Sheesh I sound like a FLUKE salesperson, but I'm not. One of the most important things with electrical testers is that they are simple and safe and fast. You really don't want anything complex, that just increases the chance of a mistake and literally death. You unpack this and it's ready to go. No buttons to press, no on switch, no range, nothing. It's just there and ready. It works out whether you need voltage or continuity testing and you are always safe. There is nothing for you to do other than use it and take readings. There are no switches. It indicates voltage if there is one and does a continuity test if there is no voltage present. There is an instruction sheet, or in fact a huge wad of them, since they did one in every conceivable language and decided to include every single one in every single box, lol, but really one quick read and you realise there is nothing to learn lol. My only reservation is that I would have liked it to have a crocodile clip for the negative lead. It does have fat probe contacts that screw over the small ones. I would just like to point out that Fluke seemed to have changed the continuity test because one reviewer complains there is no beep for one second. That's no longer true. The unit beeps immediately and is a slow beep for continuity and a very fast beep for voltage. One thing that is really handy is that it beeps when in contact with 240V even when the -ve is not connected to anything. The probe cover also has a tab on it for depressing the earth shield in standard UK sockets. That is really handy. The probes are also spaced so they fit directly in to a UK mains socket. Again, very handy. Typical Fluke, a very well thought-out piece of kit. They are expensive but really they are just so well thought-out that they are worth it. Review: Great bit of kit - Had one before so this is a replacement quick delivery and all worked when unpacked ## Features - Designed according to IEC EN 61243-3: 2014 to verify the absence of voltage – even with discharged batteries. - CAT IV 600 V, CAT III 690 V safety rating - Single-pole phase test offers fast identification of live conductors. - Backlit graduated scale and backlit indicators - Continuity test—visual results ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CSRYG8A | | Best Sellers Rank | 23,320 in DIY & Tools ( See Top 100 in DIY & Tools ) 29 in Voltage Testers | | Brand | Fluke | | Colour | Yellow | | Country Of Origin | United Kingdom | | Customer Reviews | 4.7 4.7 out of 5 stars (1,247) | | Global Trade Identification Number | 00095969599672, 05053252199799 | | Included Components | rubber tip protector, 2x GS38 Probe Tip Sheath, 2x 4 mm ∅ Probe Extensions | | Item Dimensions | 23 x 6.5 x 3.8 centimetres | | Item Type Name | T90 Voltage Tester | | Item Weight | 180 Grams | | Manufacturer | Fluke | | Maximum Operating Voltage | 690 Volts | | Measurement Type | Voltmeter, Ohmmeter | | Minimum Operating Voltage | 12 Volts | | Model Number | FLUKE-T90 | | Power Source | Corded Electric | | Product Warranty | 2 year manufacturer | | Specification Met | UL, CE, IEC 61010-1, NIST traceable, RoHS compliant | | Style Name | Single | | UPC | 095969599672 175421464790 175421464783 768724933591 | | Unit Count | 1 Tester | ## Product Details - **Brand:** Fluke - **Colour:** Yellow - **Item weight:** 180 Grams - **Power source:** Corded Electric - **Style:** Single ## Images ![T90 Basic Voltage and Continuity Tester - Image 1](https://m.media-amazon.com/images/I/518Kf3PE+ZL.jpg) ## Questions & Answers **Q: Does this tester Fluke T90 test 3 phase rotation ?** A: Hi The Fluke T90 does NOT test 3 phase rotation - the other models (T110/T130/T150) all test phase rotation from 100v to 690v. Fluke also do a dedicated phase rotation meter - model number 9040 and a phase and motor rotation meter 9062. Regards, Steve Testermans **Q: What is the size of the tips of the test leads? is it possible to cover them?** A: Good morningI'm unsure what size the probes are but the Fluke T90 is supplied with tip covers to ensur ethat no more than 2mm of the tip is shown to fully comply with GS38 guide lines.ThanksGareth Phipps - Technical Support **Q: With the probe cover on, can someone please tell me the overall length from the end of the probe cover down to the strain relief?** A: 225 to the bottom of the casing **Q: Will it show me how to use it for beginers** A: this is a good basic voltage & continuity tester and with a little basic electrical knowledge is easy to use ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple, Safe and very well thought-out. *by M***! on 12 June 2018* T90 Very well made and as per usual with FLUKE extremely well designed for intuitive and safe operation.

I needed to locate a 12v DC source and this helped immensely. I also used it to test the continuity of some audio cables, and again it worked perfectly. The packaging is good, the manual gives clear instructions (15 different languages). This tester was ridiculously easy to use, there's no buttons to press on the T90, I made sure, I carried out a self test, before using it (touch and hold the two probe tips together). The build quality and design was second to none. With the T90, you get two extra tips, which can be stored in the cap so you don't loose them. In operation, this tester was so simple to use. After the self test, I just probed the opposite ends of two audio cables for a continuity test, if the circuit was complete, then an indicator would light up and an audible beep would occur. In the car test, I put the black probe on an earthed source, and probed each cable until the 12v DC icon lit up, with an audible beep. So in conclusion, if you're after a reliable voltage and continuity tester that wont break the bank, this is the one. The Fluke brand is synonymous with quality. ## Frequently Bought Together - Fluke T90 Voltage & Continuity Tester, Yellow - Fluke 1AC II VoltAlert Non-Contact Voltage Tester, Pocket-Sized, 90-1000V AC, Audible Beeper, 2 Year Warranty, CAT IV Rating, Packaging May Vary - Fluke T6-1000 PRO Electrical Tester --- ## 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.kr/products/48236175-t90-basic-voltage-and-continuity-tester](https://www.desertcart.kr/products/48236175-t90-basic-voltage-and-continuity-tester) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-26*
