Temperature / humidity / Vibration integrated test chambers

Product Usage ：LENPURE Lenpure CVTH Series vibration chambers offer rapid temperature change rates with combined temperature, humidity, and/or vibration environments. All models are designed for compatibility with your choice of electrodynamic or mechanical vibration systems. While each model is manufactured to standard designs, they may also be custom engineered to meet a wide range of stringent test requirements.The CVTH Series temperature/humidity and vibration chambers was originally designed to perform specific temperature, humidity, and vibration tests in order to improve the quality and reliability of military hardware and to conform with MIL-STD 781 and 883.Chambers may also be used as temperature cycling chambers without vibration utilizing a solid floor plug.
