Featuring a crisp 128x64 LCD, rapid 2-second testing, and ultra-low 20nA power consumption with automatic shutdown, it offers precise measurements from 30pF to 100mF capacitance and up to 50MΩ resistance. Powered by a 9V battery and housed in a protective case, it’s the essential tool for engineers and tech-savvy professionals seeking quick, reliable diagnostics. ## Description Specifications: Material: PCB Display: 128 x 64 LCD Normal Testing Speed: 2 seconds Shutdown Current: 20nA Capacitor Measure Range: 25pf -100000uf Inductance Measure Range: 0.01mh-20H Resistance Measure Range: 0.1ohm resolution, maximum 50M ohm Features: 1. Support boot voltage detection function 2. Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, triodes, resistors, and capacitors. Automatically testing the component leads and displaying them on the LCD 3. The forward bias voltage of the emitter transistor can be determined by detecting the amplification factor and base number of a transistor, a MOSFET protection diode, and the like 4. Measure gate threshold voltage and gate capacitance MOSFET 5. The display uses 12864 lcd LCD (128 * 64 characters) 6. High test speed, valid component test: In 2 seconds (except in larger capacitors, large capacitance measurement also takes a long time, the measurement time in 1 minute is normal) 7. One-button operation, power-on test. 8. Power Consumption Shutdown Mode: Less than 20 nA 9. Automatic shutdown function can avoid unnecessary waste, save battery energy and improve battery life. Note: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter. Package included: 1 x Transistor Tester with case Review: Handy tester. - Handy device for a quick test of components. Review: Excellent quality. - It works very well. A little not accurate, but components are very well recognized ! I upgraded it with a step up Buck DC converter to have it works with a 5 DC USB (to 9 DC). Happy to help if you need details. ## Features - Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other components. - Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage. - Digital 128*64 LCD display for easy readings, can display measured data and graphics. - Measure capacitanceCan measure capacitance of 30pF-100mF , resolution 1pF. - Use 9V battery(not included), can also use DC power(DC 6.8-12V). Automatic shutdown, shutdown current is only about 20nA. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08K2Z5BGR | | Brand | ALMOCN | | Colour | Multicolor | | Customer Reviews | 4.4 out of 5 stars 69 Reviews | | Item Weight | 0.23 Kilograms | | Item weight | 0.23 Kilograms | | Manufacturer | ALMOCN | | Manufacturer Part Number | DA09251 | | Measurement Type | LCR Meter | | Min.

A little not accurate, but components are very well recognized ! I upgraded it with a step up Buck DC converter to have it works with a 5 DC USB (to 9 DC). Happy to help if you need details. ### ⭐⭐⭐⭐ Techie's Dream Come True *by M***K on 29 July 2024* Imagine blending precision with convenience. This little gizmo has been my go-to for testing all sorts of components around the house. From capacitors in my old record deck to the resistors in my daughter's science project, it does the job efficiently. The Zero Insertion Force socket's a nice touch, though be mindful of the battery life, keep a spare PP3 handy or go for an external PSU. Putting the case together is a tad fiddly but manageable, and stick-on feet wouldn't go amiss to save my desk from vicious scratches. Despite these quirks, this thing's a champ at identifying components, plucking out dodgy capacitors, and even showing neat pictograms of components on the display. It's not just a gadget; it’s practically a family member in our home's tech cabinet! For the thrifty engineer or the DIY enthusiast, this is hard to beat. --- ## 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.co/products/301154027-lcr-t4-mega328-transistor-tester-resistance-capacitance-diode-triode-capacitor](https://www.desertcart.co/products/301154027-lcr-t4-mega328-transistor-tester-resistance-capacitance-diode-triode-capacitor) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-07-21*
