2.9 In the calibration process, constant temperature chamber is not required,
and SF6 gas density relay and pressure gauge can be calibrated within any
effective temperature range.
2.10 Equipped with a variety of models of transition joints, most models of
switch density relay can be field verified without disassembly.
2.11 In the calibration process, the gas consumption is very little, SF6 gas is
not wasted, the test cost is low, and there is no pollution to the environment.
2.12 It has the function of modifying the system clock online.
2.13 It has the function of modifying system pressure on line and can be
corrected on site.
2.14 The core components are imported components with reliable
performance.
2.15 It can test one set of alarm signals and two sets of locking signals at the
same time.
2.16 This product is a portable tool, easy to use and reliable, is the best choice
for SF6 density relay calibration.
