  • Description
  • Details
  • Specification

JK series of Laboratory Muffle Furnace is discontinuous running which being used heating for ultimate analysis and measuring, quenching, annealing, tempering of general small steel parts in laboratories, research and development institutions and academies, as well as used for firing, dissolving and analyst of metal, ceramic. Wonderful door sealing reduce the heat loss, improves temperature uniformity in chamber. Resistance furnace has this function. Programmable controller can simplify complicated experiment process, really reach automatically control and work. 

JK 1200C muffle furnaces for laboratory are the most cost effective high temperature muffle furnace. The furnace chamber used imported Morgan materials from Italy, which is energy-saving 40% and weight lighter about 50% than old furnace, heating elements, Spring wires of Fe-Cr-Al Alloy doped by Mo with special design and furnace temperature controlled by high precision SCR(Silicon Controlled) digital controller with accuracy ± 1 °C and 30 segments program.


Part 1

-- Product Characters 

♦ The external material is SECC steel plate,baking finish. The inner material is silicon carbide ceramics. 

♦ Top heating element has long-life character. 

♦ Temperature is controlled automatically by PID. 

♦ The furnace permits faster heat-up and reduce energy consumption. 

♦ Over temperature protection and over-load protection 

♦ Cyclic system:thermal radiation APO 

♦ PID temperature controller meets full automatic constant temperature function.

♦ Timer:Timekeeping when up to the presetting temperature,power outage alarm indication. 

♦ Unique designed door prevents high temperature gas leaking,ensures safety and simple.Microcomputer PID controller controls temperature accurate, reliably,safely easy to operate. 

♦ Imported PID digital thermometer, accurate temperature control, simple operation. 

♦ Built in precision digital temperature controller is 51 segments programmable to control heating rate, cooling rate and dwell time.Temperature control unit can be separated from furnace, and make moving at easy. 

♦ The furnace temperature is controlled by precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/1C and 51 segments programmable up to 1200C.

♦ Design of sliding down door is for loading materials easily. 

♦ Fast heating and cooling, economic and quick. 

♦ Specifications can be customized according to customer specified. 

-- The Most Concerned:


-- Application:

Muffle furnace mainly used in chemical analysis, physical decomposition and synthesis, super-hard materials (such as ceramic), Rare and precious metal smelt in and purification,metal heat treatment of sintering process research and other scientific experiments. Universities and colleges, scientific research institutes, medical and health, petroleum chemical industry, mining enterprise, quality and technology supervision agencies, and other units laboratory, laboratory are the use of such equipment.

Part 2

-- Service

Warranty: Two year limited warranty with lifetime support, excluding heating elements damaged by user. Within this period, Across International will, at its sole options, replace any components that fail in normal use. Such replacement will be made at no charge to the customer for parts, provided that the customer shall be responsible for any transportation cost. This warranty does not cover consumables and failures due to abuse, misuse, accident or unauthorized alteration or repairs.


(Attention: Any damages caused by the use of corrosive and acidic gases, and any damage from wrong operate and use are not under the coverage of One Year  Limited Warranty.)
