EziLab offers the Temperature and Humidity Test Chamber EZL-TH162, a 225 L environmental test chamber that spans -50°C to 180°C and 10% to 98% RH. It heats at 3°C to 5°C per minute and cools at 0.7°C to 1.2°C per minute, with 0.1°C resolution and humidity fluctuation within 1% RH. Pt100 sensors, stainless steel construction, silicone rubber door seals, anti-frost and anti-condensation protection, and a pressure relief balance port come standard. That wide window lets one thermal chamber run cold-start exposure, high-heat aging, and near-saturation damp heat cycles without moving samples between units. Engineers use it for product testing, quality assurance, and R&D, simulating conditions from arctic storage to tropical humidity, and the 225 L workspace holds component batches or small assemblies. Over-temperature protection and an audible alarm guard long runs in this humidity chamber. Aerospace suppliers qualify avionics and materials against extreme cold and heat, automotive teams validate sensors and connectors for cold-start and hot-soak conditions, and industrial electronics makers screen boards. Its test methods follow GB/T 2423 and GJB 150 procedures for compliance testing. It suits labs upgrading a climatic chamber. A -50C floor and 98% RH ceiling suit extreme profiles, so compare milder chambers on the Climate Test Chamber and Temperature and Humidity Test Chamber pages if your tests stay narrower.
