You can use the OS1301 meter to measure the light levels when installing new lamps or lighting, ensuring the correct overall luminance has been achieved. By measuring the light intensity thereafter on a regular basis (monthly or quarterly) you can ensure optimum performance, and replace lamps as necessary.

The pocket sized OS1301 measures both Lux or foot-candles over the range of 0 to 50,000 lux/foot candles in four ranges, with a resolution of 0.1Lux/Fc.

Horticultural & hydroponics
The correct level of light is a necessity for plant growth. Sufficient light is needed for photosynthesis to take place so plants can flower or bare fruit. Commercially, it is important to regularly check artificial lighting levels to ensure healthy plant growth. The lack of adequate light is the most common cause for poor plant growth. As artificial lighting will degrade in intensity with time, it is essential to measure at regular intervals.
