1000°C Small Muffle Furnace

1000℃ Small Benchtop Muffle Furnace product is mainly for the daily application development of the laboratory,high-quality furnace materials and stable temperature control system to ensure the reliability of the experimental data; the product uses high-purity alumina material as the furnace material, and the high-quality alloy resistance wire is used for heating element.

Features

Furnace Shell

1. The shell is made of metal Q235 low carbon steel, and the surface is electrostatically resistant to paint and anti-corrosion
2. Solid metal frame shell structure, low furnace surface temperature
3. Side-opening furnace door structure, the left hinge is fixed, easy to operate

Refractory

Multi-layer thermal insulation design, double-layer light refractory brick lining with strong structure, high-strength stacking and splicing, no asbestos, low heat loss and low energy consumption

Heating System

1. High-quality HRE spiral resistance wire heating element, the resistance wire is wound on the ceramic support tube, free heat radiation heating in the furnace cavity, energy saving, high efficiency and long service life
2. Heating on three sides (left and right sides and the bottom of the furnace), so as to achieve
3. The silicon carbide bottom plate covers and protects the bottom heating element, which has high mechanical strength, good thermal conductivity, and provides horizontal bearing at the same time.

Temperature Control Panel

1. PID cooperates with SCR control mode, the temperature control is accurate
2. International standardized N-type nickel-chromium-silicon thermocouple, with a temperature measurement range of 0-900 °C, and a long service life
3. The furnace door has a safety protection switch for opening the door and power off

Program Controller

1. Advanced controller that adapts to complex process requirements
2. Simple and direct operation, flexible programming
3. Programmable 30 program segments for a single curve
4. Over temperature and fault alarm, automatic safety protection
5. Optional manual air inlet and automatic clamshell exhaust
6. Optional furnace temperature air rapid cooling control unit to achieve rapid cooling within the furnace temperature of 400 °C
