Measure what your plants actually receive

A powerful grow light does not automatically provide the correct amount of usable light at plant level. With this PAR Light Meter, you accurately measure how much Photosynthetically Active Radiation (PAR) your plants actually receive. The light intensity is displayed as PPFD (Photosynthetic Photon Flux Density) in μmol/m²/s, the international standard for evaluating grow lighting.

By measuring at different locations under the lamp, you can easily determine the optimal hanging height, light distribution and light intensity. This way, you utilize the available light optimally and prevent both light deficiency and overexposure.

Suitable for every type of grow lighting

The PAR Light Meter measures the full PAR spectrum from 400 to 700 nm and is suitable for almost every type of grow lighting. Whether you work with modern LED grow lights, CMH lighting, HPS lamps or plasma lighting, you always get a reliable measurement of the amount of usable light that reaches your plants.

This makes the meter ideal not only for comparing different light sources, but also for optimally adjusting existing grow setups.

Professional measurement, easy to use

The PAR Light Meter features a large LCD display, a practical HOLD function and a data logging function that can store up to 100 readings. The separate sensor is equipped with a ¼ inch tripod connection, so measurements are easily reproducible.

Thanks to the included coiled cable and data cable, you have sufficient freedom of movement to measure at different locations in the grow tent or grow room.

Get the most out of your grow lighting

By regularly checking the PPFD and PAR values, you can accurately assess and optimize the performance of your grow lighting. This allows plants to grow more uniformly, you utilize the available light energy more efficiently and you create optimal conditions for every growth phase.
