LORDERAN Damp Heat Test Chamber with Water Recirculation for 85/85 & 95/95 Testing, 60–100°C, 80–98%RH, 316 Stainless Steel Interior

A high temperature, high humidity test chamber built for one job and built to do it for weeks: damp-heat endurance testing. It holds 60 to 100 °C at 80 to 98 %RH, the region where Double 85 (85 °C / 85 %RH) and Double 95 (95 °C / 95 %RH) testing live. A SUS316 stainless steel interior, forced-air circulation and Pt100 sensors keep conditions steady hour after hour. Four sizes from 150 to 1000 L.

Made for Double 85 and Double 95 Double 85 and Double 95 are the reliability and accelerated-ageing tests the electronics, photovoltaic and automotive parts industries rely on. Heat speeds up chemistry; humidity drives moisture into seals, laminates and packages. Together they reveal in weeks the corrosion, delamination and insulation failures that would take years in the field. This chamber is dedicated to that window, held without a break. 5060708090100110707580859095100Temperature (°C)Relative humidity (%RH)60 °C · 98 %100 °C · 98 %60 °C · 80 %100 °C · 80 %Double 8585 °C · 85 %RHDouble 9595 °C · 95 %RHWORKING ENVELOPE1000 habout six weeks,non-stopA typical damp-heat endurance test 5060708090100110707580859095100Temperature (°C)Relative humidity (%RH)60 °C · 98 %100 °C · 98 %60 °C · 80 %100 °C · 80 %Double 8585 °C · 85 %RHDouble 9595 °C · 95 %RHWORKING ENVELOPE1000 habout six weeks,non-stopA typical damp-heat endurance test 85/85 · 95/95°C / %RH, both inside the envelope ≤ ±3 %RHhumidity deviation ≤ 2 °Ctemperature uniformity 0.01 °Csetting resolution Specifications Models HWS-150H, HWS-250H, HWS-500H and HWS-1000H. 220 V or 110 V.

It is assembled on site, commissioned and accepted at your facility. Questions buyers ask Straight answers before you order. What is a Double 85 test? A damp-heat test held at 85 °C and 85 %RH, commonly for 1000 hours, used for electronic components, photovoltaic modules and other products that must resist heat and moisture. It sits well inside this chamber’s 60–100 °C, 80–98 %RH envelope. How is it different from a standard climate chamber? It is dedicated to high heat and high humidity. Instead of covering low temperatures and low humidity, it focuses on holding 60 to 100 °C at 80 to 98 %RH steadily for very long tests, with a SUS316 interior for corrosion resistance. Can it test below 60 °C or under 80 %RH? No. For wider ranges, choose a LORDERAN climate chamber, which covers −40 or −70 °C to 150 °C and 20 to 98 %RH. What is a Double 95 test? A more severe damp-heat test held at 95 °C and 95 %RH. Like Double 85, it is a standard reliability and accelerated-ageing test in electronics, photovoltaics and automotive parts, and it is inside this chamber’s envelope. How often do I need to add water? Rarely. The circulating water-evaporation humidifier has a water recirculation system, with water-level control and low-water protection, and Φ8 mm inlet and outlet ports. Keep a floor drain nearby. Which standards is it built to? GB10586 and GB/T 2423.3, IEC 60068-2-78, IEC 60068-2-30, IEC 60068-3, JESD22-A101, IEC 61215 / IEC 61730 and the relevant clauses of MIL-STD-810.
