With a deep commitment to the global market, Shanghai Dengsheng Instrument has earned international acclaim for its quality.




1. Adopts a microcomputer-integrated intelligent temperature control system with a built-in PID logic calculation module, featuring constant current, constant voltage, constant resistance, constant power, and combined load functions, achieving excellent response speed and control accuracy;
2. LCD screen display interface, providing accurate and reliable temperature control, simultaneously displaying set temperature, operating temperature, constant temperature time, working status, fault codes, and other information;
3. Features a scheduled operation function, with selectable timing functions (none, constant temperature timing, operation timing), selectable timing direction (forward or countdown), and selectable timing units (minutes, hours). A buzzer sounds an alert at the end of the timing period (alert time is adjustable);
4. Modular control system with self-diagnosis, timing, self-tuning, and temperature deviation compensation functions. The over-temperature control module is linked to the over-temperature alarm system, automatically cutting off the heating power and providing audible and visual alarms in case of over-temperature;
5. Employs an independently developed air duct circulation system, supplemented by an adjustable exhaust valve, automatically discharging gases produced during the vulcanization process and drawing in fresh air;
6. The ventilation volume can be adjusted according to the amount of smoke generated during the vulcanization process to achieve optimal vulcanization results and improve product quality. 6. Improved product yield;
7. Extended flanged exhaust valve allows the fumes generated during the vulcanization process to be directly discharged outdoors or into the ventilation duct through a stainless steel corrugated pipe, avoiding indoor air pollution;
8. High-quality mirror-finish stainless steel inner liner, and the outer casing is made of high-quality cold-rolled steel plate with solid powder electrostatic spraying on the surface, providing weather resistance, corrosion resistance, and anti-static properties, and ensuring a healthy laboratory environment without volatile organic compounds (VOCs);
9. SUS304 dry-type stainless steel heating tube heating, heat energy is evenly transferred to the stainless steel tube wall through the magnesium oxide sand layer, with a heat conversion efficiency of over 95% and a service life of over 20,000 hours;
10. Door seal uses high-temperature resistant silicone rubber material, supplemented by high-quality 120-count ultra-fine ceramic fiber cotton insulation material, greatly improving the overall insulation performance and achieving excellent energy-saving effects;
11. Supports running data recording function, with freely adjustable recording intervals and data export (optional: USB interface);
12. Supports custom 30-segment temperature curves to meet complex experimental needs (optional: 30-segment program controller);
13. Supports stepless wind speed adjustment to adjust the ventilation rate and adapt to various material heat treatment operations (optional: fan speed controller).
