F-250 is an uv radiometer with great quality and high accuracy. Able to test the intensity, power, temp and the direction of highest value.

The instrument test probe is external, the measured spectral range can be divided into: UVA (320-390nm) @365nm; UVV (395-445nm) @405nm; UVV2 (445-500nm) @450nm. Customers need to choose the spectral range when purchasing. An instrument can only select one spectral range.

Long press power button to power on. Press the TEST button to enter the test state. The screen will display power and uv intensity data, switch page to view the power curve and temperature curve. Press the SELECT button to switch the display of the above different functions. Long press TEST button to turn off the power. Please refer to the use manual for details.

When the measurement is finished, press and hold the power button to turn off the instrument. 60s without induction or no button action, the device will automatically shut down. The correct operation will effectively extend the battery life of the instrument.
