Accuracy
When the light is sunlight, LED, HPS, CMH, it can provide accurate data.
PPFD Testing Range
Mostly measured to 2000 at present.
Wavelength Testing Range
380-780nm is preferred.
Spectrum
Can be test. Preferably in the form of SQD.
Response Time
Preferably set up. It can be displayed instantaneously. You can also set the corresponding delay time. For example, when measuring the PAR value in the tent, you need to close the tent to get the most accurate data, which requires enough time for the zipper of the tent.
Price
The current market price ranges from US$20 to US$1,500.
Convenience
There is a telescopic rod to measure the PPFD at a longer distance. There are several sensors on the telescopic rod, which can measure the data of several points at the same time, saving time.
Record Function
Can store the tested data.
APP Control
Can be connected to mobile phone via WIFI, which is convenient for remote monitoring. Test instruments located in multiple locations can simultaneously display the corresponding PAR values on the same interface.
Hold
Convenient
Duration of Use
Because the battery is used.
