YM-3U23B Differential Pressure Leak Detector Instructions
This series of instruments uses a self-developed dedicated control board for control and calculation. Coupled with high-precision sensors within the instrument, it calculates the leakage of the product and compares it with the set upper and lower limits to determine whether the tested product is qualified.
◇Features high precision, fast response, and a simple and clear interface;
◇Equipped with a volume test program, it can automatically calculate the volume of the product, reducing measurement errors caused by manual estimation;
◇Uses a self-developed control board and dedicated control and test program, with high precision and strong anti-interference ability;
◇Provides a selection of various pressure and leakage rate units:
◇High-definition large screen, intuitive curve, making the interface simple and clear;
◇Equipped with a report page, which can statistically analyze and save the test results, storing up to 100,000 sets of data
◇The instrument is equipped with a USB interface for downloading and storing test results;
◇Supports Chinese/English interfaces to suit different customer groups;
◇Equipped with a 485 interface supporting Modbus protocol, allowing for remote control, setting, and monitoring of the test;
◇Equipped with an internal filter, greatly extending the service life of the instrument;
◇Rich external control interfaces allow the instrument to be embedded in other systems to meet the needs of automated control;
