Laut Herstellerangaben kann das Messgerät PPFD messen. Bei mir funktionierte diese Funktion jedoch nur 10 Minuten. Nachdem ich das Gerät 10 Stunden später erneut nutzen wollte, zeigte es nur noch PRA-Werte an. Es gibt keine Möglichkeit, wieder auf PPFD umzuschalten, und wenn doch, scheint diese Funktion bereits defekt zu sein.Zudem scheint der Temperaturmesser nicht korrekt zu arbeiten. Ich habe zwei Thermometer als Referenz daneben gestellt, die beide 26 Grad zeigten, während das Gerät 29 Grad anzeigte, also einen Unterschied von 3 Grad. Sehr enttäuschend. Wer Qualität sucht, sollte meiner Meinung nach lieber zu einem anderen Produkt greifen.

Works well, waterproof, no issues. Only thing I didn't like was the extension pole, hollow and fills with water. But, I would buy again.

Die Messung für Vollspektrum Lampen sind wohl sehr genau. Temperatur und Relative Feuchte kann ich leider nicht bewerten. Bei dem Betrag sollte eine Tasche oder Koffer dabei sein. Es ist ein Messgerät und sollte auch deshalb pfleglich behandelt werden aber so hat man viele Kabel, Teile etc. die man schnell verliert oder suchen muss. Der Karton ist für mich keine Option da er viel zu dünn ist und bereits reißt. Des Weiteren wirkt es sehr billig verarbeitet. Sieht nach eigenem billigen Gameboy aus. Der Sensor an sich wirkt hochwertig.Die Software hat bei mir nicht funktioniert, hat ständig die Daten geladen und nicht aufgehört vor sich die Software aufgegangen.Lieber ein einfaches Gerät mit Koffer anstatt viel Zubehör das sehr billig wirkt.

I really do commend this company on procuring such a nifty product for a multitude of uses and not to mention waterproofing for those dealing with humid and wet environments. The app and remote both displayed accurate information and charting was a breeze. Responsiveness with measurements are fast and don’t require much tweaking and like I said you’re basically set with this little guy since no additional accessories are needed.

I have submerge this unit into a 40 gallon reef tank for dozens of time. It didn't leak like the other review said. The sensor is well built, the reader is easy to use, pretty much plug and play. It's a lot cheaper compare to other brand as well.

Fantastic device, my plants grow way better now that I know exactly where to move my lights. Don't know if it is as accurate or anything compared to the more expensive meters, but this has improved my grow. Wish I could find more of the humiture sensors it came with though. But awesome product in my opinion.

The VBR 200 is so much more than a PAR meter and is a must-have for growers and aquarium lovers alike.This device dose it all and at the price of your mid range PAR meter..It's also a master controller and can measure DLI, VPD, PAR and so much more at a fraction of the cost of other controllers..Set the desired ppfd and forget about it. The VBR 200 is the best device I have found lately and im very excited to introduce it to my clients in the coming months..I've been in contact with the seller both before and after the the purchase of his product of and let me tell you this guy knows how to stand behind his product!He answered every question I asked of him and was very helpful in helping me understand it's many uses.All that before the sell was made and I have been talking with him regularly ever since.Im excited about this product so much im going to use it in my light demo work and introduce it to my clients and followers..10 /10 will order again and would definitely buy again and recommend.Great gift idea if you know someone that deserves it.

My par sensor had shorted out and I need another one. The electrical unit itself works but the sensor that plugs into it has a split wiring case.

This meter is highly accurate compared to other name brand meters. The actual sensor itself is very durable and well made. The software is easy to load and works well to track dli. Having the color index option is a nice feature that you don't see on many other meters it really helps dial in light spectrum. Having the vpd sensor is a nice touch as well. Overall id recommend this to any grower wanting to measure PAR at a fraction of the cost of other meters.

Works great, simple instructions, doesnt need to connect to computer like some others. The Par levels seem very accurate, but I don't have a 2nd to back it up (the other review did show a comparison to Apogee which is why I bought it). Comes with the arm and things too, which the others dont...
