Product Overview

The Benchtop Temperature Test Chamber from ALP Technology is a compact, precision-engineered solution designed for reliability testing and environmental testing of electronic products, components, and materials. This benchtop temperature test chamber is particularly suited for the early product research and development stage, offering a small footprint without compromising on performance. It accurately simulates high and low-temperature cycling environments to evaluate how products resist thermal stress . Ideal for testing small electronic components, military products, and other dust-free materials, this chamber helps engineers identify weaknesses early, improve designs, and ensure product durability and reliability from the very beginning of the development cycle.

Product Features

ALP's Benchtop Temperature Test Chamber is constructed with high-quality materials and incorporates advanced features for precise, repeatable, and user-friendly operation:

Robust Construction: The inner chamber is made from durable SUS304 stainless steel, while the outer shell is constructed from cold-rolled steel plate with a spray treatment for enhanced durability and corrosion resistance.
Touch Screen Programmable Controller: A state-of-the-art controller allows for both constant value and programmable running modes. The screen clearly displays key data including set temperature, actual temperature, total running time, and segment residual time. It can automatically select the compressor's working status based on test parameters for optimal efficiency.
Excellent Visibility and Access: A large observation window on the chamber door provides clear visibility of samples during testing. Additionally, a test hole (available in 25mm, 50mm, or 100mm diameters) on the left side of the chamber allows for routing cables to power and monitor your device under test.
Superior Insulation: The chamber features a thick insulation layer composed of hard polyurethane foam and glass fiber, which minimizes temperature loss and ensures stable internal conditions.
Efficient Air Adjustment System: A forced air circulation system using a centrifugal fan ensures excellent temperature uniformity .
Reliable Refrigeration System: The chamber uses a world-renowned brand, fully closed compressor with eco-friendly R404A refrigerant for powerful and reliable cooling performance.
Smart Mobility: Fixable PU moving wheels are adopted on the bottom, allowing the benchtop unit to be easily moved and securely positioned wherever needed.

Applicable Test Standards

ALP's Benchtop Temperature Test Chamber is designed to comply with both National Standards and Military Standards, ensuring your test results are widely accepted for quality assurance and certification purposes. This makes it a versatile tool for a range of industries, including electronics, automotive, and defense.
