Reliability PAR-Meter VBR-Aqua Vabira

[tom33]

Hello everybody,
I have just purchased the VBR-Aqua Vabira par-meter, and I have questions about its reliability
I get 500 from Par, the sensor in the middle of the aquarium and at water level
Test carried out with a hydra 32 HD purchased in 2020 at 30cm from the water level
The results seem consistent to you?
If anyone is interested I plan to do the same test with a new radion x15 g5 blue

Sorry for my broken english

read through this thread: https://www.reef2reef.com/threads/vbr-aqua-par-meter-for-aquarium-r-g-b-par-seperately.1011898/

see if that helps point you in the right direction , and i also have a hydra32hd(two, actually!) over a 40B.

i use this PAR meter. all i do is multiply by 1.17 and i have a near/same reading to an apogee500 meter.

Thank you for the link

I have the newer VBR Aqua with the lens that are not as see through as the older model. I just purchased the apogee mq-510. Tested them both over my waterbox 50.3 running 2 ai prime hd’s. Found that the apogee reads higher par than the VBR. I tested 3 areas In the tank for comparison with return pump and wave makers off. Apogee tested 145, 100, 150
While in the same three spots the VBR tested 96, 50, 100.

Thanks a lot for your reply
you what probe on the VBR ?

I have the same probe as the bottom one circled in pic. From what I understand it’s the newer sensor that is not as see through as the older one.

 

[tom33]

Ok I have the top probe
I hope I don't have that many differences
thank you for sharing your experience

mine has been fine. I have the more opaque sensor so have been multiplying by 1.17. It certainly more accurate than my seneye which reads about 2.5% higher than the VBR (and outside the realm of possibility given what my lights are set to).

 

[tom33]

I will definitely rent a quality setting to compare with mine

the multiplier recommended by @telegraham was to have it be around the results of the apogee500, i believe. the results will be much more different when comparing the apogee510 to the VBR aqua.

nonetheless, for roughly 200$ i’d rather have this than either of the apogee, or the seneye. i can use the extra 300$+ for more critters or tank supplies

 

[tom33]

I agree with you
I'm not close to 50 PAR
I will add 50 PAR more for safety, i might have the opportunity one day to rent one or compare it with another better quality par-meter
Thank you again for your feedback

That's incorrect. The VBR multiplier is only for the new VBR sensor. The old VBR sensor does not need a multiplier to align with 510 readings.

When I share numbers, they're captured on a 500 and immersion corrected to 510 values.

thanks for clarifying!
