BTMETER AC/DC 1000A Clamp Multimeter
The 570T-APP model from BTMETER combines a clamp-on meter with broad measurement ranges and a built-in data logger. It supports AC and DC current up to 1000A, and voltage up to 1000V, with resistance, capacitance, frequency, and temperature measurements. A hall-effect clamp sensor provides precise amperage readings when testing multiple wires in a single clamp, though users should clamp the LIVE conductor for accuracy. The device can log data to a connected phone or tablet, enabling automatic graphing and easy sharing in Excel or TXT formats for diagnostics and reporting.
Kethvoz Clamp Meter Digital Multimeter
The Kethvoz 570SAPP offers true RMS measurements across voltage and current with a 6000-count display. It features a Bluetooth data-logging capability that exports Max/Min/Average values to a companion app, enabling remote monitoring and data export in TXT or Excel formats. The meter handles DC and AC currents up to 1000A, along with resistance, capacitance, frequency, and temperature measurements. A 45mm jaw simplifies clamping around thick wires, and the device emphasizes app-based data management for troubleshooting and record-keeping in HVAC and electrical work.
OWON CMS061 3-in-1 Bluetooth Clamp Meter
OWON’s CMS061 combines a 600A AC/DC True RMS clamp meter with an oscilloscope and data logger. Real-time waveform analysis helps pinpoint issues in motors and power supplies, while Bluetooth connectivity with the i-Meter app enables wireless data logging, trend analysis, and remote operation. This 3-in-1 tool suits professionals who need an integrated measurement system that supports live monitoring and portable data storage for project documentation and service reports.
AIOMST 570T-APP Clamp Multimeter
AIOMST’s 570T-APP is a 1000A clamp-on meter with data-logging capabilities and Bluetooth connectivity. It measures AC/DC current up to 1000A, voltage up to 1000V, resistance up to 60MΩ, capacitance up to 200μF, and frequency up to 9.999 mHz. Temperature testing spans -4 to 1832°F. The unit emphasizes a sensitive clamp sensor and a 1.77-inch jaw, enabling non-contact testing of multiple wires. Data can be shared or exported to analysis tools via the companion app, supporting HVAC and electrical diagnostics in remote or confined spaces.
BTMETER BT-570S-APP Clamp Multimeter
The BT-570S-APP from BTMETER is a 6000-count true RMS clamp meter designed for accurate AC/DC voltage and current measurements, with a broad measurement range for resistance, capacitance, and frequency. Its smart-logging feature allows real-time data tracking via a dedicated app, enabling users to capture maximum, minimum, and average values, create graphs, and output data for documentation. The device also includes a safe clamping jaw designed for thick wires and features non-contact voltage detection for quick status checks.
Buying Guide
- Measurement ranges and true RMS: For accurate AC measurements, choose models labeled as true RMS and with wide current and voltage ranges suitable for your typical work environment.
- Data logging and export: Look for built-in data logging with app or PC export options (TXT, CSV, or Excel). This is essential for troubleshooting over time and creating service reports.
- Clamp jaw size and accessibility: A larger jaw (around 45mm) helps clamp around thick or bundled wires, but ensure it suits your breaker panel clearances and space constraints.
- Bluetooth vs. Wi-Fi: Bluetooth-enabled meters are great for proximity use with mobile apps. Consider models with reliable app ecosystems and cross-device data sharing for fieldwork.
- Safety and measurement integrity: Non-contact voltage detection and proper isolation are important. Ensure the device has over-voltage protection and clear instructions to avoid measurement errors (e.g., separating hot and neutral conductors when testing current).
- Temperature and specialty tests: If you work with HVAC or industrial equipment, consider meters that record temperature, frequency, and capacitance, plus alarms or thresholds for critical conditions.
- Platform compatibility: Check whether the app supports iOS and Android, and whether data can be exported to common formats for analysis in Excel or data visualization tools.
- Durability and usability: A readable display, intuitive controls, and robust build improve field reliability. Battery life and adjustable backlighting help in low-light environments.
When selecting a clamp meter with data logging, align the tool with your typical job profile: HVAC diagnostics, electrical panel troubleshooting, or industrial equipment monitoring. Consider whether you need real-time waveform analysis, mobile data logging, or cross-device data sharing to ensure efficient problem-solving and thorough documentation for client reports and compliance records.
