The utility model, which belongs to the technical field of the power detection auxiliary equipment, provides a density relay verification support comprising a support frame comprising at least three support rods. The bracket is located at the top end of the supporting frame and used for supporting the density relay; the bracket is located in the middle of the rear end of the bracket and used for enabling a connecting pipe of the density relay to extend out of the bracket. The density relay calibration support is simple in structure, reasonable in design and low in cost, calibration errors caused by artificial contact with equipment temperature sensing components are avoided, testers can accurately and rapidly read SF6 gas density relay values and measure contacts, calibration time is saved, time and labor are saved, and work efficiency is improved.
