THIS IS VERY USEFUL 1240 C ELECTRICAL MUFFLE KILN WITH A PROGRAMMABLE TEMPERATURE/TIME CONTROLLER AND 42 L SPACIOUS CHAMBER THAT IS ESPECIALLY DESIGNED FOR WORKING WITH ALL TYPES OF MATERIALS ON TEMPERATURES BELOW 1240 C (2264 F). FOR YOUR SAFETY THIS KILN HAVE A SECURE MECHANISM THAT WILL DISCONNECT KILNS POWER SUPPLY FROM ITS HEATING ELEMENT/S IF DOOR OF THE KILN IS OPEN OR CLOSED NOT PROPERLY. IT HAS ONE 16-MM HOLE WITH A STAINLESS STEEL SHUTTER ON THE DOOR TO SEE FIRING OBJECT/S DURING ALL FIRING PROCESS. THIS KILN HAS ALSO A DIGITAL, OVER/LOW-TEMPERATURE REGULATION SECURE SYSTEM TO HOLD SAME TEMPERATURE DURING THE WHOLE SOAKING PROCESS AND A SMOOTHING CIRCUIT DIGITAL GUARD FOR ACCURATE READING AND STABILITY WORK OF THE TEMPERATURE CONTROLLER ON FLUCTUATIONS OF ELECTRICITY THAT IS VERY IMPORTANT OPTION FOR MOST PROFESSIONAL FIRING PROCESSES.Technical specification: Brand name: Technical Supermarket; Manufacturer: Treatment of Surfaces LTD (London); Model: R-310P-2022; CE.
