THIS 1240 C (2264 F) ELECTRICAL MUFFLE KILN WITH Wi-Fi PROGRAMMABLE TEMPERATURE/TIME CONTROLLER AND 11.5 C.L. SPACIOUS CHAMBER WAS ESPECIALLY DESIGNED FOR WORKING WITH MOST TYPE OF POPULAR MATERIAL SUCH AS: METALS, GLASSES, CERAMICS, POTTERY, GLAZES, STONES, ENAMELS AND OTHER TYPE OF MATERIALS THAT SHOULD BE HEATED UP TO 1240 C (2264 F). THIS KILN CAN BE PROGRAMMED AND CONTROLLED FROM ANY DEVICE WITH WI-FI ACCESS SUCH AS LAPTOP, TABLET, SMARTPHONE, TV, PC AND SO ON. FOR YOUR SAFETY THIS KILN HAS ALSO A SECURE MECHANISM THAT WILL DISCONNECT KILN'S POWER SUPPLY FROM 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 TEMPERATURES DURING FIRING PROCESS AND A DIGITAL, OVER/LOW-TEMPERATURE REGULATION SECURE SYSTEM TO HOLD SAME TEMPERATURE DURING THE WHOLE SOAKING PROCESS. SMOOTHING CIRCUIT DIGITAL GUARD FOR ACCURATE READING AND STABILITY WORK ON FLUCTUATIONS OF ELECTRICITY ISS AVAILABLE AS WELL THAT IS VERY IMPORTANT FOR MOST HEATING PROCESSES.Technical specification:- Brand name: Technical Supermarket;- Model: WF-1240C;- Grade: Commercial;- Single phase, 110V +/- 10% or 230 Vac +/-10% on request. Supplied without an electrical plug;- 2900 Watt / 13 A- Top working temperature - 1240 C (2264 F);- Estimated heating time to 1240 C - 90 minutes;- Continuously working time on 1240 C (2264 F): 30 minutes;- Continuously working time on 1000 C or less (1832 F): up to 12 hours;- Kiln dimensions in MM (inch): H380 x W380 x L450 (14/2.5" x 14.2/5" x 18");- Chamber dimensions in MM (inch): H200 x W200 x L290 (8" x 8" x 11.1/2" and 14" Diagonal)- Two industrial K-thermocouples for more accurate temperature control by two different temperature controllers:1. For your convenience: digital, two-lines, temperature controller only for visual control of temperature inside chamber/inner when you are opposite your kiln;2. Wi-Fi programmable temperature/time controller for programming and controlling your kiln (with or without your physical presence) from PC, smartphones, TV, tablets, laptops and so on.This build-in Wi-Fi controller has next parameters:- 9999 time/temperature programmable segments (steps);- Memory: 9999 programs;- Build-in Wi-Fi smoothing circuit (controller's stability work) digital guard;- Easy to create new kiln program or modify an existing one.- No limit to runtime.- NIST- linearized conversion for accurate K-type thermocouple readings.- Monitor temperature inside of the kiln after the program has ended.- View status from multiple devices at once: laptop, tablet, PC, mobiles, TV etc.Other features:- Ventilation hole on the door (with a stainless steel shutter);- Safety switch mechanism (against electrical shock when you work inside chamber) for disconnecting heating elements from a power supply if door is open or closed not properly;- Position of three coiled heating elements: right, left and top;- Calibrated. Estimated accuracy of SOAKING temperature after stabilization process: +/- 1 C;- You will require a standard screw-driver to fix electrical box with temperature controller, thermocouple and safety switch's mechanism of this kiln by few screws (supplied).- This kiln must be positioned on a fire-resist stand. Heavy metal stand for the kiln is available here;- Set of two ceramic shelves for this kiln with four muffle stand is available here;- Weight - 37 Kg;- Cable - 3 M.Delivery specification:- This WF-1240C electrical kiln with simple temperature-reading and build-in Wi-Fi programmable controllers;- K-thermocouple x 2;- Safety switch mechanism;- Electrical box with both controllers and a secure switch;- Downloadable User Manual and temperature controller instructions;-
