Apogee mq-510 vs. ITC Parwise issue?

[cubalibre79]

Need help again,

try to handle 4 radion xr30 pro over my 132gallon tank.

my problem, wich par meter should i trust?

my apogee mq-510 with blue sensor read 360 par ~ 16“ under the light. Parwise reads a lot lower and try to tell me 360 par @ 100% intensity

maybe someone can compare to my screenshot.

Yup, maybe time to sell mine.
Still kinda useful but wish they just did an upgrade.

What exact par are you SPS users looking for.

There is no exact par, it's what your coral need.
I personally have about 350/400 at the top coral in my tank.

The apogee 510 is on sale for 399 and parwise is at 299.

Telegraham did a comparison between them and the ParWise needed to be multiplied by 1.17
Now they have a new one coming out could make it be completely different.

Your probably better off buying the apogee, everyone considers that the standard in this hobby anyway.
There is a version you can plug into your computer and it's just the head. It's cheaper than the full model of you have a computer close by.

another question.. does the parwise store on a spread sheet readings ect.. In other words is there an app or something ?

Nope.
I plug into a small laptop, phone or screen and do screen shots. The software is on there end and you connect to it thru the app.
I think you can do dli but I have not. That's the whole light sequence from sun up/sundown and quite frankly, not sure how it spits a number out or how to use it.

Negative. 1.17X was for the new sensor-equipped VBR PAR meter. This one - https://a.co/d/8eFHeXT When I first tested the PARwise, it required a ~1.31X multiplier to align with Apogee or the much closer to Apogee readings $130 VBR.

Thank you for correcting me.
I must have mis-read that number.

Thank you for the updates.. I did go ahead and spend an hour or so watching the parwise videos. Was informative on overall light par lux ect. They acknowledged some things in the video of why the Parwise results in a lower par reading. Not sure if I am translating - communicating this correctly so take it with a grain of salt.. The Parwise reads differently and does not include UV below 400 as part of the par. The Parwise takes the input and plots it to show the peaks and range, but for par numbers it does not factor below 400 into the par calculation.

That's marketing. Here's the info on the Apogee. Their marketing suggests that ITC's marketing is something other than accurate.

I recommend the VBR because the reading aligns with the $600 500-series Apogee, and it does it for <$150. Regarless of why, the PARwise reads low.

This was the original share when the opaque VBR sensor was released. When the sensor was more clear, the readings were aligned with the 500-series Apogees.
