    Bluetooth Clamp AmmeterInstall the "Intelligent Meter" APP on your mobile phone/tablet to connect easily and automatically. The app displays volts amperes ohms measurements on a current clamp meter. In addition to continuously monitoring readings using Bluetooth functionality, you can log data at programmable intervals, export data and graphs.
  • Auto Range Digital Clamp MeterThis TRMS digital clamp meter can accurately measure AC and DC current up to 1000A with 0.1A sensitivity by clip-on clamp. The auto-ranging clamp meter can also measure AC and DC voltage, resistance, capacitance, frequency, temperature, diode and continuity test, etc.
  • Multifunctional AC DC AmmeterVoltmeter current clamp has multiple functions. This AC/DC Current Clamp Meter has a large LCD backlit display for easy reading even in the dark; data hold function; low battery indication; temperature measurement (C/F); high and low voltage alarm settings; Data is zeroed for accurate readings.
  • High Precision Clamp AmmeterThe clamp ammeter has high resolution up to 1A, you can use the clamp meter to measure DC and AC current. The HP-570T-APP ammeter can be used to check battery chargers, solar panels, inverters and auto mechanics etc. Easy to use and perfect for safely resolving your automotive or electrical issues.
  • AC Current Measurement & Safety FirstYou cannot use the AC clamp on any meter to bypass the entire wire, but you must bypass one of the 3 wires inside. Otherwise, the AC ammeter will show a reading of zero amps. This clamp current ammeter conforms to the safety standard CAT 1000V or CAT 600V, and the full range has overload protection.
