KJ-HW-150L Environmental Test Chamber

KJ-HW-150L is part of the KJ-HW programmable constant temperature and humidity test chamber series. The KJ-HW programmable constant temperature and humidity test chamber series, also known as a high-low temperature and damp heat cycling chamber, uses a balanced temperature and humidity control system (BTHC) with P.I.D.-controlled SSR output to keep heating and humidification balanced with thermal and moisture loss for stable long-term operation. The series can simulate high temperature/high humidity, high temperature/low humidity, low temperature/high humidity, and low temperature/low humidity environments for reliability testing in aerospace, electronics, electrical appliances, petrochemical, coatings, plastics, telecommunications, medical, pharmaceutical, university, and research applications.
