WTW VARION® Plus, AmmoLyt® Plus, NitraLyt® Plus: Advanced Ion-Selective Electrodes for Water Analysis
Brand: WTW
Sub-brand: Xylem
Your Perfect Partner for Ammonium and Nitrate Measurement
Key Benefits:
- Very Easy Operation
- Lower Costs
- More Possibilities
This document details the WTW VARION® Plus, AmmoLyt® Plus, and NitraLyt® Plus ion-selective electrode (ISE) sensors, designed for precise and reliable measurement of ammonium and nitrate in various water applications.
Visual Description: The cover image depicts an outdoor water treatment facility with muddy water. Two submersible sensors are visible in the water, connected by cables.
Proven Quality, Surprisingly New
With over 15 years of experience in online ion-selective measurement, WTW offers sophisticated and reliable measurement technology without compromise.
The New Matrix Adjustment: Easier and Faster Than Ever!
The accuracy of ISE measurements depends on the medium being measured. Matrix adjustment compensates for this effect. Benefit from intuitive handling that makes adjustment extremely simple.
Visual Description: A close-up view of a sensor probe, labeled "VARION® Plus", with internal components and connection points visible.
Cross-Compensation: One Electrode, Multiple Sensors
It is now possible to compensate for multiple sensors simultaneously with a single chlorine or potassium electrode. This new function allows for complete compensation of your measurements, potentially saving costs.
Visual Description: A diagram illustrating cross-compensation, showing a sensor with connections for reference, measurement (e.g., NH4+), and compensation (e.g., K+).
Ammonium Measurement, Even in Highly Contaminated Media
Measure high NH4-N concentrations up to 2,000 mg/l in concentrates and other process waters without the need for chemicals.
Visual Description: A close-up view of a sensor probe, labeled "AmmoLyt® Plus", showing its construction and connection points.
Product Line Overview:
VARION® Plus
A multiparametric in-situ probe with a short response time, applicable in various ways. Ideal for rapid ammonium and nitrate measurement with dynamic compensation of potassium and/or chlorine.
Visual Description: A close-up view of a sensor probe, labeled "NitraLyt® Plus", showing its construction and connection points.
AmmoLyt® Plus
A single-parameter in-situ probe for measuring ammonium with dynamic potassium compensation.
NitraLyt® Plus
A single-parameter in-situ probe for measuring nitrate with dynamic chlorine compensation.
Calibration-Free, Easier Than pH Measurement!
WTW's ISE sensors measure directly in the process without the need for adding chemicals or taking samples. Thanks to technological advancements, calibration with standard solutions is obsolete. This ensures stable, long-term measurements with no extra effort. Simply screw in the electrodes; everything else is automatic!
Individual Electrode Replacement
The single-electrode principle of WTW's ISE sensors allows you to replace only what is necessary.
Robust Electrodes
Thanks to the robust WTW ISE electrodes, handling and cleaning the sensors becomes a secondary concern.
Direct Connection to IQ Sensor NET
Benefit from:
- Connection of up to 20 sensors.
- Measurement of all important parameters.
- Maximum communication possibilities.
