Product feature and application

Dual-station automatic tripping: Support testing 2 pieces at one time. Each circuit monitors leakage current independently; single circuit breakdown or over-limit will trip automatically without affecting other channels.
Dry type testing without water injection: Adopt steel beads inside boots instead of traditional water filling, avoid damp inner lining trouble and improve testing efficiency and tool service life.
Lithium battery independent power supply: Leakage current sampling and tripping mechanism powered by built-in lithium battery with real-time power percentage display, realizing complete high-low voltage isolation.
High-bright LED display: Dual-channel leakage current displayed clearly; tripping current value can be set precisely via buttons.
Special customized fixture: Equipped with stainless steel grounding tray for insulation boots and dedicated container for insulation gloves, easy installation and stable test performance.

FAQ

1)Can this device be used for on-site testing without a fixed power supply

Yes. The device's pressure-resistant bracket is powered by a DC 12V lithium battery, which supports on-site testing without a fixed power supply, perfectly adapting to the mobile testing needs of small and medium-sized scenarios such as mining teams and construction sites.

2)How to deal with the situation that the lithium battery power is insufficient during on-site testing?

It is recommended to carry a backup lithium battery for replacement during on-site testing. At the same time, the device has a real-time power percentage display, which can remind you to charge or replace the battery in advance to avoid affecting the testing progress.

3)Is it necessary to have professional operation experience to use this device?

No. The device is equipped with a high-bright LED display and simple button operation. The tripping current can be set with one key, and no professional and complicated training is required, which is suitable for on-site operators to use quickly.
