Multimeter devices, including digital multimeters and multimeter clamps, are essential for measuring various electrical properties such as voltage, current, and resistance. Digital multimeters, like our M890C, M-890D, M-890F, and M-890G models, offer precise readings and user-friendly features, making them ideal for both professional and DIY use. Multimeter clamps, such as the Digital Micro Multimeter Meter DT9300C, provide additional functionality with features like non-contact measurement, a data hold function for easy reading, and the ability to measure temperature, making them invaluable for HVAC applications. Both devices ensure accurate and reliable performance, catering to various electrical and refrigeration needs.
