ORP Calibration Buffer Powder — 256 mV Redox Potential Analyzer / Test Pen Calibration Buffer Key benefits Portable, lowcost alternative to premixed ORP liquids: powder form eliminates heavy, fragile liquid shipments and reduces transport costs. Easy onsite preparation: one pack becomes a readytouse 256 mV ORP calibration solution with a single simple step. Reliable calibration for accurate measurements: formulated to produce a stable 256 mV reference solution for ORP meters and redox test pens. What it is and how it solves problems A newly developed ORP correction buffer in powder form designed for convenience and safe transport. Ideal where liquid buffers is inconvenient or expensive. Converts to a standard 256 mV calibration liquid by adding a controlled volume of distilled or purified water, enabling fast, repeatable calibration anywhere. Preparation (simple) Add 50 ml of distilled water or purified water to one pack of powder. Stir or shake until fully dissolved. The resulting solution is a 256 mV ORP calibration buffer ready for use. Compatibility and performance Function: Produces a 256 mV redox (ORP) calibration solution for calibrating ORP meters and redox potential test pens. Compatibility: Suitable for ORP/Redox analyzers, handheld ORP meters, and test pen style ORP instruments that require a 256 mV calibration point. Material: Dry powder formulation for ondemand buffer preparation. Performance: Provides a reproducible 256 mV reference when prepared as instructed, supporting accurate ORP measurement and instrument calibration. Practical applications / use scenarios Field calibration for water quality monitoring: carry lightweight packs to remote sites and prepare calibration solution onsite for ORP probes used in rivers, reservoirs, or environmental surveys. Pool and spa maintenance: quickly prepare a calibration standard to verify handheld ORP testers used for oxidation potential and sanitizer monitoring. Lab or workshop calibration: keep powder packs as compact backups to prepare fresh 256 mV buffer for routine instrument checks and educational labs. Additional notes Use distilled or purified water only to ensure correct ionic strength and accurate 256 mV value. One pack plus 50 ml water yields a single 256 mV calibration solution. Follow instrument manufacturer recommendations for calibration procedure.
