Wireless Drop Counter (Local Stock)

Product Code: PS-3214-LS


The Wireless Drop Counter has a wider (18 x 13 mm) drop window for better drop detection and easier alignment with burettes. It works equally well with large or small, fast or slow drops.

Able to measure up to 40 events per second with drops as small as 0.5 mm.


  • Measures up to 10 drops per second
  • IR Filter assures accurate counts because room lighting cannot affect results
  • Sensor unit can suspend up to two other probes in solution, simplifying many experiments
  • Wider drop window (18 x 13 mm) means better drop detection and easier alignment with burettes
  • Splash resistant design to keep it safe from harm in wet labs
  • Automatically recalibrates for maximum sensitivity each time the unit is turned on.
  • LED drop indicator makes setup and testing easy
  • Long-lasting rechargeable battery (>200 hours on a single charge)
  • Included materials make it easy to set up a drop dispenser and easily control drop size and flow

Typical Applications

  • Titration
  • Investigating indicators
  • Chemical reactions
  • Counting drops and measuring volume

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.) It also includes a Drop Dispenser plus a stainless steel rod for easy attachment to a ring stand.
