Constant Temperature Humidity Test Chamber
The Constant Temperature Humidity Test Chamber from Zonsky Instrument Co, Ltd is designed to meet the performance criteria of GB5170.2, 3, 5, 6-95 and environmental testing standards including GB 2423.1-89, GB 2423.2-89, GB/T 2423.3-93, and GB/T 2423.4-93. It operates within a temperature range of -40°C to 150°C with a fluctuation of ±0.5°C and deviation of ±2°C. Humidity control spans 20% to 98% RH with ±3% fluctuation and deviation, ensuring precise environmental simulation for product reliability testing.
The inner chamber is constructed from SUS #304 stainless steel, 1.0 mm thick, with an outer shell of atomized or baked varnish stainless steel. Insulation combines hard polyurethane foam and glass wool to minimize thermal loss. The air circulation system uses a 90 W motor with a stainless steel extended axle and a SIRCCO FAN multi-leaf fan for uniform airflow. The refrigeration system employs a French-imported fully enclosed compressor with R404A refrigerant, a fin-type condenser, and a capacity-controlled expansion system for stable operation under continuous load.
This chamber is commonly used by manufacturers of electronics, automotive components, and pharmaceuticals to validate product performance under extreme environmental stress. Buyers typically require compliance with IEC 68-2 series standards for certification testing. The unit is supplied with a single left-hinged door featuring a 270 x 360 x 40 mm triple-layer vacuum window and a SUS #304 embedded handle. Trade terms are typically FOB Guangzhou, with lead time confirmed upon order. Packaging includes wooden crate reinforcement for ocean freight.

Sourcing Constant Temperature Humidity Test Chamber from Zonsky Instrument Co, Ltd - China Import Guide
Before ordering, verify the chamber’s compliance with GB5170 and IEC 68-2 series standards through documentation provided by the supplier. Confirm that the inner chamber material is genuine SUS #304 stainless steel with a thickness of 1.0 mm, and request material certification. Ensure the humidity and temperature sensors are calibrated and traceable to national standards. Avoid units without test reports for deviation and fluctuation under load conditions.
Confirm the Incoterms offered - typically FOB Guangzhou - and whether the supplier handles export documentation. Lead time is not stated; buyers should request a production timeline and buffer for customs clearance. Payment terms are commonly 30% advance, 70% before shipment. Verify if the unit is packaged in a wooden crate with shock-absorbing foam and if crating meets ISPM-15 for international shipping.
On delivery, inspect for physical damage and verify all accessories are present: control panel, power cord, user manual, and calibration certificate. Conduct a 24-hour dry run at 25°C and 60% RH to test stability. Use a secondary data logger to cross-check temperature and humidity readings. Retain all documentation for warranty claims and future audits. If used for regulatory testing, arrange third-party validation before deployment.
