UNI‑T UT373 Mini Non‑Contact Laser Tachometer Digital RPM Meter 10‑99999 RPM Speed Counter LCD Backlight

UNI‑T UT373 Mini Non‑Contact Laser TachometerThe UT373 is a compact digital laser tachometer adopting photosensitive diode & laser tube sensor , performing non‑contact photoelectric speed measurement for rotating equipment. No need direct contact with the tested object, avoid interfering rotation status.Main FeaturesNon‑contact Laser Photoelectric Type : Laser beam detects reflective mark on rotating surface, safe for high‑speed motor, fan, wheel and spindle.High‑precision MeasurementRPM Range: 10.0‑9999.9 RPM (resolution 0.1RPM); 10000‑99999 RPM (resolution 1RPM) Accuracy: ±(0.04%+2)Counting measurement: 0‑99999 countConvenient Practical Functions Data Hold: Freeze measured value on screen for easy reading MAX / MIN value capture: Record peak & minimum rotating speed LCD backlight: Clear reading under dim environmentAuto‑shutdown: Save battery power for long‑time standby Real‑time refresh rate: 1‑7 seconds (1s refresh for speed over 120RPM)Human‑oriented DesignSmall handheld body: Lightweight for one‑hand operationMeasuring distance: 50mm‑200mm; Measuring angle＜30°Low‑battery reminder, overload indication, laser‑on indicatorIP65 protection rating, passed 1‑meter drop test SpecificationsItemParameterRPM Measurement10.0~9999.9RPM(0.1RPM);10000~99999RPM(1RPM)Counting Range0‑99999 countRefresh Rate1‑7s (＞120RPM: 1s)SensorPhotodiode + Laser tubeMeasuring Distance50‑200mmPower Supply3×AAA 1.5V batteriesContinuous Working Time12 hoursDimension183.8×56×34mmWeight85g (exclude battery)Working Environment0℃‑50℃, ≤80%RH Package Includes1 × UT373 Mini Laser Tachometer1 × Reflective PaperUser Manual> > Application scenarios: Motor speed inspection, fan blade rotation, machinery spindle, DIY equipment maintenance, industrial workshop testing.
