Description

THIS 1240 C (2264 F) TOP-LOADED ELECTRICAL MUFFLE KILN WITH A 32-SEGMENT PROGRAMMABLE TEMPERATURE/TIME CONTROLLER AND 74 CUBIC LITER SPACIOUS CHAMBER WAS ESPECIALLY DESIGNED FOR WORKING WITH CERAMICS, POTTERY, GLAZES AND OTHER TYPES OF MATERIALS THAT SHOULD BE HEATED UP TO 1240 C. THIS KILN HAS A 32-SEGMENTS (TEMPERATURE-TIME STEPS) PROGRAMMABLE TEMPERATURE-TIME CONTROLLER WITH A DIGITAL, OVER/LOW-TEMPERATURE REGULATION SECURE SYSTEM (FOR HOLDING SAME TEMPERATURE DURING THE WHOLE SOAKING PROCESS) AND A SMOOTHING CIRCUIT DIGITAL GUARD FOR ACCURATE READING AND STABILITY WORK OF THE PROGRAMMABLE CONTROLLER ON FLUCTUATIONS OF ELECTRICITY THAT IS VERY IMPORTANT OPTION FOR MOST CERAMIC, GLAZING AND POTTERY FIRING PROCESSES.
