UT385 Laser Power Meter

 is a professional optical measurement instrument designed to measure the output power of laser devices accurately. Engineers, laboratory technicians, and electronics professionals commonly use this device to test laser equipment in research laboratories, optical communication systems, industrial laser machines, and educational environments. As a result, the UT385 Laser Power Meter helps ensure that laser systems operate within safe and specified power levels.

Moreover, the UT385 Laser Power Meter uses a high-precision optical sensor that detects laser radiation and converts it into an electrical signal for accurate power measurement. The instrument processes this signal and displays the laser power value clearly on the digital LCD screen. Therefore, technicians can quickly evaluate laser output performance during equipment calibration or testing.

In addition, the device supports measurement of laser wavelengths within the range of 400 nm to 1100 nm, covering most commonly used visible and near-infrared laser sources. Because of this wide wavelength compatibility, the UT385 Laser Power Meter can measure power from red lasers, green lasers, infrared laser diodes, and many other optical sources used in industrial and scientific applications.

Furthermore, the instrument offers a laser power measurement range from 0 to 40 mW, which makes it suitable for measuring low-power laser modules commonly used in electronics, optical experiments, and laser pointer devices. The device provides high measurement resolution and accuracy, enabling reliable testing results for laboratory and technical applications.

Another useful feature of the UT385 Laser Power Meter is its data hold function, which allows users to freeze the current measurement reading for easier documentation. In addition, the device includes a backlit LCD display, ensuring clear visibility of readings even in low-light environments.

The device also includes practical functions such as automatic power-off and compact portable design, which improve usability during field testing and laboratory measurements. Because of its reliable optical sensor and simple operation, the UT385 Laser Power Meter is widely used in laser equipment testing, optical laboratory experiments, laser diode measurement, educational training, and optical device calibration.
