NexSens WQSensors offer direct computer interface via USB and are affordable water quality sampling toolkits suitable for a wide range of lab or field applications. They can connect to any Windows PC and several mobile devices using the six foot sensor cable with integral USB connector.
The WQSensor is powered from the USB port, and data is displayed in real time directly on the computer screen. When connected, the sensor’s unique ID is automatically recognized, and the most recent calibration, factory calibration, and probe status are displayed on the screen.
Sensor options include temperature, pH and temperature, ORP and temperature, dissolved oxygen and temperature, ammonium, bromide, calcium, chloride, fluoride, and nitrate.
Each of these smart USB sensors comes with WQSensors Software for interface and data collection. The program allows users to calibrate, log, and analyze data. Sample data refreshes every second, and readings can be set to log once or continuously at user-defined intervals. The software interface allows multiple sensors to be connected to a single computer, and the display automatically adjusts for viewing and logging multiple parameters simultaneously.
The program also features a one-click report generator for outputting summaries, statistics, graphs, and raw data points. Advanced options allow the user to adjust graph scaling, select time intervals, and more.
A built-in “Science Library” includes an interactive periodic table of elements, unit converter, aquatic species tolerances, and other useful information. These tools are especially helpful in the classroom setting to help students understand the meaning and relevance of collected water quality data.

For field measurements, NexSens WQMobile software offers a plug-and-play interface to the complete line of WQSensors. Simply plug the sensor into a Trimble Nomad or other field computer with USB interface and begin collecting data.
