Portable Wireless HV Clamp Current Meter GF2011 Live Line Measuring Tool

 Field power inspection often requires moving between scattered towers, remote mountain lines and crowded substation yards, making lightweight, all-in-one testing equipment a top priority for maintenance teams. Our GF2011 portable wireless HV clamp meter is built for full mobility, perfectly matching single-person field live line measurement workflows.

The complete kit weighs only 2.5kg with all accessories packed inside a compact storage case, easy to carry in work trucks or backpacks for long-distance patrol tasks. The segmented 5m extendable insulation rod can be split into short sections for effortless transport, featuring 100kV AC insulation strength to isolate operators from energized lines up to 69kV. Its 50mm large clamp jaw fits most overhead single cables, delivering ultra-wide measuring coverage from tiny 0.00mA leakage signals to 1200A heavy load current with 0.01mA high resolution and consistent ±1% measurement accuracy.

Equipped with barrier-penetrating 30m wireless transmission, the handheld receiver displays real-time readings far away from dangerous live wires without cutting power supply. The backlit 4-digit LCD guarantees clear data viewing under dim twilight or shaded substation environments. Practical built-in functions include peak value lock, data hold and storage for up to 99 groups of test records, supporting manual primary and secondary loop current ratio calculation for transformer diagnosis. The anti-drip meter body and weather-resistant insulation rod stand steady in temperatures ranging from -25°C to 40°C, resisting moisture, high heat and accidental impacts during rough outdoor use. It delivers 10 hours of continuous operation with standard alkaline batteries, paired with low-battery warning and 15-minute auto shutoff to avoid unnecessary power waste. Fully compliant with global IEC safety and EMC standards, this tool serves power distribution firms, mining electrical departments, property maintenance crews and power anti-theft inspection teams worldwide.

GF438II Basic Electrical Data Statistics & Automatic Logging Function

 The GF438II handheld Class A power quality analyzer embeds an independent statistical calculation module that continuously computes real-time, maximum, minimum and average values of core electrical indicators throughout the whole monitoring cycle, covering voltage, current, frequency, active/reactive power and power factor across all four voltage and four current channels. Unlike ordinary testers that only display instantaneous readings, it automatically accumulates statistical data without manual trigger, enabling engineers to quickly grasp load fluctuation ranges without post-processing on a PC.

Users can freely customize logging cycles from short second-level sampling to long-hour intervals to match different field test scenarios. All statistical datasets are timestamped and saved to the built-in 32G TF card synchronously, supporting long unattended recording lasting multiple days. The on-device statistical dashboard arranges all calculated values in intuitive tabular layout, and supports quick screen scrolling to compare peak and valley data of each phase, simplifying on-site preliminary evaluation of load stability.

Its logging system runs parallel with other test modes including harmonic analysis and flicker detection, so basic statistical records will not be interrupted when switching measurement functions. After field work completes, all stored statistical logs can be exported via USB drive and imported into GFUVEPQA PC software for data sorting, comparative analysis and standardized report generation. Equipped with a long-lasting rechargeable battery and compact lightweight body, it is well-suited for regular power inspection of factories, commercial buildings, new energy power stations and municipal power supply lines.

GF438II Long-Term Trend Recording & PST/PLT Flicker Measurement

 Built around IEC 61000-4-15 flicker international standards, the GF438II handheld power quality analyzer independently calculates short-term PST (10-minute) and long-term PLT (2-hour) flicker values for three-phase and neutral circuits, eliminating manual timing and calculation work for inspectors. It continuously captures voltage fluctuation data, generates intuitive flicker trend curves, and automatically marks time nodes where flicker exceeds standard limits for rapid grid interference source identification.

Its advanced long-term trend logging engine supports custom sampling intervals ranging from seconds to hours, capable of continuously storing up to 600 types of electrical indicators in the built-in 32G TF storage for weeks of unattended monitoring. All tracked metrics include voltage/current RMS, unbalance ratio, harmonic distortion, power values and flicker data, which are rendered into continuous trend charts with zoom and cursor tools for later data review. The system automatically retains complete timestamp labels for every record, fully meeting EN50160 grid compliance audit requirements.

Distinct from basic testers that separate flicker testing and trend storage, this unit synchronizes flicker sampling and long-term data recording in one single run without repeated test setup. The flexible 4-channel voltage and 4-channel current input design supports simultaneous flicker monitoring across multiple load branches, ideal for field audits of manufacturing workshops, photovoltaic combiner boxes and municipal power supply lines. After on-site testing, all trend and flicker datasets can be exported via USB to the matching GFUVEPQA PC software to generate standardized power quality compliance reports with embedded flicker trend graphs.
