Hire our most advanced PAR meter — designed for maximum accuracy, deeper readings, and enhanced spectrum analysis.
The PRO version measures not just how much light is in your tank, but how much of that light your corals can actually use (cPUR). This gives you a far clearer picture of whether your lighting is truly effective, not just bright. It also offers a wider spectral range including near-UV, improved accuracy in lower light, and full DLI and spectrum-analysis tools. These improvements make the PRO easier to use and far more informative, helping you dial in your lighting with confidence.
5-day hire: £45 hire fee + £105 refundable deposit
10-day hire: £65 hire fee + £85 refundable deposit
Your deposit is refunded once the meter is safely returned and checked.
After checkout we will email you to arrange a delivery date.
Return the meter via post — we recommend Royal Mail Tracked 24 for a fast, reliable return.
Attach our address label and pay the return postage.
If you do not have a compatible Android device or PC, you can hire a compatible device for an additional £10.
All PRO meters are currently out on hire.
New orders will be fulfilled when a meter becomes available — estimated 19/12/2025.
