Data Harvest

Product Description


The Drop / Bubble Counter is perfect for highly accurate automated titrations. It can be used to count either drops of fluid falling from a dropping device e.g. during a titration, or bubbles rising through fluid in a column.

Bluetooth | USB | Huge Battery Life | Independent Logging 



Accurate Automated Titrations

The Counter makes use of an infrared beam which when interrupted (e.g. by a drop or bubble) creates a digital signal that is counted. The LED indicator will blink as a drop or bubble passes.

Use one of the 7 pre-calibrated ranges or count the drops and calibrate to the drop size. Accuracy is to the volume of the last counted drop.


Practical Teaching

The Counter can be used to investigate a number of scientific experiments such as:

  • Acid-base titrations
  • Large bubble counting for rate of reaction work
  • Gas Evolution
  • Fermentation monitoring
  • First derivative of rate of change of pH




Count Range 0 to ≈16x106
Volume Ranges 23 to 29 drops/cm³

Seriously Smart Wireless Bluetooth Sensors

Designed with new and existing customers in mind! 

A new Smart Wireless range of science sensors that also function as data loggers in their own right using Bluetooth or USB connectivity. The new Bluetooth wireless sensors include a huge battery life and can be mixed & matched with existing SmartQ Sensors & Data Loggers!

Works with SmartQ

Our wireless sensors can be used in combination with other Smart Wireless Sensors or data loggers in the EasySense range, even more amazingly is that with the addition of a V-Hub sensor link you can continue to enjoy using your existing SmartQ sensors at the same time!

The Power of Smart Wireless

Our Smart Wireless sensors build on the design of our legendary intelligent SmartQ Sensors but adds Bluetooth wireless connectivity allowing users to connect to tablets and mobile phones using the new EasySense2 Software. 

Digital Technology
Our digital sensor technology brings science to the classroom providing you with a robust, accurate and repeatable teaching experience from the start.


Auto Calibration
We have taken the hassle out of setting up your experiments with our pre-calibrated, auto identify sensor technology, every sensor is ready to use out of the box.


USB Charging
Our Smart Wireless sensors are powered by an internal battery and can be charged via a standard USB charger.


Designed for Mobile
With the included Bluetooth connectivity the new Smart Wireless Sensors can connect to Tablets, Mobile Phones, Laptops and Desktop Computers


Smart Connectivity

Not only do the Smart Wireless Sensors connect to multiple tablets and mobile devices via Bluetooth but they can also connect directly to a desktop computer and be used just like a traditional data logger whilst offering faster data transfer rates.
