HM3030 SF6 Gas density relay calibrator

SF6 density relay meter, this is a kind of intelligent & automatic checking instrument of SF6 density

◆ can automatically check pointer type and electronic type density circuit breaker.
◆ shows the current pressure, corresponding pressure and environment temperature at 20℃,to solve the problem of SF6 density relay on-site check


HM3030 SF6 Gas density relay calibrator, this is a kind of intelligent & automatic checking instrument of SF6 density. The instrument adopts the single cycle instruction of microcomputer technology, which the operating speed is 10 times ordinary single chip. It can be calibrated at field to check SF6 density circuit breaker of pointer contact output and intelligent current output, it uses interrupt mode to capture circuit breaker density at real-time. The instrument has the characters of SF6 standard conversion under any ressure  environment, portable ,auto calibration of SF6 density and pressure.

In a closed container, SF6 gas pressure under certain temperature can represent SF6 gas density. It is usually used as SF6 gas pressure standard value at 20℃. Under different environment temperature, measured pressure values are to be converted into its corresponding to value at 20℃, it can be used to judge the performance of SF6 density circuit breaker.

The SF6 Gas density relay calibrator’s measurement is automatically finished, so it is convenient and simple.



1.The meter adopt analog digital mixed single cycle high speed microcontroller technology, it has rich and powerful resources, strong data processing ability,  it has the characters of simple outer-ring circuits, good stability and accuracy because it built in A/D, D/A, reference voltage, analog amplifier integrated.

2.The instrument can automatically check pointer type and electronic type density circuit breaker.

3.Density relay 1 ~ 3 group contacts of the initial state is arbitrary form (closed or open always), it can simultaneously measure response value and recovery value of 1 ~ 3 group contacts , so the instrument can auto measure all kinds of circuit breaker.

4.320*240 large screen liquid crystal display, simple and convenient to use.

5.It shows the current pressure, corresponding pressure and environment temperature at 20℃,to solve the problem of SF6 density relay on-site check.

Auto test process, to avoid operation by mistake.

7. 100 groups measured dates storage, every measurement can be traced.

8. RS-232 interface data upload PC , automatic generation test data form.

9.Normal temperature pressure and density under any environment temperature can be calibrated.

Advantage quick joints, convenient connection and small leakage.

Built in clock, which can be corrected at any time.

Self checking function. Calibration can be corrected after using, to ensure calibration precision.

13.High precision pressure sensor and advanced magnetic fluid technology.

14.Built-in high capacity battery, LCD display quantity of electricity, convenient on-site check.
