Metravi - Clamp-on Earth and Ground Resistance Tester with Bluetooth - CET-03B
Descriptions
The Metravi CET-03B Clamp-on Earth and Ground Resistance Tester with Bluetooth is widely used in earth resistance measurement and loop resistance measurement in electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.
When measuring the grounding system of the loop circuit, there is no need to disconnect the grounding down lead or auxiliary earth electrode, and it enables safe and fast testing.
The tester can measure ground faults that cannot be measured by traditional methods, and can be applied to the site which cannot be measured by traditional methods, as earth resistance tester measures the comprehensive value of the grounding body resistance and the grounding lead resistance.
The Metravi CET-03B Clamp-on Earth and Ground Resistance Tester with Bluetooth has a long jaw which is suitable for the site of flat steel grounding. It can also measure leakage current grounding system and the neutral current.
Features
- Avoids long self-test waiting after power-on, and enters the test interface immediately after power-on.
- No relay self-test and adopts advanced algorithms and digital integrated processing technology.
- No bulky problem of old products and is portable & handheld.
