Ideal for those requiring an accurate alkaline reading, particularly suitable for those working in water purification plants, Hydroponics, and in any environments where the pH is expected to be alkaline. Hanna Microprocessor pH meters can be calibrated at pH9.18 and pH10.01.\u003c\/p\u003e \u003cp\u003eBuffer solutions should be stored at 25 C, away from direct sunlight for accurate readings.\u003c\/p\u003e \u003cp\u003eTo correctly maintain your meter\/electrode, we highly recommend use of a Hanna cleaning solution, as well as a buffer, for maximum performance every time. pH4, along with pH7, can also be used as an emergency storage solution.\u003c\/p\u003e \u003cp\u003eHanna buffer solutions are prepared, ready-to-use, according to precise formulas and standardised in accordance with the National Institute of Standards and Technology (NIST) to ensure quality and accuracy. All solutions show a batch number, an expiry date, and the correlation table between pH and temperature. A certificate of analysis is available on request. All bottled solutions are sealed with an air tight, tamper-proof seal to prevent any Carbon Dioxide from entering and causing a change in the pH buffer value.\u003c\/p\u003e \u003ch3\u003eBrowse the Hanna complete range of solutions\u003c\/h3\u003e \u003cul\u003e \u003cli\u003epH buffer solutions\u003c\/li\u003e \u003cli\u003eStandard solutions for conductivity, Total Dissolved Solids (TDS), turbidity, salinity and Ion-Selective Electrode (ISE) calibration\u003c\/li\u003e \u003cli\u003eOxidation Reduction Potential (ORP) test and pre-treatment solutions\u003c\/li\u003e \u003cli\u003eReference fill solutions for refillable electrodes\u003c\/li\u003e \u003cli\u003eGeneral and specific cleaning solutions for electrodes\u003c\/li\u003e \u003cli\u003eSolutions for electrode maintenance and storage\u003c\/li\u003e \u003cli\u003eSolutions for sample preparation\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eSolutions are available in many sizes ranging from 20ml sachets for small users to 3.78L (1 gallon) containers for large quantity usage in laboratories.\u003c\/p\u003e \u003cp\u003eFor safety and traceability, all Hanna solutions are provided with a label showing the batch number and expiry date.
