Tint Meter,visible transmit light rate(400-700nm),rejection rate of UVA(365-400nm) and Solar Power(>1000nm).Display test results for 5 kinds of car windows.

I mainly used for detecting UV and IR lighting in my greenhouse (edible herbs) as I'm supplying these spectrum to hopefully get better aromas and taste from Basil and other edible herbs. On tomatoes I noticed an increased production and frequency of flowers growth development when using UV and IR. The app V-Sensor can be used to take measurements in three different spectrum range, including visible light. Bear in mind this doesn't read PPFD but you can make some approximate conversions.

Doesn't work so sending it back advice to people reading this is don't bother buying

A useful piece of equipment to measure the performance of glass. This is marketed for tint installers where there are legal requirements. For example, in the UK front windows in vehicles must let at least 70% of light through. The sensor also measures the UV and IR wavelengths to indicate the heat rejection and skin protection provided. You need to download the Vsensor app from the Apple or Google Play stores to access the data. The sensor connects easily via Bluetooth providing W/m² for red, green and blue in the visible spectrum as well as UV and IR. The app also does the calculations for you so you can take a reading with a clear view and a second through the glass you are testing and it will calculate the percentage of light transmitted at different wavelengths. There is no information provided about calibrations, but if you are only interested in percentage difference that is not so critical. I have learnt that in my conservatory 82% of UV light is blocked compared with sitting in the garden in direct sun. At £53, I don't think this is too expensive for a piece of professional test equipment. Even if a professional installer has more complicated test equipment they may be interested in this to perform a quick check as it is so easy to use.

The build quality is top-notch, giving a sturdy and durable feel right out of the box It even comes with an extra battery, which is a nice touch The sensor for visible light, UVA, and IR, sourced from a Japanese company I'm not entirely sure what the practical uses of this are but seems like a nice gadget

Documentation could be a tiny bit better... I got the device connected pretty quickly (You even have an extra battery), but it doesn't show the best way to take the measurement. Should the car be facing the sun, does it have to be a sunny day... I would have like a little bit more details. Data scanning is SUPER quick ! The app is really basic but will visualized the informations. I just wish it had some storage method for the data. But instead, I take screenshot and write on it so I know which location I tested. There is not much to this unit. It seem to contain not much inside, as it super light, but they did put a nice slip free pad behind, but it could be less good and it wouldn't change anything, but it the only thing that feel good, so I'll take it. It will be interesting to see what this read during a solar eclipse though different type of glass !

Sono molto soddisfatto di questo prodotto. La costruzione è solida e resistente, dando un'impressione di qualità fin da subito. La presenza di una batteria extra è molto apprezzata. Il sensore per la luce visibile, UVA e IR, proveniente da un'azienda giapponese, si è rivelato molto preciso durante i test. Ho trovato particolarmente utile la capacità di mostrare direttamente il potere di radianza di UV, R, G, B e IR sia all'interno che all'esterno delle finestre. Questo mi ha permesso di valutare l'efficacia dei vetri oscuranti e delle pellicole protettive che ho installato a casa mia. La funzione di test della radianza solare è molto convincente offrendo una misurazione più realistica delle condizioni di luce naturale. Ho utilizzato questo prodotto per verificare l'efficacia delle lenti polarizzate e degli occhiali da sole, scoprendo che alcuni non offrivano la protezione UV dichiarata. L'app collegata è semplice da usare e la connessione Bluetooth è stabile e affidabile utile durante le escursioni all'aperto, dove non sempre ho accesso a una rete. Consiglio vivamente questo prodotto a chi cerca precisione e versatilità in un misuratore di colore, sia per uso professionale che per semplici verifiche domestiche.

I use this to check the vehicle tint installed already for penetration of visible light-ultra violet-infra red. It is easy to use and can record the results from all windows front/rear/side/sunroof. The build quality is good and handy. Value for money. It is accurate for practical daily use. Now i can find out if the tint is too dark for night driving. I will know when to open or shut the sunroof too to protect my skin against sunlight.

Das Farbtonmessgerät an sich ist technisch vollkommen in Ordnung. Leider erhält man nur eine veraltete App, die seit Jahren nicht aktualisiert wurde und die absolut keine erweiterten Funktionen bietet. Angezeigt wird ein W/m² Wert, mit dem man zum Beispiel die Effektivität von Sonnenschutzfolien und Sonnenbrillen testen kann. Ich verwende das Gerät auch, um die Lichtintensität von Pflanzenlampen zu messen. Die Messwerte kann man leider nicht speichern, was die Arbeit mit dem Gerät mühsamer macht, als es sein sollte. Wieso man die App für so ein Gerät nicht weiterentwickelt, damit der Funktionsumfang erweitert wird, ist fraglich. .Das Gerät ist zwar verwendbar, aber sollte man in dieser Preisklasse alternative Geräte finden, dann würde ich definitiv dazu raten, diese vor einem Kauf zu vergleichen.

まず、これが何なのか説明します。 車のスモークガラス等の透過率を測定するセンサーです。 １ステップ目で窓の外で環境光を測定します。２ステップ目で窓の内側から測定し、バックグラウンドからどれだけ透過したのかをRGB・赤外線・紫外線の各成分ごとに表示します。商品説明ビデオを見れば測定イメージがつかめると思います。 放射照度（W/m^2）の値の妥当性は分かりませんが、比率は正しいと思われます。ただし、紫外線だけは精度が荒いようです。室内のLED照明ぐらいではギリギリに近づけても反応しません。太陽光で測定するといきなり0.53W/m^2に跳ね上がります。何度測定しても0.53W/m^2と1.06W/m^2しか表示されないので、測定単位が0.53W/m^2となっているのではないかと思います。赤外線に関してはよく反応します。 あと、英語のレビューにも書かれているのですが感度カーブに関する情報が一切ないです。例えば青はどこからどこまでの波長を拾っているでしょう？３８０nmはブルーライトとされていますが、紫外線の波長（10 - 400 nm）と被っています。どちら側に判定されるんでしょう？
