Multimeter UNI-T UT18B MAX

Product detailed description

We offer a 3-year warranty on this product.

Digital Multimeters UT18B MAX is a reliable True-RMS digital multimeter. The multimeter is designed to withstand interference and can filter out interference from carrier frequency overlaid sinusoidal or variable voltage distortion signals, and is capable of measuring the output voltage of a variable frequency drive. In the DC/AC voltage mode, the instrument can perform frequency and duty cycle measurement. The UT18B MAX has a temperature measurement function with a resolution of 0.1 C. The LED test function allows the UT18B MAX to test LEDs with voltages up to 12 V without the need to determine polarity.

The True RMS UT15B/17B/18B MAX Series multimeters feature a compact and portable design, fast response, strong EMC interference protection, and come with standard gold-plated test leads and gold-plated test leads with fine terminations.They also feature 1000V full-range input protection, making them an ideal tool for electronic and electrical engineering applications.
