Handheld Spectrometer for Light Measurement,340-1000nm Portable Spectrum Illumination Meter,Real-Time CCT CRI PAR PPFD Analysis,LED Grow Light Tester with APP & PC Software,USB Type-C Connection

Received and so far this is seems quite good, esp. for the price point. Not high precision but it has a wide measurement range, ok sensitivity, and seems to be reasonably accurate when measuring known spectra.

Unfortunately it only shows a cri R8 reading which is pretty useless. Would be really nice to see R9

Updating. There was a port issue with my computer. I was able to get it to work with a windows pc. Overall, solid spectrometer. Recommend for initial readings for testing.

This is a descent meter for the money. It has a nice range, better than some models 3x the price, fairly easy to hook up to Android with an app. App is fine. Docs online were in Chinese (translated OK). I compared the data it generates with another reader, which is 3x the price, and the data is very similar. If I had to nit pick: 1. Seems to require a fair amount of light (>100lx?) to read. 2. Flicker analyzer would be nice, like some other models have 3. Reading can take a few seconds, even in good light
