Featuring True-RMS technology, it ensures accurate readings on distorted waveforms and supports current, voltage, resistance, and continuity measurements. Its durable design withstands harsh environments and extreme temperatures, while compatibility with an optional flexible sensor expands its current measurement capacity up to 4199A, making it an indispensable tool for modern electrical diagnostics. ## Description The Hioki CM3289 True-RMS AC Clamp Meter is a True-RMS rectifying 1000A AC clamp meter that has been designed with a thin sensor to help you get into the tightest spaces. The compact profile allows you to quickly clamp wires in confined spaces, yielding outstanding ease of use. The CM3289 utilizes True-RMS measurement, which produces accurate display values even when measuring a distorted waveform, for example from an inverter-equipped device or switching power supply. When connected to an optional flexible current sensor (sold separately), the CM3289 can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires, around which it was not possible to apply a clamp-on sensor in the past.|The CM3289 delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument provides voltage measurement, continuity check, and resistance measurement functionality. Despite its thin, compact design, the CM3289 has a broad operating temperature range of -13°F to 149°F (-25 °C to 65 °C) and can withstand being dropped from a height of 1 meter onto concrete. It is engineered for use in tough environments. Review: Excelente - Excelente Review: 重宝しています - 一般のクランプ電流計に比べ、狭い電線・ケーブル間でも測定できます。さすがに漏れ電流などの微弱電流の測定はできませんが、試してみるとは60ｍA以上は正確な値が出るようなので、「漏れ電流は目安として測れる」と考え使用しており、大変重宝しています。軽いこともあり腰袋に放り込んで使っています。手放せません。 ## Features - Thin and compact sensor profile yields outstanding ease of use in tight and confined spaces - Performs current, voltage, and resistance measurements as well as continuity check - Capable of measuring even harmonic waveform components by using True-RMS method - Suitable for tough environments with broad operating temperature range of -13°F to 149°F (-25 °C to 65 °C) - Connects to CT6280 flexible sensor (sold separately) to measure up to 4199 A in thick or paired wires ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BHXV63Q | | Best Sellers Rank | 83,833 in DIY & Tools ( See Top 100 in DIY & Tools ) 136 in Voltage Testers | | Brand | Hioki | | Colour | Black | | Customer Reviews | 4.5 out of 5 stars 216 Reviews | | Item Dimensions | 18.1 x 5.7 x 1.6 centimetres | | Item Weight | 0.1 Kilograms | | Item dimensions L x W x H | 18.1 x 5.7 x 1.6 centimetres | | Item weight | 0.1 Kilograms | | Manufacturer | Hioki | | Manufacturer Part Number | CM3289 | | Measurement Type | Clamp Meter | | Model Number | CM3289 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | Ce, Cat II 600v, Cat III 300v, Cat III 600v, Cat IV 300v | | Style | Digital | | Style Name | Digital | | Unit Count | 1.0 count | | Upper Temperature Rating | 65 Degrees Celsius | ## Product Details - **Brand:** Hioki - **Power source:** Battery Powered - **Style:** Digital - **Colour:** Black - **Item weight:** 0.1 Kilograms ## Images ![Hioki CM3289 AC Clamp Meter True RMS - Image 1](https://m.media-amazon.com/images/I/71CrVlmVmKL.jpg) ![Hioki CM3289 AC Clamp Meter True RMS - Image 2](https://m.media-amazon.com/images/I/61m0MNtHwjL.jpg) ![Hioki CM3289 AC Clamp Meter True RMS - Image 3](https://m.media-amazon.com/images/I/91-wNUU2YdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente *by J***Z on 28 April 2025* Excelente ### ⭐⭐⭐⭐⭐ 重宝しています *by 桑***佑 on 25 June 2026* 一般のクランプ電流計に比べ、狭い電線・ケーブル間でも測定できます。さすがに漏れ電流などの微弱電流の測定はできませんが、試してみるとは60ｍA以上は正確な値が出るようなので、「漏れ電流は目安として測れる」と考え使用しており、大変重宝しています。軽いこともあり腰袋に放り込んで使っています。手放せません。 ### ⭐⭐⭐⭐⭐ Great product with fast shipping *by B***Z on 26 May 2024* Best price , fast shipping and exceptional customer service. ## Frequently Bought Together - Hioki CM3289 AC Clamp Meter True RMS - Hioki CT6280 AC Flexible Current Sensor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/548747626-hioki-cm3289-ac-clamp-meter-true-rms](https://www.desertcart.com.cy/products/548747626-hioki-cm3289-ac-clamp-meter-true-rms) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-18*
