The European norm ISO 589:2003 Hard Coal – Determination of Total Moisture ensures samples are dried between 105 C – 110 C in a drying oven featuring nitrogen blow possibility with flow equal to about 15x capacity of the oven per hour.
Available models
• SLWN1 – laboratory oven with dry nitrogen blow system of the chamber; the kit includes connections, valves and a laboratory
• rotameter (which can be calibrated)
• SLWN2 – laboratory oven with dry nitrogen blow system of the chamber; the kit includes connections, valves and a tech rotameter (which cannot be calibrated)
Available chamber capacity:
• 15l (SLWN1 15, SLWN2 15)
• 32l (SLWN1 32, SLWN2 32)
• 56l (SLWN1 53, SLWN2 53)
• 112l (SLWN1 115, SLWN2 115)
• 245l (SLWN1 240, SLWN2 240)
Calibration:
• Calibration in air in 9 points (corners + geometrical center) of the chamber at 1 selected by the Customer temperature in accredited laboratory. Calibration is confirmed by ‘Calibration certificate’.
• Calibration in nitrogen in 9 points (corners + geometrical center) of the chamber at 1 selected by the Customer temperature in accredited laboratory. Calibration is confirmed by ‘Calibration certificate’.
• Calibration of laboratory rotameter in 3 points temperature in accredited laboratory. Calibration is confirmed by ‘Calibration certificate’.
