Description
Product Overview
The GIDIGI Redox Buffer 222mV pH7.00 solution is engineered to deliver high‑precision oxidation‑reduction potential (ORP) calibration for a wide range of laboratory and industrial instruments. Each kit contains two 250 mL bottles of the 222 mV redox buffer, a 30 mL bottle of ORP electrode storage solution, and two durable beakers for measuring and mixing. The formulation is based on a stable, well‑characterized redox couple that maintains its potential within ±0.05 pH units at 25 °C (77 °F), providing reliable reference points for routine calibration. The buffer is compatible with all major ORP meter brands and models, as well as pH meters calibrated at the neutral pH 7.00 point, making it a versatile tool for quality control laboratories, research facilities, and process monitoring stations. The product is packaged in a compact, resealable container measuring 7.4 × 5.94 × 2.6 inches and weighing 1.13 lb, ensuring easy storage and transport. Manufactured by JiNan Huiquan Electronic Co.,Ltd, the solution meets stringent industrial standards and carries an Amazon Best Sellers Rank of #27 in Electrolyte Solutions, reflecting its popularity among professionals who demand accuracy and consistency.

Usage
Designed for both laboratory and field applications, this redox buffer kit supports a variety of usage scenarios. In a typical laboratory setting, technicians dip the ORP electrode into the 250 mL buffer solution to verify the meter’s response, then rinse and store the electrode in the 30 mL storage solution to preserve its sensitivity between measurements. The buffer is also ideal for calibrating pH meters at the neutral point, ensuring that pH readings remain accurate across the full measurement range. In industrial environments, the solution can be used to calibrate process control meters that monitor oxidation‑reduction reactions in water treatment, food processing, and chemical manufacturing. The long‑lasting supply of 250 mL per bottle provides enough volume for hundreds of calibrations, reducing the need for frequent re‑ordering and minimizing downtime. Users should store the kit at room temperature, away from direct sunlight, to maintain solution stability. The included beakers facilitate precise measurement of small volumes, allowing users to prepare diluted solutions or perform side‑by‑side comparisons with other standards. Whether you are conducting routine maintenance, performing method validation, or troubleshooting sensor drift, the GIDIGI Redox Buffer kit offers a reliable, ready‑to‑use solution that integrates seamlessly into existing workflows.

FAQ
What is the recommended storage condition for the redox buffer?
The buffer should be stored at room temperature, away from direct sunlight and extreme temperature fluctuations, to maintain its electrochemical stability.
Can this buffer be used for calibrating both ORP and pH meters?
Yes, the 222 mV redox buffer is suitable for ORP calibration, and the pH7.00 component provides a reliable reference point for pH meter calibration.
How many calibrations can I expect from one 250 mL bottle?
Depending on the volume used per calibration, a single 250 mL bottle can support several hundred calibrations, making it a cost‑effective solution for high‑throughput laboratories.
Is the electrode storage solution compatible with all electrode types?
The 30 mL storage solution is formulated to be compatible with most standard ORP electrodes, helping to preserve electrode performance between measurements.
What should I do if I notice a drift in my ORP readings after calibration?
First, ensure the electrode is properly rinsed and stored in the provided storage solution. If drift persists, check for contamination, replace the electrode if necessary, and verify the calibration using a fresh buffer solution.
