Overview
The SMART SENSOR AS813 luminometer is a professional measurement of light intensity (illuminance) to quantify the degree to which an object is illuminated, that is, the ratio of the luminous flux obtained on the surface of the object to the illuminated area. The instrument is composed of selenium Photocell, photovoltaic cell or silicon Photocell, photovoltaic cell and microampere meter. It has automatic gear selection, LCD screen and overload prompt function. Measurement range covers 1 to 200,000 Lux, suitable for a variety of lighting environment monitoring.
Features
1. Measurement range is wide, covering 1~ 200,000 Lux, to meet different light intensity requirements.
2. Automatic gear selection, easy to operate, no need for manual adjustment.
3. High Accuracy measurement, Illuminance accuracy of +/- 5% reading +/- 10, Repeatability +/- 2%.
4. Fast Response, Sampling rate 2 times/second, Response Time is only 1 second.
5. Lightweight design, Dimension 220 * 65 * 30mm, weight only 192g, easy to carry.
6. The LCD screen clearly displays data and supports Lux and Fc Unit switching.
7. Built-in overload prompt function to protect the instrument from damage.
8. Using 9V battery power supply, stable battery life, Operating temperature range -10~ 50 ℃.
Principle
The luminometer senses the light intensity through selenium Photocells, photovoltaic cells or silicon Photocells, photovoltaic cells, converts the light energy into an electrical signal, and then measures and displays the illuminance value by the microammeter. Its core principle is based on the ratio of the luminous flux to the irradiated area of the object surface, and automatically calculates and outputs the illuminance data in units of Lux or Fc.
Applications
Industrial lighting inspection, building lighting assessment, agricultural lighting monitoring, laboratory Light intensity measurement, environment monitoring, education and research
Steps
1. Turn on the power supply of the instrument to ensure that the battery is fully charged.
2. Align the luminometer Sensor with the Illuminant to be measured and keep it stable.
3. The instrument automatically selects the appropriate gear and starts the measurement.
4. Read the illuminance value on the LCD screen (in units of Lux or Fc).
5. Turn off the power after the measurement is completed to save power.
Notice
• Avoid use in extreme temperature environments (below -10 ° C or above 50 ° C) to prevent affecting accuracy.
• Make sure the Sensor surface is clean and unobstructed during measurement.
• When the display screen shows an overload prompt, immediately stop the measurement to avoid damage to the instrument.
• Regularly check the battery level, low battery level may cause measurement errors.
Store in a drying place to protect against moisture or mechanical Impact.
