Precision Digital Multimeter Tailored for High-Precision Industrial Measurements, with True RMS and High Reliability

Product Description

The UT15B MAX/UT17B MAX/UT18B MAX are highly reliable True RMS digital multimeters with a built-in VFD anti-interference start-up mode that filters out carrier frequency interference superimposed on a sinusoidal waveform or a variety of aberrant voltage signals to stabilize the measurement of inverter output voltage. The UT17B MAX and UT18B MAX can be switched to frequency and duty cycle measurements in DC/AC mode, and the UT18B MAX is equipped with a temperature measurement function with a 0.1°C graduation rate, while the UT18B MAX has an LED measurement function that can measure up to 12V LEDs without distinguishing between positive and negative polarity. The full-featured UT18B MAX/UT18B MAX products are fully protected against mismeasurement of up to 30kVA of energy, and alarms for misplaced input holes of current gears, ensuring safer and more secure operation for users; the products have obtained CE and cETLus certificates according to the CAT III 600V safety level.
