Routine maintenance helps to identify issues early on, preventing more extensive damage later. Regular cleaning of the chamber's interior and exterior keeps it in condition and improves its overall performance. The chamber's heating and cooling systems must be regularly checked, and the refrigerant level should be monitored. The chamber's sensors and recorders must be calibrated regularly to ensure readings are accurate. Air filters must be cleaned or replaced to avoid contamination. Proper cable management, sealing, and insulation are essential. OEM parts should be certified, and repairs should be done by trained technicians to prevent malfunctions and avoid invalidation of warrantees. As one of leading environmental test chamber suppliers offering ip67 test equipment, we have to stress that environmental test chamber maintenance and upkeep may have additional regulations based on industry standards and applications, and supplier manual guidelines should be followed.
