Bloomstar PAR Meter measures PPFD in the 400-700 nm range

We have been looking for a long time for a product that can compete with the well-known PPFD measuring devices - finally there is one! The Bloomstar PAR Meter measures PPFD (photosynthetic photon flux density) from 0-4000 µmol/m²s and also displays the corresponding DLI.

Why do you need a PPFD measuring device?

The measuring device for DLI and PPFD helps to recognise common errors such as hotspots, light stress or insufficient lighting and to take action. The number of photosynthetically active photons absorbed significantly determines the photosynthesis rate and therefore the yield in horticulture. If the lighting is set too high, high energy costs can be incurred. In this case, optimising the DLI saves money.

In plant lighting, the focus is increasingly on achieving homogeneous illumination. With the Bloomstar PAR meter, you can measure the PPFD to determine the optimum hanging height and dimming level of your light. The device is also extremely practical for troubleshooting, checking ageing lights / light sources and doubts about the manufacturer's specifications.

Features of the Bloomstar PAR Meter

With the spiral cable supplied, you can carry out PPFD measurements quickly and conveniently "by hand". A second, 5m long cable is included, for example to carry out stationary, longer-term measurements with the logging function (e.g. greenhouse). The sensor part has a 1/4″ thread for mounting on tripods and other devices.

You can always keep an eye on the measured values on the large LCD display. The PAR meter is powered by two AAA batteries (included).
