lowest practical volume, or minimum free space.

MFSU is a Universal Minimum free space oven that can work as per ASTM, ISO & BS test methods.

Minimum Free Space Oven (ASTM & ISO)/MFSU
Standard Features
  • Maximum operating temperature: up to 210°C.
