Lab Meister: Measure & Manage

About

Lab Meister is the flexible one — for honey, industrial fluids, dairy QC, and general lab work. Whatever you measure, keep every reading and its range in one organized place. Connect your EasyDens density meter or SmartRef refractometer over Bluetooth and get precise results in seconds — or add readings by hand. No device yet? You can still log, organize, and export measurements, then connect one whenever you're ready. BUILT FOR MORE THAN ONE JOB - Honey & beekeeping — verify water content before bottling for shelf stability - Coolants & antifreeze — ethylene and propylene glycol concentration with automatic freezing-point calculation for reliable freeze protection - Cutting fluids, brines & syrups — check concentration up to 84 °Brix - Lab & water — hydroponics, wastewater, drinking water, dairy, glucose/fructose solutions SKIP THE MATH - Glycol concentration and freezing point computed automatically — EG or PG, in %v/v or %w/w, °C or °F - Automatic temperature compensation — values are already corrected, no tables needed - Pick your medium and Lab Meister shows the right units and range MEASUREMENT UNITS - Brix (°Bx), Density (g/cm³), Refractive Index (nD @20 °C), Water in Honey (%), Ethylene & Propylene Glycol (%v/v, %w/w), Glycol Freezing Point (°C, °F), and Temperature in °C or °F. A DATA HISTORY YOU OWN - Organize readings into custom logs with notes and timestamps - Keep per-reading notes and project notes for your methods and constants - Find anything instantly with full-text search - Export to PDF for clean reports or CSV for spreadsheets - Long-press any result to copy or share it ONE ACCOUNT, EVERY DEVICE A free Meister Cloud account syncs your logs across iPhone, iPad, Apple Watch, Apple Silicon Mac, Apple Vision Pro, and the web — one account for the whole Meister app family. Without an account, your data stays local on your device. For density and concentration you need an EasyDens; for refractive index, a SmartRef.
