For maintenance and inspection of the main circuit! Used by about 50 companies nationwide (such as power plants, substations, heavy electrical manufacturers, etc.)! Direct reading of resistance value, high precision, durable, and inexpensive!
This is a device for measuring the contact resistance of the main contact part of electrical switching devices, consisting of a current generator and a digital voltmeter. *Since 2022, a new type of case has been introduced. The appearance is slightly different from the conventional case. Please refer to the photos and dimensions in the catalog.

| Model number | overview |
|---|---|
| ST-10 | 10A current type. The resistance value cannot be read directly. It is even cheaper than the ST-10A. Set the desired current value, switch the display to voltage, and read the voltage value to check the resistance value. The accuracy, precision, and stability are the same as the ST-10A. |
| ST-102A | 100A current type. The resistance value can be read directly. It is the best seller. |
| ST-102 | 100A current type. The resistance value cannot be read directly. It is even cheaper than the ST-102A. Set the desired current value, switch the display to voltage, and read the voltage value to check the resistance value. The accuracy, precision, and stability are the same as the ST-102A. |
