With a true RMS capability, the Fluke 117 delivers accurate measurements even on non-linear loads, making it particularly useful for modern electrical systems.

In terms of specifications, it offers a decent measurement accuracy of +/-0.5%, which is suitable for most tasks. Its low input impedance helps eliminate false readings caused by ghost voltages, ensuring the reliability of measurements. The large LED backlight is a thoughtful addition, allowing you to work in dimly lit areas without straining your eyes.

The Fluke 117 is an excellent option for those who require precision and versatility in their measurements, particularly electricians and technicians. Its combination of features and dependable performance makes it a worthy investment.

The Fluke 17B+ Digital Multimeter is a reliable tool for those involved in electrical applications, offering a wide range of measurement capabilities. It accurately measures AC/DC voltage up to 1000V and current up to 10A, making it versatile for residential, commercial, and industrial settings. With a CAT III 600V safety rating, users can feel secure when working with electrical systems. The multimeter also includes features for measuring resistance, continuity, capacitance, and frequency, which are crucial for diagnosing and troubleshooting electrical issues.

A standout feature is its ability to test diodes and measure temperature up to 400°C, which is particularly useful for those monitoring heating and cooling systems. This makes the multimeter a flexible tool for various tasks beyond basic electrical measurements.

Weighing in at 450 grams, it might be heavier than some other models, which could be a consideration for portability. The device is battery-powered, so users will need to manage battery life and replacements, but this is generally standard for digital multimeters. Its dimensions make it a bit bulkier, which might not be ideal for those needing to work in confined spaces.

The Fluke 17B+ is well-suited for professionals and enthusiasts who need a robust and versatile multimeter for a range of electrical measurement tasks, provided they are comfortable with its weight and potential space requirements.

The Klein Tools MM420 digital multimeter offers a solid mix of features suitable for general electrical work and DIY enthusiasts. It can measure AC/DC voltage up to 600V and current up to 10A, covering most common tasks. The inclusion of True RMS (TRMS) technology means it provides more accurate readings on complex signals compared to simpler meters. Auto-ranging makes it easier to use by automatically selecting the correct range, so you don’t have to guess.

The meter also measures resistance up to 50 MΩ and offers extra tests like temperature, capacitance, frequency, duty cycle, continuity, and diode checks, making it quite versatile. Klein Tools designs their meters with safe and standard input impedance suitable for most electronics work. Safety is enhanced with Lead-Alert, which lights up to confirm your test leads are correctly placed, helping avoid measurement errors or hazards. The backlit LCD is great for working in dim areas. Convenience features like lead holders, a kickstand, and optional magnetic hanger improve usability during hands-free tasks.

Powered by included AAA batteries and weighing about 14.5 ounces, the meter might feel a bit bulky compared to more compact models. It is suitable for electricians, technicians, and serious hobbyists who want a reliable, easy-to-use multimeter with plenty of functions without stepping into professional-grade pricing or complexity. Its safety ratings make it ideal for most common uses, though it may not be intended for very high-energy industrial environments.
