Page 3: Introduction
Thank you for purchasing the Smart Wireless Conductivity Pack. We pride ourselves on producing high quality products that meet with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team. - Page 4 1112 - Wireless Conductivity Pack The range required is set in the Devices icon of the EasySense2 software Electrical conductivity is an inherent property of most materials. Electrons carry electric current in metal; in water electrical current is carried by charged ions. The conductivity of a solution is determined by the ability of a solution to conduct an electric current between two electrodes.

Page 6: Operational Overview
1112 - Wireless Conductivity Pack Operational Overview The diagram below shows the specific parts of the sensor. Read further to explore the functionality of each part of the sensor. The conductivity Electrode The conductivity electrode has two carbon plates of known size facing each other across a cell of a known width. - Page 7 1112 - Wireless Conductivity Pack Once you have selected OK the calibration will be stored as a user range. The calibration only holds for the electrode / sensor combination. If the sensors are separated from the electrodes, they will need re- calibrating.
- Page 8 Press and hold down the On/Off button for at least 8 seconds until the status LED gives a flash of blue light, then release. If the sensor fails to respond, contact Product Support at Data Harvest. Please provide details of: The computer platform it is being used with and the EasySense2 app’s version number.
