Product features
German flow display interface (labor-saving observation, multi parameter display on the same screen)
Enclosed watch head packaging (electronic components isolated from outside dust interference, protection is improved)
With three electrode support, can be a variety of medium measurement, impact resistance, corrosion resistance
Adopt polishing process, long term use can not drop the paint
Anti-jamming circuit design anti-jamming, anti-wave leakage, range value is more stable
