Manufacturers in electronics, automotive and new energy industries must subject their products to stringent environmental reliability tests before launch. Extreme working conditions such as intense high-temperature exposure, low-temperature freezing, high-humidity dampness and alternating hot-cold cycles will directly affect product service life and market reputation. Independently manufactured by Chongqing Wanwei Instrument, the WV-HH Series Programmable Constant Temperature & Humidity Chambers (High-Low Temperature Humidity Alternating Test Chambers) provide one-stop solutions for temperature-humidity aging and weather resistance testing of PCBs, chips, automotive wiring harnesses, power batteries and other products.

1. What is a Programmable Constant Temperature & Humidity Chamber?

High-Low Temperature Humidity Alternating Test Chamber is professional reliability testing equipment designed to simulate natural climatic environments. It allows users to freely set high temperature, low temperature, dry, high humidity and alternating temperature-humidity cycle conditions to long-term evaluate the stability and anti-aging performance of products under complex climatic environments. It is essential testing equipment for quality inspection laboratories and quality control departments of manufacturing enterprises.

All constant temperature and humidity chambers from Chongqing Wanwei Instrument are produced in our own factory. Standard-capacity models are in stock for immediate delivery. We support non-standard customization for special testing requirements, including adjustable inner cavity dimensions and customized ultra-low temperature / wide temperature-humidity range units. We provide nationwide door-to-door delivery and lifelong maintenance services to eliminate after-sales worries for enterprises.

2. Four Core Advantages of Chongqing Wanwei’s Programmable Constant Temperature & Humidity Chambers

1. Intelligent Programmable Touch Control System for Fully Automatic Testing & Traceable Data

Equipped with a high-definition touch controller, the unit supports free editing and storage of multi-stage temperature-humidity programs, with dozens of pre-settable high-low temperature & humidity cycle schemes. The equipment automatically completes alternating aging tests without manual supervision. A built-in USB data export port fully saves test curves and temperature-humidity records to meet data traceability requirements for factory audits and third-party testing. Integrated built-in chamber lamp, main power switch and emergency stop button deliver multi-layer safety protection for simple and safe operation.

Target long-tail search terms: Programmable high-low temperature humidity test chamber, laboratory constant temperature & humidity chamber with data export function, fully automatic alternating aging test machine

2. 304 Stainless Steel Sealed Inner Tank for Uniform Temperature & Humidity with Zero Test Error

The inner tank is integrally formed of corrosion-resistant 304 stainless steel, equipped with multi-layer hollow racks to hold batches of electronic chips, auto parts and new energy battery samples at the same time. Thickened high-elastic silicone sealing strips on the door effectively block internal and external air exchange, stably controlling temperature uniformity and humidity fluctuation inside the chamber to fully meet national standard test requirements and avoid test deviations caused by air leakage. It is a dedicated high-precision constant temperature & humidity chamber for reliability testing.

Target long-tail search terms: Constant temperature & humidity chamber with 304 stainless steel inner tank, temperature-locking humidity alternating test chamber, high-precision product aging test chamber

3. BTHC Balanced Temperature & Humidity Control System with Wide Temperature-Humidity Range for Full-Industry Testing

Adopting mature BTHC balanced temperature and humidity regulation technology and premium original compressors, the machine delivers stable and controllable temperature rise and fall rates. The standard temperature range covers -70℃ ~ +150℃ with adjustable humidity from 20% RH to 98% RH. It supports various environmental tests including humidity-heat aging, hot-cold cycling, moisture-proof weathering and accelerated high-low temperature aging, suitable for full-category product testing in electronics, automotive and new energy industries.

Target long-tail search terms: -70℃ ultra-low temperature constant temperature & humidity chamber, power battery humidity-heat cycle test machine, plastic high-low temperature weather resistance test chamber

4. Industrial Durable Structure Supporting 24/7 Non-Stop Factory Operation

The bottom is fitted with universal moving casters and adjustable support feet for easy equipment transfer and horizontal leveling. A built-in LED light inside the double-layer hollow observation window enables real-time sample viewing without opening the door. An independent heat dissipation duct is reserved on the machine body to prevent overheating during long-term continuous operation, ideal for mass continuous testing in factories.
