BSIDE S10/S11 Smart Digital Multimeter — 9999 Counts, 3.5" LCD Display
Take the guesswork out of electrical diagnostics with the BSIDE S10/S11 Digital Multimeter. Engineered for hobbyists, electricians, and DIY enthusiasts alike, this ultra-thin, portable multimeter packs professional-grade measurement capabilities into a sleek, ergonomic body. Whether you're testing home wiring, troubleshooting electronics, or verifying circuit continuity, this meter delivers fast, accurate readings every time.
Why Choose the BSIDE S10/S11?
- 9999-Count High-Resolution Display: A bright 3.5-inch LCD screen provides crisp, easy-to-read results even in low-light conditions.
- AC & DC Voltage Measurement: Handles DC voltage from 0.8V–620V and AC voltage from 2.2V–620V with ±0.5% accuracy.
- Non-Contact Voltage (NCV) Detection: Built-in V-Alert feature sounds an audible buzzer to warn you of live voltage without touching the wire — an essential safety feature for any electrical work.
- Comprehensive Measurement Range: Measures resistance (1Ω–60MΩ), capacitance (1nF–99.99mF), frequency (1Hz–60KHz), duty cycle (0.1%–99.9%), and automatically identifies diodes under 3.0V.
- Continuity Testing with Audio Alert: Instantly confirms circuit continuity — the buzzer sounds when resistance drops below 30Ω, so you can work confidently without staring at the screen.
- Manual Range Mode: Stay in full control of your measurements with manual range selection — ideal for precise, repeatable testing.
- Ultra-Portable & Slim Design: The thin-profile body slips easily into a tool bag, pocket, or kit. The S11 model includes a protective shell and USB charging cable for rechargeable use.
- One-Button Operation: Simple, intuitive switching between measurement modes makes it beginner-friendly without sacrificing the depth professionals need.
- Makes a Great Gift: Attractive packaging and premium build quality make this an ideal present for makers, engineers, and DIYers.

Frequently Asked Questions
Q: What is the difference between the BSIDE S10 and S11 digital multimeter models?
A: Both the S10 and S11 are 9999-count smart digital multimeters with identical measurement capabilities. The key difference is power: the S10 uses 2×AAA batteries (not included), while the S11 features a built-in rechargeable Li-ion battery (800mAh) charged via the included USB cable. The S11 also comes with a protective shell for added durability on the job.
Q: Does this multimeter support non-contact voltage (NCV) detection?
A: Yes. The BSIDE S10/S11 includes a V-Alert NCV function that detects the presence of live AC voltage without requiring probe contact. When live voltage is detected, an audible buzzer and LCD bar indicator alert you immediately — making it a valuable safety tool for checking outlets, switches, and wiring.
Q: What types of measurements can this digital multimeter take?
A: This multimeter measures AC and DC voltage, resistance (Ohms), capacitance (Farads), frequency (Hz/KHz), duty cycle (%), and performs continuity and diode testing. It offers a comprehensive range suitable for home electrical DIY, electronics projects, automotive checks, and more.
Q: Is the display easy to read in different lighting conditions?
A: Yes. The 3.5-inch large LCD screen displays up to 9999 counts, providing high resolution and excellent readability. The clear digital display makes it easy to read measurements quickly, even when working in confined spaces or at varying angles.
