PS2117_MAIN.jpg

Overview

At last, a professional quality Drop Counter can become part of your student lab. Our Drop Counter has a wider drop window (18 x 13mm) 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.

  • Measures up to 40 drops per second with drops as small as 0.64 mm.
  • Silicone rubber-sealed polypropylene enclosure is fluid-resistant and protects sensor from mild acids and bases.
  • Automatically recalibrates for maximum sensitivity each time the unit is turned on.
  • Holds up to three probes in a 150 mL beaker
  • LED drop indicator
  • IR filter rejects all visible light - not susceptible to variations in room lighting

Now includes a Micro Stir Bar for even better titration data. The Micro Stir Bar connects to the end of your pH or Conductivity probe and maintains a constant constant flow of solution over the end of the electrode. Works with a standard stir plate. (Additional Micro Stir Bars are also available separately.)
