A mechanical refractometer's calibration drifts, its readings depend on your eye lining up a shadow correctly, and it takes zero temperature into account - an electronic conductivity-based tester removes all three problems. The IceCap SPT03 gives you both salinity and temperature in one reading.
Why Electronic Beats Mechanical
A refractometer requires manual calibration, correct lighting, and a steady hand reading a shadow line - real sources of user error that an electronic conductivity probe simply doesn't have. It also reports temperature simultaneously, something a refractometer can't do at all.
What It Offers
- Electronic conductivity-based reading for salinity, removing the shadow-line reading error a refractometer introduces.
- Simultaneous temperature reading, giving you both numbers from a single dip.
- Pocket-sized design that's easy to keep on hand for quick checks.
Setup Tips
- Calibrate periodically using a known reference solution to maintain accuracy over time.
- Rinse the probe between uses, especially between testing different tanks.
- Keep batteries fresh, since a weak battery can affect electronic reading accuracy.
