2- Brief and Concise Product Description
The FNIRSI FPM-02 is a professional and modern digital lux meter (light meter) that replaces old analog testers. This device combines high accuracy and ease of use, enabling measurement of light intensity in two units: LUX and FC (foot-candle).
Unlike traditional models that consume a lot of battery power, the FPM-02 is equipped with an internal rechargeable battery. Its ergonomic design, 2-inch color display, and sensor with optical filter make this tool an ideal choice for lighting engineers, photographers, and modern agricultural professionals. Calibrated accuracy based on standard incandescent lamps provides high reliability for sensitive projects.

4- Full Product Introduction Section
The FNIRSI FPM-02 goes beyond a simple light meter; it is a lighting analysis tool designed to optimize energy consumption and improve ambient light quality.
Price and Purchase of FNIRSI FPM-02 Lux Meter
If you are looking to buy a durable and accurate lux meter that does not require frequent battery replacement, the FPM-02 is the best option on the market. Considering its color display and silicon sensor, this device is very competitively priced and economically suitable for engineering projects and HSE inspections.
Sensor Technology and Cosine Correction
One of the challenges in measuring light is the angle of incidence. The FPM-02 minimizes measurement errors at side angles by utilizing cosine angle correction. This feature, along with the internal optical filter, ensures unwanted light spectra are filtered out, and only the actual ambient light intensity is read.
Advantages and Practical Limitations
Advantages: Long battery life, high readability color display, lightweight, and professionally calibrated accuracy.
Limitations: This device is optimized for indoor environments and is not recommended for use at altitudes above 2000 meters or in very high humidity environments.
5- Target Customers
Greenhouse Growers and Plant Cultivators: For precise adjustment of supplemental light to optimize plant growth.
Occupational Health Engineers (HSE): To measure standard lighting in workplaces and factories.
Photographers and Videographers: For scene lighting adjustment and achieving accurate exposure.
Interior Designers and Architectural Lighting Specialists: To ensure uniform light distribution in residential and office spaces.
Energy Inspectors: To evaluate lighting system efficiency and reduce electricity costs.
6- Frequently Asked Questions (FAQ)
What is the difference between LUX and FC units in this device?
Lux (LUX) is the metric unit and foot-candle (FC) is the imperial unit for measuring light intensity. The FPM-02 allows quick switching between these two units.
Is this lux meter accurate for LED lamps as well?
Yes, the silicon sensor is calibrated for visible light sources. However, its highest accuracy (±3%) is for standard light sources, and for others like LEDs, accuracy is within ±6%, which is still considered professional.
How long does the device battery last?
With a 1500mAh capacity and efficient display consumption, the device can be used continuously for hours on a full charge and can be charged with a mobile Type-C cable.
Does the device support calibration?
This product is factory calibrated by FNIRSI according to optical standards (2854 Kelvin incandescent lamp) and is ready for use.
