                                                     NexSens WQSensors
NexSens WQSensors are the latest in smart sensor technology with direct computer interface. An integral USB
connector offers a simple, hassle-free connection without meters, batteries, or power supplies – the WQSensor
gets its power from the USB port, and data is displayed in real-time directly on the computer monitor. When con-
nected, the sensor’s unique ID is automatically recognized, and the most recent calibration, factory calibration,
and probe status are displayed. These quality sensors, bundled with a versatile software package, ensure afford-
able data with minimal effort.

FEATURES
WQSensors
Constructed with impact resistant polycarbonate, gel electrolyte,
double junction, and full range glass, WQSensors are ready for
thousands of measurements. An integral temperature sensor auto-
matically compensates readings for sample temperature, and an
internally stored unique ID and GLP file ensures quality data and
tracks calibration and sensor status.

WQSensors Software
WQSensors software facilitates sensor connection to a Windows
based computer and offers basic data collection capability. When
connected, the sensor’s unique ID is automatically recognized, and
the internally stored GLP (Good Laboratory Practice) file is opened
on the computer. The most recent calibration, factory calibration,
and probe status are displayed. WQSensors PRO software offers a
complete and versatile data collection, processing, reporting, and
graphical representation package for improved productivity and
professional water quality measurements.                                                                        ISE
Dissolved Oxygen/Temperature WQSensor                                        Dissolved Oxygen ⁄                 WQSensor
Based on the US EPA approved method (360.1), the WQ-DO sensor                Temperature
is designed for laboratory accuracy. Probe maintenance is minimal            WQSensor
and simple with a screw-on cap membrane.

Temperature WQSensor
Constructed of chemically resistant stainless steel and Santoprene™
elastomer, the WQ-TEMP offers precision measurements over a
broad temperature range.

ISE WQSensors                                                                                     Temperature
The ISE WQSensors are Ion Selective Electrodes (ISE), an industry                                 WQSensor
standard method that has been proven to provide accurate data
measurements. These replaceable tip sensors offer ion specific meas-
urements.
