{"product_id":"kg-f-app-battery-coulometer-100a-high-precision-coulomb-meter","title":"Kg-f App Battery Coulometer 100a High Precision Coulomb Meter","description":"1. The 2.4-inch high-definition color screen, the color matching is beautiful and generous, and the font is larger and clearer;2. Provide a mobile phone APP, which connects to the meter via wireless Bluetooth to view data and set parameters;3. The mobile APP can view the real-time curve and historical curve of voltage and current, and historical data can be exported;4. The display and measurement module are connected through a 3Meter 4P co-directional telephone line, the longest can be extended to 30 meters, which is more convenient to install;5. Both shunts and screws are made of pure copper materials to minimize power consumption in standby mode;6. After configuring the relay by yourself, it can realize over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, and over-power protection.7. The mobile phone APP can upgrade the wireless firmware of the measurement module;8. The parameters of voltage, current and temperature can be calibrated by themselves;Product name: coulomb meterWorking voltage: 9~100vCapacity range: 0~99999AhWorking current: 7.5mAThe current after closed backlight: 3.5mAVoltage precision: 1%(1 C)Current precision: 1%(1 C)Capacity precision: 1%(1 C)Size: 79x43x27mmCut hole size: 76.5x39.5mmLCD size: 49x24mmWorking temperature: -10~65CelsiusWire length: 15cmColour:As shownMaterial:plasticPackage Contents:1 x Coulomb Meter(100A)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.","brand":"FR-YISHENG","offers":[{"title":"Default Title","offer_id":43921282302147,"sku":"FR-YISHENG-000975","price":1290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/4355\/1683\/files\/jpg_81a3c23e-78a5-4ea8-aac1-de6a5a714a05.jpg?v=1725714646","url":"https:\/\/wrsss.com\/products\/kg-f-app-battery-coulometer-100a-high-precision-coulomb-meter","provider":"Wrsss","version":"1.0","type":"link"}
