UNI-T UT61D+ 1000V True RMS Digital Multimeters

The UNI-T UT61D+ belongs to the UT61+ series of digital multimeters, built for high-precision measurement tasks and tough electrical work. It is a handheld instrument with rugged build quality, offering reliable functioning in field or workshop settings. It can measure both AC and DC voltages up to 1000 volts, which makes it suitable for both low-voltage electronics and high-voltage electrical installations. The display is large, bright, and supports a 6,000-count resolution, which ensures that smaller differences in readings are clearly shown.

Beyond basic voltage, it spans multiple measurement parameters such as current (also both AC and DC), resistance, capacitance, frequency, duty cycle, and temperature. Safety is emphasized: there are audible and visual alarms for detecting Non-Contact Voltage (NCV), protection of inputs, and warnings for high voltage/current or temperature. The user interface includes a backlight to help in low light conditions, data hold, USB communication for logging or transferring data, and analog bar display to give visual sense of measurement changes.

In terms of form and usability, the UT61D+ is somewhat bulky compared to pocket meters, but this contributes to its stability and durability. It is powered by AAA batteries (4 × 1.5V), making replacements easy in many locales. The test leads are gold-plated for better contact, and a temperature probe is included as part of its accessories. Overall, this multimeter is aimed at users who need accuracy, safety, and a wide range of measurement capabilities, with enough ruggedness to bear rougher handling and varied measurement environments.
