MOISTURE OVEN FOR COAL

ASTM D 3173

This coal oxidation test apparatus is designed in accordance with standardized test methods for determining the oxidation stability of coal by measuring weight loss in a controlled air atmosphere. Ideal for research labs and quality control facilities, the equipment operates under precisely regulated conditions of temperature, airflow, and time, ensuring accurate and repeatable results.

Key Features:

  • Accurate measurement of coal oxidation through weight loss method

  • Controlled airflow system with preheated dry air renewal (1–4 air changes per minute)

  • Exhaust change-over valve to prevent condensation in the flow meter

  • Temperature range: Above ambient to 150°C ± 2°C

  • Built-in timer for setting precise test durations

  • Power supply: 230V, 50 Hz
