Bench Top Digital Multimeter with PC Interface TRMS 30000 Counts

About.

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.

• 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
