YLm series refrigerant pressure gauge

◆ Model: YLm60 YLm100 YLm150
◆ Application: This series of instruments are special instruments for detecting low temperature or special refrigerant medium, mainly used in air conditioning refrigerator, water chiller, air dryer or assembling refrigerant meter group system.
It can also make different refrigerant multi-labeling panels according to customers' requirements, and there are many kinds of caps and cases (Swiss style) for customers to choose.
Due to the optimized connector design and the special considerations in the selection of welding materials and pressure sensing components, this series of products has excellent characteristics of anti-leakage, anti-pressure pulse and anti-vibration, so the quality of the instrument is greatly improved, and the malfunction and loss of the refrigeration system due to product quality problems are eliminated.
