| The CHT3540/A/B high accuracy DC low resistance meter is Hope Science & Technology’s most feature product for ultra-low-resistance tests in cable, materials and shunt industry. This new low resistance tester gives the highest accuracy and stability in the industry, the minimum resolution is up to 0.01uΩ. Using pulse forward and reverse current test mode, CHT3540A/B greatly reduces the large test error due to the heating in the process. The latest model CHT3540B has the calculating the resistivity function and its optional infrared thermometer can be used for non-contact temperature compensation. |
