Product Overview & Applications
HM3020J SF6 Leak Tester is suitable for detecting sulfur hexafluoride (SF6) gas, C4F7N gas, or other halogen gases (such as fluorine, chlorine, bromine, iodine, and chloroform, Freon F11, F12, F13, F22, etc.). It is applicable to high-voltage switches, medium-voltage switchgear, and other electrical equipment; railway, chemical, electrical manufacturing, fire-fighting equipment, refrigeration industries, and atomic physics research departments.
Products features
1 High sensitivity, good stability, and rapid response.
2 Simple operation, convenient calibration, and accurate testing.
3 Manual and automatic calibration are both possible, facilitating calibration and adjustment.
4 The sensor is not poisoned and does not produce toxic gases.
5 Automatic sensor protection function and fault indication function.
6 The LCD screen simultaneously displays concentration and grid values, making readings convenient and accurate.
7 *Dual screens on the probe and main unit simultaneously display concentration and grid values.
8 Display mode can be set to display both concentration and grid values simultaneously or only the grid value.
9 *Calibration knobs or buttons ensure the instrument's sensitivity and accuracy.
10. Alarm points can be set arbitrarily within the measurement range, automatically generating audible and visual alarms.
11. The instrument's probe is equipped with a dustproof mesh, effectively preventing dust from entering and affecting instrument performance.
12. *Wi-Fi for wireless transmission and RS485 communication interface.
