Product Introduction
The HIOKI 3144-20 Noise Detector is a professional instrument designed for identifying and analyzing noise interference in communication lines. Utilizing non-contact voltage sensor technology, it provides accurate measurements without direct electrical contact. The device features a compact design with clear LCD display and intuitive operation interface, making it suitable for field technicians. With its wide frequency coverage and multi-band analysis capability, it has become an essential tool for maintaining signal integrity in telecom and power systems.68
Key Features
This detector offers seven fixed frequency bands for detailed noise spectrum analysis, ranging from 500Hz to 30MHz. The built-in memory stores up to 64,000 measurement records with timestamp, while the USB interface enables easy data transfer to PCs. Unique waveform monitoring function allows users to audibly detect signal envelopes through headphones. The included clamp sensor can measure insulated wires up to 17mm in diameter, suitable for most cable types.610
Technical Specifications
Measurement ranges include ×1 range (0dBV to -30dBV) and ×10 range (-20dBV to -50dBV) with 2.5dBV resolution. The compact body (62×158×40mm) weighs only 260g excluding batteries, powered by six AA batteries providing 5 hours continuous operation. Operating temperature range covers 0°C to 40°C. The horizontal meter display provides instant visual feedback on noise levels across different frequency bands.810
超聲波測厚儀補(bǔ)充說明
采用超聲波脈沖反射原理，適用于金屬、塑料、陶瓷等多種材料的厚度測量。典型應(yīng)用包括管道壁厚檢測、壓力容器腐蝕監(jiān)測等，測量范圍0.7-250mm，分辨率0.01mm。設(shè)備具有聲速校準(zhǔn)功能，可通過已知厚度試塊反算材料聲速。輕量化設(shè)計(jì)（245g）和IP防護(hù)等級使其適合石油化工、船舶制造等復(fù)雜工業(yè)環(huán)境。17
Ultrasonic Thickness Gauge Addendum
Operating on ultrasonic pulse-echo principle, this gauge measures material thickness without damaging test pieces. It supports various materials including metals, plastics and ceramics, with measuring range of 0.7-250mm and 0.01mm resolution. The velocity calibration function allows users to calculate material-specific sound speed using reference samples. Weighing only 245g with ergonomic design, it s widely used in petrochemical plants and shipyards for corrosion monitoring.17
