UT622A Digital Inductance LCR Meter

Precision LCR Meter – Up to 0.1% high accuracy measurements, the unit mainly measures inductance (L), capacitance (C), resistance (R) of components, also measures impedance (Z), dissipation factor (D), quality factor (Q), angle phase (θ), and ESR.
Accurate Measurement – Selectable 4 test frequencies of 100Hz, 120Hz, 1kHz, and 10kHz. Selectable 3 test levels of 0.1V, 0.3V, and 1V. Selectable tolerance of 1%, 5%, 10%, and 20%. Able to select parallel or series increasing accuracy of in-circuit testing. Auto-off in 5min, 15min(default), 30min, or 60min are selectable.
3 Measurement Speeds – Slow(2 times per second), medium(5 times per seconds) and fast(20 times per second).
Tolerance Comparison – Equipped with audible/visual alarm, and counter features for tolerance fail/pass test.
Data Logger – The average, maximum, minimum value can be recorded via data logging mode.
Zeroing – Open/short zeroing eliminates connection errors, deliver more accurate measurement each times.
USB to PC – Transfer data to the PC/Laptop through a USB port, and exports to image file(jpg.), Excel and PDF report is available.
Portable – High resolution LCD with 5 digit display, lightweight, portable, and battery operated.
Applied in the product development, incoming inspections, or production line testing.

    Suitable for use everywhere from in the house to restaurants, offices and industrial areas, the UT337A measures the exact value of carbon monoxide (CO) present in the air. Featuring a built-in sensor integrated into the top of the unit, the UT337A measures CO content from 0-1000ppm with accuracy of ±5% (5ppm) and resolution of 1ppm. The sensor is also designed to adjust rapidly to changes, ensuring you always get a stable, accurate reading. When CO levels exceed a certain threshold, the UT337A will alert the user by using a combination of audible and LED light indicators. The alarm is configurable to the user’s specification and it is also possible to use this meter to calculate temperature values.
