Did you know that you really can’t calibrate a Vernier Drop Counter? Instead, you are actually calibrating the tip of the titrant reservoir. The Vernier Drop Counter is a modified photogate designed, through the software, to monitor drops of ...

An Oxidation Reduction Potential (ORP) Sensor measures the activity of oxidizers and reducers in an aqueous solution. It is a potentiometric measurement from a two-electrode system similar to a pH sensor. Sometimes it is also referred to as a ...

Tip #1: Keep Your pH Sensor Hydrated Storing your pH Sensor in storage solution is important for preventing the reference electrolyte from leaching out, keeping the junction clear, and keeping the glass tip hydrated. If you're out of pH storage so...

A calibration equation is stored on each pH Sensor before it is shipped. For the most accurate measurements with this sensor, we recommend you perform your own 2-point calibration with buffer solutions. As the pH Sensor ages, the performance of the ...

pH is a quantitative unit of measure that describes the degree of acidity or alkalinity of a substance. It is measured on a scale of 0 to 14. The formal definition of pH is the negative logarithm of the hydrogen ion concentration (i.e., pH = –log...
