Product Summary
At last, a professional Drop Counter can become part of your student lab. Our Drop Counter has a wider (18 x 13 mm) drop window for better drop detection and easier alignment with burettes. Works equally well with large or small, fast or slow drops. Easy calibration requires entering just one number into the computer. Includes a Micro Stir Bar for use with our pH and Conductivity Probes.
- Measures up to 40 drops per second with drops as small as 0.64 mm.
- Silicone rubber-sealed polypropylene is fluid-resistant and protects sensor from mild acids and bases.
- Automatically recalibrates for maximum sensitivity each time the unit is turned on.
Features
- Holds up to three sensors in a 150 mL beaker
- LED drop indicator

Product Guides & Articles
pH Sensors & Probes
A pH sensor is a type of probe used to measure the pH of solutions in chemistry, biology, and other science applications. pH probes are often used to determine the basicity or acidity of an aqueous solution.
Titration
A titration is a chemical analysis in which a researcher determines the concentration of a chemical solution (analyte or titrand) by adding a measured volume of standard solution (titrant) until the produced reaction reaches the equivalence point.
