Frequently asked questions

Do AquaHorti meters require an app?
It depends on the model. AH‑Reef and AH‑SOL can be used without an app. AH‑PARDLI uses the AquaHorti app over Bluetooth to view live PAR, light curves, DLI history and export CSV data.
Does AH‑PARDLI need internet access while measuring?
No internet connection is required for measurement after the app is installed. AH‑PARDLI communicates with the AquaHorti app by Bluetooth.
Which meter is best for grow lights?
Use AH‑Quantuv for spot PAR/ePAR, UVA and R/G/B comparison. Use AH‑PARDLI when you need day-long PAR logging and DLI history. Use AH‑200 when PAR must be evaluated together with CO₂, temperature, humidity and VPD.
Are AquaHorti probes waterproof?
AH‑Reef includes an IP‑rated waterproof probe designed for aquarium submersion. Other models use probes designed for their stated environments; check each product page before submersion.
Are the meters calibrated?
Measurement models are factory calibrated and verified according to their specifications. See the individual product page or contact AquaHorti for model-specific documentation.
