Record 400 points of PAR, convenient to record the PAR of each position in the tank. DLI for 28 days.
3 AAA batteries can ensure the PAR meter last for 100 hours. Also can use the adapter for continuous testing.
For stable and accurate PAR, please don't let water flow when test.
Accurate PAR Readings No Immersion Correction Applied
The PAR meter is calibrated similarly to a famous brand and provides direct sensor readings of PAR (µmol/m²/s).
Unlike the XX-510, VBR-Aqua does not apply an Immersion Effect Correction Factor (IECF).
As a result, underwater PAR values appear about 25% lower higher than those from an XX-510 this is expected and does not mean the readings are inaccurate.
PAR Recommending for Different Corals
VBR-Aqua can test PAR and Daily Light Integral (DLI).
For new VBR-Aqua that arrived warehouse in April 2025, the UV testing function has been added. Telescopic rod has been changed to a screw-together rod
