Mô tả

The WIKA model 612.20 capsule pressure gauge is designed for very low pressure and vacuum measurement, utilizing a proven capsule measuring element to detect even minimal pressure changes with high accuracy. Featuring a stainless steel case and a copper alloy measuring system, it offers robust construction and reliable long-term performance. Front zero adjustment allows easy on-site calibration. With a wide selection of low pressure ranges and units such as mbar, kPa, and inH₂O, the 612.20 is ideal for medical technology, vacuum applications, environmental monitoring, laboratories, filter monitoring, and ventilation systems, providing dependable and precise low-pressure measurement.
