10 Best Auto Multimeters 2025 in the United States

The AstroAI Digital Clamp Meter Multimeter is a versatile tool designed to measure AC current, AC/DC voltage, resistance, capacitance, and more, making it suitable for both industrial and household electrical troubleshooting. One significant strength is its auto-ranging capability that simplifies the measurement process by automatically selecting the appropriate range. Additionally, the large jaw opening enables easy measurement of AC current without disrupting the circuit, which is particularly useful in tight spaces.

The inclusion of non-contact voltage testing with sound and light alarm enhances safety by allowing detection of live wires without physical contact. Features like data hold, max/min readings, auto shut-off, low battery indicator, and continuity buzzer add to its functionality and user convenience. Its LCD backlit screen and flashlight facilitate operation in low-light conditions, which is a thoughtful design aspect.

However, it does not support DC current measurement, which could be a limitation for users needing this function. The device meets environmental pollution degree 2 and overvoltage category III 600V safety standards, providing a reliable safety profile. With a compact and lightweight design, the AstroAI Clamp Meter is portable and easy to handle. Durability appears satisfactory with the robust build and safety considerations in place. For users needing a reliable, easy-to-use, and feature-rich multimeter for a variety of electrical measurements, this product is an excellent option. Those requiring DC current measurement might need an alternative model.

The Fluke 117 Digital Multimeter is a highly regarded tool for measuring various electrical parameters such as resistance, continuity, frequency, and capacitance. One of its standout features is the VoltAlert technology, which allows for non-contact voltage detection, making it safer and more convenient to use. It also has an AutoVolt function that automatically selects AC or DC voltage, simplifying the process for the user.

The large white LED backlight ensures that the display is easy to read, even in poorly lit conditions. Its True RMS capability means it provides accurate measurements even on non-linear loads, which is beneficial for more complex electrical systems. The low input impedance feature helps to prevent false readings caused by ghost voltage, enhancing its reliability.

Additionally, its operating temperature range and battery life of around 400 hours (without backlight) make it a durable choice for prolonged use in various environments. The product is battery-powered and comes with the necessary batteries included, so it’s ready to use right out of the box. However, with a weight of 550 grams, it may be slightly heavier to handle for some users. In terms of safety, the Fluke 117 meets IEC standards, offering peace of mind during use. On the downside, it is relatively more expensive than other multimeters in the market. Despite being on the pricier side, its high customer rating (4.8 out of 5 stars) reflects user satisfaction. The Fluke 117 is well-suited for professionals and enthusiasts who need a reliable, accurate, and feature-rich multimeter for various electrical tasks.
