Overview
The ANENG SZ304 is a compact digital multimeter aimed at DIY enthusiasts, homeowners, and entry-level technicians who need a reliable tool for everyday electrical measurements. It is widely available on marketplaces such as AliExpress, often at a budget-friendly price. This review examines its features, performance, pricing, and user experiences to help you decide if it fits your needs.
What the ANENG SZ304 Offers
The SZ304 is designed to measure a range of electrical parameters, including:
- DC and AC voltage (up to 1000V DC and 750V AC)
- DC and AC current
- Resistance
- Capacitance
- Frequency
- Diode and triode testing
- Continuity
- Non-contact voltage (NCV) detection
- Battery testing for common 1.5V, 3V, 9V, and 12V cells
It features a 2000-count digital display, auto-ranging for simplified operation, and a data hold function to freeze readings. The device is powered by two AAA batteries (included) and has an auto power-off after about 15 minutes of inactivity. Physically, it measures 188mm x 91mm x 38mm and weighs 158g, with an ABS plastic casing and a built-in kickstand for hands-free use.
Pricing and Availability
The ANENG SZ304 is typically priced around $8 to $15, depending on the seller and current promotions. For instance, one source listed it at $8.04 after a 48% discount from $15.33. It is commonly sold on AliExpress, with shipping times of 10-20 business days for standard delivery. Some sellers offer free returns within 30 days if the item is defective or not as described. Prices can vary between different listings and configurations, so it's worth comparing options.
Performance and User Experiences
Users report that the SZ304 offers good value for its price. Many appreciate its fast response time, clear display, and the inclusion of features like NCV and capacitance testing that are often found on more expensive meters. The auto shut-off is praised for saving battery life. However, some users note that the device is bulkier than expected and not pocket-friendly. Accuracy is generally considered adequate for DIY and light professional work, though it is not intended for laboratory-grade precision. The sampling rate of about 2 times per second is slower than some high-end models, but acceptable for most tasks.
