USB rechargeable and backed by 2 years warranty plus lifetime support, it’s the ultimate tool for on-the-go diagnostics and flawless SMD testing. ## Description This Smart Tweezers ST5S kit includes: - ST52SAD Smart Tweezers unit - Calibration Certificate - Swiss-made straight test leads - Custom carrying case - Micro USB cable for charging from a USB port Review: Great aid for repair - I'm using it primarily while working on prototypes of industrial automation control devices - the instrument works exactly as described, I had no any glitches or malfunctions yet. Great aid for repair, building or tweaking up boards with small SMD components (those seemingly gold plated tips it comes with are easily landing on 0402 footprint components and are of good quality overall - the "shorting" resistance is less then 40 mOhm) - saves alot of time in comparison to frustrating process to do that holding probes of conventional multimeter as chopsticks. Fast and accurate (compared with readouts of benchtop Fluke multimeter) readings, crisp graphic OLED display, plenty of measurement modes and presets (including, for the instance, caps ESR, diode voltage drop (useful for transistors as well) measurement, etc. The thing like these tweezers becomes exceptionally useful for finding right replacement components to scavenge from scrapped boards for resuscitation of device being repaired. The interface is convenient and reasonably intuitive for such small instrument - the brief look at supplied "menu tree" card and you got it (e.g., the "joystick control" has direct shortcuts to common measuring modes and parameters setup. Review: Excellent acquisition. - I am very satisfied with the purchase, very useful and very precise ## Features - Precision LCR Meter, 0.1% Accuracy, ideal for SMD, calibrated, certificate included - Automated component identification. Automatic and manual C, R, L, Z, ESR modes - ClearValue OLED Display, Swiss-made 24K Gold-plated Test Leads - desertcart Special: Portable and clam shell cases, spare test leads are included - 2 Years Warranty and Lifetime support. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0068QJ5Z6 | | Best Sellers Rank | #280,079 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #34 in LCR Meters | | Brand Name | Smart Tweezers | | Color | Black | | Customer Reviews | 4.7 4.7 out of 5 stars (64) | | Included Components | Portable, clamshell cases, spare Swiss-made test leads, calibration certificate | | Manufacturer | Advance Devices, Inc. | | Measurement Type | LCR Meter | | Model | ST5S | | Part Number | ST52SAD | | Power Source | Battery Powered | | Specification Met | Calibrated, 0.1% Accuracy | | Style Name | Professional | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Smart Tweezers - **Color:** Black - **Power Source:** Battery Powered - **Specification Met:** Calibrated, 0.1% Accuracy - **Style:** Professional ## Images ![ST5S Professional LCR Meter/ESR Meter with Spare Test Leads and Pocket Case - Image 1](https://m.media-amazon.com/images/I/61KMYSXqJSL.jpg) ## Questions & Answers **Q: What are the component value ranges this can work with?** A: Smart Tweezers SpecificationsPhysical Specifications Operating Temperature: 0 °C to +50 °C Storage Temperature: -40 °C to +70 °C Relative Humidity: 0 % to 90 % (0 °C to 35 °C) 0 % to 70 % (35 °C to 55 °C) Altitude Operating: 0-2000 meters Battery Type: 3.7 V LiPO rechargeable 150 mAh Typical Charge Time: 2.5 Hours Electromagnetic Compatibility (EMC): Susceptibility and Emission: CE 89/336, FCC 15 part B Size: 14.0 x 2.5 x 3.0 cm (3.94 x 0.9 x 1.5 in) Weight: 53 grams (0.11lb) Warranty: 1 year Basic Specifications Measured Parameters: L, C, R, ESR, D, Q Measuring Frequencies: 100 Hz, 120 Hz, 1 kHz, 10 kHz Measurement rate: 1 time per second Resistance: 0.05 Ohms to 9.9 MOhms Capacitance: 0.5 pF to 4,999 µF Inductance: 0.5 µH to 999 mH Dissipation Factor: 0.001 to 1000 Accuracy SpecificationsAccuracy is specified at 18°C to 28°C (64°F to 82°F), with relative humidity to 90%.

Test leads are Swiss-made. **Q: Hello, Does this item come with a calibration certificate? Could i request for that for my order?** A: I beleive it does but it has been almost a year since we have ordered so I can't be 100% sure. Sorry..... **Q: This is an expensive but quality device. Can it handle in-circuit caps (discharged), and is there a good manual for non-engineers?** A: Hello: I bought my unit about 4 yrs ago. there was not a good manual. I am guessing you can go on line and find a manual. I would not recommend this for a non engineer. It can be used for in circuit cap testing, however it might not be accurate depending on the type of circuit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great aid for repair *by V***B on June 5, 2018* I'm using it primarily while working on prototypes of industrial automation control devices - the instrument works exactly as described, I had no any glitches or malfunctions yet.

They also shipped me a new version of the tweezers that do not have this problem and have some other improvements. I am back up and running, and using the new tweezers. Thanks to Advance Devices for the great service, have no reservations, if something goes wrong, Advance Devices will take care of you. Original review: I design high performance analog circuitry for a living and have worked designing electronics for 20 years now. I work on the highest performance circuitry in the world. I've recommended these tweezers to friends in the industry, and right now I am wondering if I steered others in the wrong direction. I loved these tweezers for the first 6 months, really makse testing surface mount components fast and easy. But when I went to use the tweezers recently, they would not turn on. I checked the cables and charger, tried a few different options, other device that uses the same charging port charge just fine. I get nothing on the display, just completely dead. More than a little disappointing given I have only had them 6 months. The company has no information on service, warranty or otherwise. I sent an e-mail, and got no response. Maybe they are small and on vacation? I am going to try and call, but thus far it seems the customer service is non-existent from the manufacturer, and appears that it is going to be a pain for me. Unless/until the company responds, I will be giving this product 1 star and I do not recommend that you spend close to $300 on this item when service is so questionable. Hopefully the company won't continue to be MIA and will stand behind the product they are selling. I will update my review with new information. ## Frequently Bought Together - Smart Tweezers ST5S Professional LCR Meter/ESR Meter with Spare Test Leads and Pocket Case - FNIRSI LCR-ST1 10KHz LCR Meter Tweezer, Mini Smart SMD Tester, ESR Meter, Multimeter, Capacitance Inductance Continuity Diode Tester, Auto Component Recognition Electronic Component Analyze --- ## 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.sg/products/7016535-st5s-professional-lcr-meter-esr-meter-with-spare-test-leads](https://www.desertcart.sg/products/7016535-st5s-professional-lcr-meter-esr-meter-with-spare-test-leads) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-16*
