MS-401SF6 gas density relay calibrator

The instrument's main function is to measure the alarm value, lockout value, alarm recovery value, and lockout recovery value of SF6 gas density relays. The measurement process can be performed with single or double lockout measurements.  The instrument also has the function of calibrating pressure gauges at room temperature and at 20°C.
1. Simple operation: All testing processes are completed automatically by the instrument without manual intervention, avoiding cumbersome manual gas circuit adjustment operations.
2. Convenient testing: This product is a portable instrument equipped with various types of transition connectors, allowing on-site calibration of most types of switch density relays without disassembly.
3. Highly intelligent: The calibration process does not require a constant temperature chamber, allowing calibration of SF6 gas density relays and pressure gauges within any effective temperature range. Using a dynamic pressure and temperature compensation algorithm, it automatically completes pressure measurement and 20°C value conversion, simultaneously displaying the pressure at the measured ambient temperature, the pressure at 20°C, and the ambient temperature, completely solving the problem of difficult on-site calibration of SF6 gas density relays.
4. Powerful functions: During SF6 gas density relay calibration, it simultaneously tests one set of alarm signals and two sets of lockout signals, and also has the function of calibrating pressure gauges at room temperature and at 20°C.
5. Safe and environmentally friendly: Nitrogen is used instead of SF6 during the calibration process, ensuring the safety of testing personnel, reducing testing costs, and preventing environmental pollution.
6. User-friendly interface: Large 320*240 dot matrix Chinese character graphic interface, clear and beautiful graphics, high-performance rotary mouse for convenient operation, and a built-in high-speed miniature thermal printer for instant printing of test data.
7. Data storage: The instrument can store up to 50 sets of test results and has a power-off data saving function, allowing for retrieval and printing of previous test results at any time.
8. USB transfer: Supports USB transfer of test data, which can be read by a PC, making operation simple and fast.
9. Powerful PC software: The PC application software is powerful and easy to operate, enabling data analysis, saving, printing, and generating complete test reports for convenient centralized data management.
