Overview
The SMART SENSOR AS8125 Illumrination degree meter is an instrument for the measurement of light intensity (illuminance), that is, the measurement of the ratio of luminous flux to the illuminated area on the surface of an object. The instrument uses automatic gear selection, the measurement range can reach 1 to 200,000 Lux, and it has two measurement units: Lux and Fc.
Features
1. Wide measurement range, up to 1~ 200,000Lux.
2. Automatic gear selection, easy to operate.
3. Fast sampling rate, up to 2 times/second.
4. The instrument is lightweight and portable, with a net weight of only 80g and a size of 162 * 47 * 25mm.
5. Powered by 3 AAA batteries, convenient battery life.
Principle
Illumrination degree meters usually consist of a photosensitive element (such as selenium Photocells, photovoltaic cells or silicon Photocells, photovoltaic cells) and a microampere meter. Light shining on the photocell generates a photocurrent, which is proportional to the intensity of the light. The microampere meter displays the corresponding illuminance value by measuring this current.
Applications
Lighting engineering, architectural lighting design, indoor environment monitoring, agricultural lighting research, industrial production line lighting evaluation, photographic lighting
Standards
The data did not mention specific compliance criteria
Steps
Load three 1.5V AAA batteries.
2. Press the power button to turn on the instrument.
3. Align the instrument's Photosensitive Sensor with the Illuminant to be measured.
4. Keep the measurement position stable and read the illuminance value on the display screen.
5. After the measurement is completed, turn off the power.
Notice
• Do not use in environments beyond the operation temperature range (0~ 40 ° C).
• Make sure the surface of the Light Sensor is clean and unobstructed during measurement.
• Avoid exposing the Sensor to extremely strong rays of light for long periods of time to prevent damage.
• Regularly check the battery level to ensure measurement accuracy.
• The instrument accuracy is +/- 5% reading +/- 10, please pay attention to the error range.
• The instrument does not have waterproof function, please do not use it in humid or splashing environment.
