Introduction

The PASCO Wireless Drop Counter is a versatile measuring
device that can connect to a computer or mobile device, either
wirelessly through Bluetooth or physically through a USB port. It
includes a rechargeable battery and a Micro USB Cable. It
measures the number of drops of fluid that fall through the
rectangular opening (drop window) of the sensor and converts
the drops into a volume. It is typically used in conjunction with a
pH sensor and other equipment to perform a titration. Data from
the Wireless Drop Counter and other sensors are recorded and
displayed using software such as SPARKvue or PASCO
Capstone. SPARKvue allows the sensor to work with a computer
or a mobile device such as a tablet or smartphone when the
sensor is connected. PASCO Capstone will work on a PC or
Mac.

The Wireless Drop Counter can be mounted on a support rod.
The counter is equipped with two integrated probe holders. The
included Micro Stir Bar fits onto the end of a pH probe or other
probe of the same diameter.

The included syringe, syringe holder, stopcock valves, and drop
tip can be assembled into a drop dispenser that can be mounted
on a support rod.
