Programmable heat treatment muffle furnace is a temperature-programmable high-temperature heat treatment device. It runs automatically according to preset temperature curves, widely adopted for heat treatment of small workpieces, pharmaceutical dry heat sterilization, sample composition analysis, ash measurement and sample melting in industrial enterprises, pharmaceutical industry and analytical testing labs.
Two temperature control ranges are available: RT+10~1300℃ and RT+10~1500℃. Four chamber volumes (4L,7L,18L,36L) meet heat treatment demands from lab-scale samples to medium-batch specimens.
The chamber adopts microporous lightweight high-temperature resistant ceramic fiber boards, featuring low heat storage, fast heating speed and outstanding heat preservation for excellent energy-saving performance. Silicon carbide rods are used as heating elements with high heat resistance, low high-temperature deformation and long service life.
Equipped with intelligent PID programmable control system supporting multi-segment heating, constant temperature and cooling program editing. Multiple safety mechanisms including door-open power-off protection, overtemperature alarm and fault self-check ensure stable and reliable operation.
The outer shell is treated by phosphate passivation spraying for corrosion resistance and neat appearance. The furnace door locking structure ensures good sealing. 3D radiation heating inside forms a uniform temperature field to guarantee consistent heat treatment results of samples.

Auto power-off protection upon door opening: heating stops immediately when the door is opened and resumes automatically after closing, effectively preventing high-temperature scalding and improving operation safety.
Intelligent adaptive PID temperature control algorithm supports parameter self-tuning for precise temperature regulation. Complete heating & cooling programs can be edited, and the unit can shut down automatically once constant temperature duration is completed.
Lightweight ceramic fiber insulation for fast heating and lower power consumption. Surrounding silicon carbide rod layout achieves uniform temperature distribution inside the chamber.
Passivation-sprayed outer shell resists oxidation and discoloration under high temperature. Integrated furnace body plus compression door lock prevents air leakage during long-term high-temperature operation.
Built-in ambient temperature automatic detection. The system calculates initial heating parameters automatically to shorten heating time and optimize energy consumption.
Optimized layout of furnace chamber and controller balances furnace temperature, heating rate and environmental protection, extending service life while saving energy.
Thickened furnace shell owns good heat retention and anti-shock performance, avoiding deformation and cracking under frequent high-low temperature cycles.
Various optional expandable accessories: color touch screen, RS485 communication port, inert gas inlet valve, exhaust chimney, silicon carbide operation platform and more.
Complete safety alarm system: overtemperature alarm, power failure alarm and thermocouple break alarm; fault status can be directly displayed on the operation panel.

Benchtop programmable muffle furnace fits standard laboratory workbenches, no civil foundation required. It can be put into heat treatment tests after power connection and commissioning.
Silicon carbide rod heating elements adapt to medium-high temperature conditions at 1300℃ and 1500℃ with excellent oxidation resistance, stable long-term operation and easy replacement & maintenance.
Multi-segment program temperature control supports automatic execution of complete processes including heating, constant temperature, cooling, buffer and jump shutdown without continuous manual attendance.
Safety interlock switch built into furnace door cuts heating circuit immediately when opened to prevent accidental scalding, complying with laboratory safety standards.
Microporous ceramic fiber chamber features light weight and low heat storage. It cools down rapidly after shutdown for quick start of next batch parallel tests and higher experimental efficiency.
The controller displays real-time voltage and current values, allowing operators to directly monitor equipment load and predict potential faults in advance.
Optimized air duct and heat dissipation layout keeps the controller away from hot chamber, preventing electronic component aging caused by long-term high-temperature baking.
Optional waste gas exhaust structure and gas inlet port are available for tests of volatile samples and oxidation-prone powder sintering.
Three control interfaces optional: basic programmable digital display, color touch screen and expandable touch screen to meet different demands of basic experiments, data archiving and remote communication.

Routine sample ashing and annealing with max process temperature ≤1300℃: Select RT+10~1300℃ series for high cost performance to satisfy most regular high-temperature experiments.
Special ceramic and high-melting powder sintering with sustained temperature close to 1500℃: Adopt RT+10~1500℃ models for higher continuous temperature resistance.
Small university labs with low sample throughput: 4L / 7L models with AC220V power supply, no industrial 380V circuit modification needed.
Enterprise quality inspection and material pilot test with large sample batches: 18L / 36L large-volume AC380V high-power models to hold multiple crucibles at the same time.
Basic heating & constant temperature experiments with limited budget: Choose basic P series programmable digital display version.
Intuitive curve display and experimental data recording required: Upgrade to PV color touch screen version.
