KSL-1200X Tabletop High-Temperature Box Furnace: Precise 1200°C Temperature Control Makes High-Temperature Sintering "Clearly Visible"

Is traditional high-temperature sintering limited to "blind firing"? Shenyang Kejing’s KSL-1200X Tabletop Box Furnace (7.2L) arrives to break the mold! Reaching a maximum temperature of 1200°C, it features a unique quartz observation window, a three-sided heating design, and a 50-segment intelligent PID temperature control system. Specifically engineered for metal annealing, ceramic sintering, and quality inspection applications in university and corporate laboratories, discover this CE-certified, high-efficiency muffle furnace today.

In the daily routine of materials science experimentation, high-temperature sintering, metal annealing, and various heat treatment processes are often conducted within a completely enclosed furnace chamber. Researchers typically rely solely on cold numerical temperature data to infer the physical or chemical changes occurring inside the material; this state of "blind firing" presents significant challenges to the precise control and management of experiments.

To empower researchers with real-time oversight of sample phase transitions and morphological changes at high temperatures, Shenyang Kejing has innovatively introduced the KSL-1200X Tabletop High-Temperature Box Furnace. With a compact 7.2L chamber volume, this robust and sophisticated device has become a flagship product in numerous laboratories, distinguished by its unique observation window design and exceptional temperature uniformity.

Bid Farewell to "Blind Firing": Empowering Cutting-Edge Materials Research Through Unique Design

The core competitive advantage of the KSL-1200X lies in its ability to transcend the limitations of the enclosed nature typical of traditional muffle furnaces, while simultaneously incorporating deep optimizations to the furnace chamber's thermal insulation and heating structures.

1. φ15mm Quartz Observation Window: Functionality That Goes Far Beyond Mere "Viewing"

A φ15mm quartz glass observation window is ingeniously embedded right in the center of the furnace door. This feature not only enables users to observe—in real-time—the melting, shrinkage, or discoloration processes of samples within an environment reaching temperatures of up to 1000°C, but its design also incorporates a clever, multi-functional ingenuity:

Multi-functional Expansion: The observation port can be fitted with a gas inlet assembly (e.g., utilizing a φ5mm stainless steel barb fitting and an alumina tube) to serve as an entry point for introducing specific protective gases into the chamber. Test Port: This also serves as an excellent feed-through channel, allowing for temperature calibration during the heating process or for *in-situ* measurement of the sample's electrical properties.

2. Three-Sided Heating and High-Purity Alumina Chamber: Achieving Ultimate Temperature Field Uniformity

Temperature gradients are a critical factor that can fatally compromise sintering quality. The KSL-1200X utilizes high-quality molybdenum-doped iron-chromium-aluminum alloy resistance wires as heating elements, innovatively arranged across three sides of the furnace chamber. This three-sided heating structural design fundamentally guarantees a highly uniform temperature field within the 200×300×120 mm constant-temperature zone.

Furthermore, the furnace chamber is constructed from high-purity alumina fiber materials, with its surface coated using a high-temperature alumina coating imported from the USA. This not only significantly reduces energy loss but also enhances thermal reflectivity and heating efficiency, thereby greatly extending the service life of the furnace chamber.

3. 50-Segment PID Intelligent Temperature Control System

The "brain" of the equipment is a standard-issue YD858P temperature controller. It supports 50 segments of intelligent, programmable control; through automatic PID adjustment, temperature control accuracy can reach ±1°C. No matter how complex the heating and cooling curves required for thermal treatment, they can be executed with precision. (Note: Users may also opt for optional PC-based control software to enable real-time tracking and data export of temperature profiles.)

Two Chamber Configurations: Flexible Solutions for Diverse Experimental Environments

To meet the diverse sintering requirements of various materials, Shenyang Kejing offers two heating element configuration options for the KSL-1200X:

Open-Wire Heating Type (Open-type resistance wire lining): The resistance wires are directly exposed within the furnace chamber, providing more direct and rapid temperature feedback. This configuration is suitable for the high-temperature processing of standard, non-corrosive materials.

Corrosion-Resistant Embedded Wire Type (Corrosion-resistant coating embedded wire): The resistance wires are embedded within the inner walls of the furnace chamber and covered with a corrosion-resistant coating. This design features extremely low contamination potential, making it highly suitable for experimental scenarios with stringent environmental requirements, or for processes where slight volatile substances may be generated during sintering. Note: Both models feature a maximum operating temperature of 1200°C (for durations ≤ 30 minutes) and a continuous operating temperature of 1100°C.

**Comprehensive Safety Protection and Exhaust Management Design**

In extreme environments reaching 1200°C, safety always remains the top priority. The KSL-1200X employs a double-layer housing structure, effectively reducing the temperature of the equipment's outer surface.

Notably, the furnace body features integrated inlet and exhaust ports. During the initial stages of sintering, these ports effectively vent moisture and gaseous impurities released by the materials. This not only safeguards high-value experimental samples but also prevents corrosive gases from eroding the heating elements and the furnace chamber, thereby significantly extending the equipment's service life. Furthermore, the unit comes fully equipped with a comprehensive suite of safety features, including automatic power shut-off upon door opening, over-temperature protection, and thermocouple failure protection.

The Shenyang Kejing KSL-1200X Desktop High-Temperature Box Furnace combines a compact 7.2L footprint with a visual observation window, a uniform three-sided heating field, and an intelligent temperature control system. It serves as the perfect desktop-class platform for universities, research institutes, and industrial enterprises conducting metal annealing, fine ceramics sintering, and quality inspection tasks.
