Altitude Temperature (& Humidity) Chamber

Custom Product

Overview of Equipment

With the proliferation of more diverse and portable electronic and electrical devices today, devices are being subject to use and storage in complex environments, and evaluation testing is required in those environments.
Combined pressure, temperature, and humidity environments can be reproduced to perform usage environment evaluation and storage evaluation at high altitude for electronic and electrical devices.
Furthermore, this chamber provides a testing environment under reduced pressure. It is perfect for the detection of malfunctions of automobiles for which more electronic components are used during driving at higher elevations and for the evaluation of components intended for use in aircraft.
On ESPEC's testing chamber, you can set the pressure up to an altitude of 45,000 meters, so you can evaluate operation at low-pressure, low-temperature highlands and evaluate air transport.

Temperature & humidity control range under atmospheric pressure

MZH-◯◯H-H Temperature and humidity control range under atmospheric pressure
MZH-◯◯H-H Atmospheric pressure and temperature and humidity control range under reduced pressure: Controllable range of vacuum-temperature and humidity, 93.3 ~ 70.9kPa (altitude 3,000m, 10,000ft); * This model supports tests which require the control of temperature and humidity under reduced pressure. We can make suggestions to meet the requirements of customers. Please contact our sales representatives.

Option

· The addition of the wall surface control function (3 kPa -1.1 kPa) can expand the temperature/pressure control range to an equivalent altitude of 78,000 ft - 100,000 ft.
