Digitalni multimetar – unimer UNI-T UT18B.
Digital multimeters UT18B MAX is a reliable True-RMS type digital multimeter. Designed to withstand interference, the multimeter can filter out interference from the carrier frequency superimposed by a sine wave signal or a variable voltage distortion signal, and is capable of measuring the output voltage of a variable frequency drive. In DC/AC voltage mode, the instrument can perform frequency and duty cycle measurements. 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 a voltage of up to 12 V without the need to determine the polarity.
The UT15B/17B/18B MAX Series True RMS Multimeters feature a compact and portable design, fast response, strong protection against EMC interference, and come with standard gold-plated test leads and gold-plated fine-ended test leads. they are also equipped with 1000V input protection throughout, making them an ideal tool for electronic and electrical engineers. Certificates: CE, UKCA, cETLus, REACH, RoHS
