1. High testing accuracy: The core components use imported components, which have high integration, accuracy, repeatability, and reliability. Due to its use of high-speed sampling A/D, it can not only measure density relays with conventional action values, but also density relays with particularly small action values.
2. Highly intelligent: The calibration process does not require a constant temperature chamber, and SF6 gas density relays and pressure gauges can be calibrated within any effective temperature range. By using pressure and temperature dynamic compensation algorithms, the pressure is automatically converted to the equivalent pressure value at 20 ℃, and the current pressure at the temperature and the equivalent pressure at 20 ℃ are displayed, completely solving the problem of difficult on-site calibration of SF6 gas density relays.
3. Powerful features:
① Density relays can measure different pressure types, and density relays can measure both relative pressure and absolute pressure.
② The initial state of the 1-3 sets of contacts of the density relay is in any form (normally open or normally closed), and the up and down values of the 1-3 sets of contacts can be measured simultaneously, such as alarm, lockout, overvoltage, etc. Therefore, this instrument can adapt to the fully automatic calibration of all new and old density relays.
③ Simultaneously displaying the current pressure and ambient temperature during measurement solves the problem of on-site calibration of density relays.
4. Friendly human-machine interface: Equipped with a 7-inch high-definition full-color touch screen, it is easy to operate, has a beautiful interface, and all parameters and states are clear at a glance.
5. Complete set of transition joints: This product is a portable instrument equipped with various types of transition joints. Most types of switch density relays can be verified on-site without disassembly, making it the best choice for SF6 density relay calibration.
6. Low gas consumption: During the calibration process, the gas consumption is minimal, SF6 gas is not wasted, the testing cost is low, and there is no pollution.
7. Support for data storage: The instrument is equipped with a large capacity memory, which can instantly save test results. It also has the function of saving power outage data, allowing for real-time querying and printing of historical test data.
8. Support printing: After the test is completed, all relevant test results can be printed immediately, and historical data can also be printed for analysis.
9. USB flash drive transfer: supports USB flash drive transfer of historical test data, which can be read through the matching upper computer software, making the operation simple and fast.
10. Convenient to carry: The instrument is powered by a large capacity lithium battery, without the need for AC power, solving the problem of difficult outdoor power retrieval. Moreover, after the instrument is fully charged, it can work for a long time or be plugged into a charger to work simultaneously.
11. Powerful PC software: Equipped with powerful PC upper computer application software, it is easy to operate and can display data, save in Word format, print and generate complete test reports, making it convenient for centralized data management.
