About This Instrument
The Vartech V 981+ is the most advanced instrument in the Vartech range — a portable bench-top True RMS digital multimeter that brings laboratory measurement capability out of the lab. With a 3.5" colour TFT dual display showing 30,000 counts, PC interface for data logging, frequency measurement up to 300 MHz, a built-in rechargeable battery with Type-C USB charging and advanced functions including data recording, math and Run/Stop — it is built for R&D engineers, laboratory technicians and serious test professionals who refuse to compromise.
Key Features
- 30,000-count 3.5" colour TFT dual display — simultaneously displays two measurement values (e.g., voltage and frequency) in high visibility; eliminates the need to switch between functions
- PC interface with data recording — log measurement data to a computer for analysis, reporting and quality documentation; essential for production testing and calibration records
- Frequency measurement up to 300 MHz — covers RF signals, telecommunications, high-frequency electronics and harmonic analysis far beyond any handheld multimeter
- Built-in rechargeable battery with Type-C USB charging — no disposable batteries; charge from any laptop, power bank or USB charger for truly portable bench-top use
- Math functions and Run/Stop — perform on-screen calculations, freeze a live measurement or capture data events without connecting to a computer
- True RMS auto-ranging from 300 mV to 1000 V DC and 750 V AC with 0.05% best accuracy — bench-top precision in measurement
- Temperature measurement from −40 °C to 1000 °C with 0.1 °C resolution — highest resolution temperature capability in the Vartech range
- Capacitance up to 300 mF and duty cycle up to 99.9% — the most comprehensive measurement specification in the Vartech multimeter lineup
