Sau 5 năm vận hành, hệ thống điện mặt trời áp mái có thể vẫn hoạt động ổn định nhưng sản lượng không còn giống thời điểm mới lắp đặt. Mức suy giảm phụ thuộc vào tuổi thọ tấm pin, nhiệt độ, bức xạ, độ ẩm, bụi bẩn, dây dẫn, đầu nối và bộ biến tần.

# DIFFERENTIAL PRESSURE METERS FOR AHUs, FCUs, AND AIR DUCT SYSTEMS In an HVAC system, air does not move across different zones with the exact same pressure

Non-destructive ultrasonic testing enables tank wall thickness measurements in areas prone to wear, corrosion, or high stress. This method helps assess the service condition of tanks used to transport hazardous materials or waste.

Ultrasonic coating thickness measurement is a non-destructive method for measuring dry coatings on wood surfaces and various wood-based materials. For total coating thickness measurements, the PosiTector 200 B1 is a suitable choice. The PosiTector 200 B3 can measure both total thickness and up to three individual coating layers, while the PosiTector 200 C3 is designed for thicker coatings.

A paint thickness meter provides measurable readings across vehicle panels. Comparing nearby readings can reveal inconsistencies associated with repainting, filler, rust repair, or collision work.

Quality control for coated concrete starts with a sound, clean, suitably dry substrate and includes checking surface profile, climate, coating thickness, and adhesion.

Reliable pull-off adhesion testing depends on a sound adhesive-to-dolly bond. For the aluminum dollies evaluated, abrasion and removal of loose debris were the most influential preparation steps.

Non-destructive wire coating measurement relies on matching the gauge and calibration to the wire substrate and diameter, then checking coated parts against required thickness limits.

A non-destructive concrete moisture meter uses electrical impedance to compare near-surface moisture conditions across a slab. The PosiTest CMM provides multiple scales and modes for fast comparative checks.

Duplex systems pair a barrier coating with zinc protection. PosiTector 6000 FNDS measures the paint and zinc layers individually in a single reading by combining magnetic and eddy-current measurement principles.
