PASCO PS-4210 Quick Start Manual

WirelessConductivitySensor with OLED Display
Introduction
The Wireless Conductivity Sensor with OLED Display measures
conductivity over a range from 0 to 40,000 microsiemens per centimeter
(µS/cm). The probe is able to work in a variety of solutions. The
measurement is displayed at all times on the OLED display on the front
of the sensor. You can also transmit the measurements (either wirelessly
via Bluetooth or using the provided USB-C cable) to a connected tablet
or computer, where they can be displayed and analyzed using PASCO
Capstone, SPARKvue, or chemvue data collection software. Since each
sensor has a unique device ID number, more than one sensor can be
connected to a computer or tablet at the same time.
The Wireless Conductivity Sensor with OLED Display is powered by
a rechargeable battery and is well-suited for both continuous recording
and discrete measurements. The sensor is designed to optimize usage of
the battery between recharging.
CAUTION: Do NOT immerse the sensor body in water or
any other liquid! The housing is not waterproof, and exposing
these components to liquid may result in electric shock or
permanent damage to the sensor. Only 1-2 inches at the end of
the probe need to be immersed in the liquid to obtain accurate
conductivity measurements.

Capstone or SPARKvue online help. (This feature is not available
in chemvue.)
USB-C port

Charge the sensor by connecting this port to a standard USB
charger via the included USB-C cable. You can also use this
cable and port to connect the sensor to PASCO Capstone,
SPARKvue, or chemvue without using Bluetooth.

Press to turn the sensor on. Briefly press and release twice in
quick succession to toggle between different measurements on
the OLED screen. Press and hold to turn the sensor off.
Background
Electrolytic conductivity is defined as the ability of a liquid to conduct
electrical current. In conductive solvents, dissolved ions are the main
conductors of electricity. By selecting the appropriate electrode, one can
easily measure the electrical conductivity of liquids ranging from ultra-
pure water to extremely salty solutions. How well a solution conducts
electricity depends on the concentration, mobility, and valence of its
ions, as well as the solution's temperature.
The Wireless Conductivity Sensor determines the electrical conductivity
(EC) of a solution by measuring the alternating current (AC) flowing
through a circuit when the AC signal is applied to a 2-cell electrode
submerged in the solution.
