KHQ-P2000 Quartz Lamp Point Heater
Product Overview
The KHQ-P2000 Quartz Lamp Point Heater is a high-power localized thermal loading system designed for high-temperature materials research and engineering testing. The system utilizes a 2000 W short-wave quartz halogen infrared source, focusing radiant energy through a high-reflectivity metal cavity to achieve rapid heating in millimeter-to-centimeter-scale areas. Unlike traditional resistance furnaces that require extended warm-up times, this unit applies high heat flux directly to the target area without preheating. It is ideal for thermal shock, thermal cycling, material failure analysis, and thermo-mechanical coupling tests. The KHQ-P1000 model supports rapid localized heating and laboratory validation for smaller areas. The KHQ-P2000 offers enhanced power capacity, heat flux density, and high-temperature performance, making it better suited for larger thermal loads, steep temperature gradients, and engineering-grade testing. Both models feature a modular focusing structure configurable to match sample dimensions and test requirements.
Product Positioning
2000 W High-Power Focused Thermal Loading
The high-reflectivity metal focusing cavity concentrates short-wave infrared energy to rapidly heat millimeter-to-centimeter-scale regions and deliver high heat flux loads.
Engineering-grade Test Upgrade
Compared to KHQ-P1000, it delivers enhanced power reserve, heat flux density, and high-temperature capability, making it ideal for applications with higher thermal loads and steep temperature gradients.
Product Type
How it works
Quartz lamp point heaters generate high-temperature radiation using a tungsten filament inside a quartz tube, transferring energy to the sample via near-infrared short-wave radiation. Combined with a gold reflector cavity or high-reflectivity metal structures, energy efficiency is improved and heat is concentrated on the target area. Industrial-grade 2000 W quartz-halogen infrared elements typically feature short-wave infrared output around 1 μm, fast response times, and high power density, making them ideal for rapid thermal loading applications.
Actual temperature capability depends not only on power but also on material absorptivity, sample size, surface condition, environmental heat dissipation, reflector cavity design, and the measurement method. Each project requires a comprehensive design based on target temperature, ramp-up time, heating area, and test environment.
Important Notice:The maximum temperature capability of 1800～2000℃ is material- and condition-dependent, representing peak performance under focused, high-absorption scenarios. For formal projects, final specifications should be determined based on specific samples, agreed test conditions, and acceptance criteria.

Usage and Safety Instructions
- ⚠Strong visible and infrared radiation is emitted during operation. Do not look directly at the light source or focus area. Use appropriate eye and radiation protection equipment.
- ⚠The sample, heating head tip, and surrounding structures may be hot. Install heat guards and allow adequate cooldown time after power-off.
- ⚠Keep the air-cooled channel clear. Do not operate continuously if cooling is abnormal, the reflector surface is contaminated, or electrical connections are loose.
- ⚠Infrared temperature readings are affected by emissivity, angle, and spot size coverage. For highly reflective metals, combine with thermocouples or use a calibrated measurement solution.
- ⚠For adhesives, coatings, and materials that may emit volatiles, evaluate ventilation, smoke extraction, and fire safety conditions.
