Product Description

​​​​​​​The UNI-T UT191T Digital Multimeter True 6kV IP65 is a professional model in the UT191 series of industrial-grade digital multimeters, featuring temperature measurement capabilities and designed for industrial users operating in harsh environments. This product integrates a 6000-count True RMS measurement engine for accurate acquisition of nonlinear signals. It boasts an IP65 protection rating (fully dustproof and water-resistant) and can withstand drops from a height of 2 meters, making it suitable for electrical testing and troubleshooting in harsh environments such as petrochemical, aviation, and high-voltage electrical systems. Its safety rating conforms to the CAT III 600V standard, with a built-in full-function false reading protection mechanism that can withstand 6kV lightning pulse voltage surges. Compared to the UT191E model in the same series, the UT191T Digital Multimeter True 6kV IP65 additionally features K-type thermocouple temperature measurement with a resolution of 0.1℃, allowing users to perform temperature monitoring without carrying an additional temperature instrument.

This product has obtained four international certifications: CE (EMC, LVD, RoHS), UKCA, GS (AfPS GS 2014:01), and cTUVus, and complies with multiple IEC/EN/UL safety standards. With its robust industrial-grade construction, comprehensive measurement functions, and professional-grade protection design, the UT191T has become a reliable tool of choice for electrical engineers, HVAC technicians, and industrial maintenance personnel in harsh field environments.

The UT191 series is designed "for industrial environments, not just specifications." From input protection circuitry to mechanical structure, every aspect is engineered to suit real-world usage scenarios: three-stage overvoltage protection (transistor clamping + TVS diode + PTC thermistor) ensures reliability under sudden voltage surges; waterproof rings are installed at the joints of the top and bottom covers and the battery cover; the fixing nuts use copper inlays instead of self-tapping screws to prevent breakage of the fixing posts in case of drops. The PCB uses double-sided copper plating, the input trace width is ≥1.2mm, and the solder joints are potted with epoxy resin to improve vibration resistance.

  • The significance of True RMS: Ordinary average response multimeters assume the measured signal is a standard sine wave. When measuring non-sinusoidal signals generated by inverters, LED drivers, switching power supplies, etc., the error can be as high as 15%. The UT191T's True RMS engine can directly calculate the effective value of the signal, ensuring accurate readings under various waveforms.
  • Applications of LPF low-pass filtering: The PWM signal output by a variable frequency drive (VFD) contains a large number of high-order harmonics, and the voltage values ​​read by a conventional multimeter are often artificially high. The LPF function of the UT191T can filter out high-frequency noise components, so that the reading reflects the effective value of the fundamental frequency, which is crucial for the diagnosis of motor drive systems.

  • LoZ Low Impedance Input: In long-distance cables or capacitive loads, high-impedance multimeters are prone to detecting "ghost voltage"—a false induced potential generated by capacitive coupling. LoZ mode eliminates this induced voltage by providing a low-impedance input path, thus obtaining the true line voltage. Allow the device to cool down for 1 minute after using the LoZ function.

The UT191 series is UNI-T's professional-grade digital multimeter product line for industrial users. Positioned as a replacement for traditional consumer-grade multimeters, it meets the rigid requirements of industrial environments for high strength, waterproof and dustproof performance, and high safety levels. This series adopts a dual-slope A/D converter architecture and features a 6000-count display, achieving performance.

The UT191 series includes two models: UT191E and UT191T. Both are identical in their core electrical measurement functions; the key differences are as follows:

FAQs:

  • What is the purpose of LoZ's low impedance input function?​​​​​​​​​​​​​

A: Eliminates ghost voltage,Provides extremely low input impedance (approximately 3kΩ) during measurement,Prevents interference from induced voltages generated by adjacent live conductors,Ensures accurate determination of whether a line is truly energized.

  • What is the low-pass filtering function of LPF suitable for?

A: Specifically designed for testing variable frequency drive (VFD) speed control drives, it can filter out high-frequency switching noise and accurately measure the true sinusoidal voltage and frequency of the VFD output.

  • What is its security protection level?

A: Meets CAT III 600V safety standards, supports full-function false test protection, can withstand up to 6kV lightning pulse voltage impact, and is equipped with a high-capacity, high-breaking-capacity fuse.

  • Why can't the current meter read a value?

A: It is highly likely that the internal fuse has burned out. Misusing the current setting to measure the voltage will cause the protective fuse to burn out. It is necessary to replace it with a general-purpose fuse of the same specification with a high breaking capacity.

  • What to do if a multimeter won't turn on?

A: Check if the 9V battery inside the back cover is depleted. This meter has an automatic shutdown (APO) function. If it has not been used for a long time, you need to rotate the dial to wake it up again.

  • What should be noted about the watch leads and waterproof gaskets?

A: After replacing the battery or fuse, the screws must be tightened to ensure the rubber waterproof seal is in the correct position; otherwise, the IP65 protection level will be lost.
