KJ-HW-50L Environmental Test Chamber

KJ-HW-50L is a programmable constant temperature and humidity chamber designed for R&D samples, routine laboratory validation, and small-batch environmental reliability testing. With a BTHC balanced temperature-humidity control system and P.I.D.-driven SSR output, it can stably simulate high temperature/high humidity, high temperature/low humidity, low temperature/high humidity, low temperature/low humidity, and cyclic humidity-temperature conditions. It is well suited for electronics, plastics, coatings, automotive parts, medical packaging, and research applications. When your test requires both temperature and humidity control, this chamber is usually a better fit than a temperature-only chamber.
