Suitable for

• Calibration and maintenance of industrial laser equipment
• Laboratory research and development involving light sources
• Quality control testing for laser modules
• Monitoring laser output stability over time
• Educational demonstrations in physics and optics

When it may not be suitable

The Uni-T UT385 is specifically calibrated for laser power measurement within the 0 µW to 39.99 mW range and is not intended for high-power industrial lasers exceeding this capacity. It is also not suitable for measuring non-laser light sources or for use in environments with extreme temperatures or high humidity levels that fall outside the specified operating range.

Key specifications

• Measurement range: 0 µW to 39.99 mW
• Wavelength range: 400 nm to 1100 nm
• Wavelength presets: 520 nm, 633 nm, 650 nm, 780 nm
• Sampling rate: 0.5 seconds
• Data storage: Up to 199 sets
• Display: 4-digit backlit LCD
• Power source: 9V battery
• Operating temperature: 0°C to 40°C

How to use

To begin using the device, insert the 9V battery into the compartment and connect the sensor probe to the main unit. Power on the meter and select the appropriate wavelength setting that matches your laser source using the dedicated selection buttons. Position the sensor directly in the path of the laser beam, ensuring it is perpendicular to the light for maximum accuracy. Observe the real-time readings on the LCD display. You may utilize the data logging function to save measurements for later analysis or set threshold alarms to receive alerts if the laser power deviates from your desired parameters.

What to consider before purchase

• Ensure your laser source falls within the 0 µW to 39.99 mW power range
• Verify that your laser wavelength is compatible with the 400–1100 nm detection range
• Check if the split-type sensor design meets your specific workspace requirements
• Confirm that the operating environment temperature and humidity are within the specified limits

Usage recommendations: Always ensure the laser beam is safely contained and directed at the sensor to prevent accidental exposure. Regularly calibrate the device if used in critical industrial applications and store the unit in its protective case when not in use to maintain sensor integrity.
