Refractometers for maple sugaring

Sap and syrup refractometers are different instruments: sap (low-Brix, 0-10/0-18/0-32) vs syrup (must cover 66-69, e.g. 45-82); using the wrong one gives 'unintelligible readings'.

Our pick

Top pick: Small sugarhouse: Hanna HI96801 ($312) - the only unit read with a stated accuracy (+/-0.2%) and calibration method
Budget pick: Bascom 45-82 Brix syrup refractometer ($85) - correct maple scale; or skip refractometers entirely below 50 taps (hydrometer is the extension 'instrument of choice'); Scale range fit (45-82 covers 66-69 with room) and stated accuracy are the verifiable criteria; a hydrometer remains cheaper and extension-preferred for finishing.; What would change it: If Milwaukee publishes +/-0.2 at a lower street price it ties Hanna; optical ATC models with a stated 45-82 scale and ATC would beat the $85 unit.

What matters

How to judge refractometers

Each criterion names the extension or manual source it comes from; 'synthesis' marks our own reasoning.

2
Hand-held accuracy ~0.2 Brix; most are not for hot syrup (>180 F) - cool the sample; optical ones need good light; ATC (automatic temperature compensation) matters; calibrate with oil/glass (syrup) or distilled water (sap).

Digital models give higher-precision readings for value-added products; cost is the trade-off.
