Triplett ACDL200 Dual Input True RMS Datalogger
The Triplett ACDL200 provides dual-channel recording of TRMS voltage and current with flexible sampling. It supports 1 second to 24 hour intervals and stores up to 131,000 measurements per channel in dual-input mode or 256,000 in single-input mode. Min/Max recalls help identify peak conditions, and a 0.5″ jaw captures conductors without disassembly. Ideal for building diagnostics, panel studies, and energy audits where simultaneous voltage and current trends matter.
Triplett ACDL100 True RMS Datalogger
The ACDL100 offers single-channel TRMS monitoring for AC voltage (up to 600V) or current (up to 200A). It records with 1 second to 24 hour sampling and stores up to 100,000 measurements. Its compact design with a 0.5″ jaw makes it suitable for quick field checks, service panels, and energy audits where a reliable snapshot of a single channel is sufficient.
10A-6000A Portable Electric Energy Meter
This multi-function power quality analyzer measures currents and voltages across all three phases and neutral, delivering real-time RMS values. It also computes key electrical parameters such as power factor, real power, and reactive power. The device supports comprehensive monitoring of three-phase systems, helping identify phase imbalances, harmonic content, and overall system health in distribution panels and industrial plants.
Kethvoz Clamp Meter Data Logger
The Kethvoz 570SAPP supports TRMS measurements for voltage and current with a large 1000 A clamp. It features built-in Bluetooth for mobile data logging and export to txt or Excel formats. This makes it suitable for remote monitoring, troubleshooting in electrical installations, and field work where recording multiple data points over time is essential for analysis and reporting.
HUATO S220-T8 Eight Channel Data Logger
The HUATO S220-T8 offers eight thermocouple channels with Type K, J, E, T, N, S, R, and B sensors, supporting a temperature range from -200 to 1800°C. It includes external power and a NIST-traceable certificate option. This logger is ideal for processes requiring multi-point temperature monitoring, heat-mup, and quality assurance across industrial environments with high-precision needs.
Buying Guide: Key Purchase Considerations
- Channel requirements: Determine if you need single-channel, dual-channel, or multi-channel logging to match your monitoring goals.
- Measurement scope: Decide whether voltage, current, power quality, or temperature are the primary metrics to track.
- Sampling rate and duration: Consider required sampling intervals (seconds to hours) and total data capacity for your testing window.
- Sensor compatibility: Check jaw size for clamp meters and sensor types for thermocouple loggers to ensure proper integration with your equipment.
- Data accessibility: Prefer devices with straightforward data export (CSV, TXT, or Excel) and optional Bluetooth or USB interfaces for analysis.
- Calibration and accuracy: Look for True RMS measurements where applicable and any available NIST-traceable certificates for critical temperature data.
- Ease of use: Consider device form factor, display clarity, and whether software requires Windows or cross-platform support.
- Safety and compatibility: Confirm voltage/current ranges align with your system’s specifications and ensure safe handling in field environments.
