Why We’re Upgrading from ISE to UV LED Nitrate Probes
For years, at Photonic Measurements, we have relied on Ion-Selective Electrode (ISE) probes to measure nitrate.
They work, but there have been challenges with them, frequent calibrations, membrane swaps and ion interferences.
Smarter, Faster, More Reliable Nitrate Measurement
Our new UV nitrate probes solve these issues and offer a new era of accuracy and efficiency.
The UV Advantage
Feature | ISE Nitrate Probe | UV LED Nitrate Probe |
Calibration | Weekly or more | Monthly or less |
Interference | High (Cl⁻, SO₄²⁻) | Minimal |
Maintenance | Membrane replacement & cleaning | Non-contact, self-cleaning |
Consumables | High ongoing cost | Virtually none |
Accuracy | Moderate in complex water | High & stable |
Longevity & Drift | Significant drift over time | Excellent stability for years |
Key Benefits
More Trustworthy Data
Accurate readings even in complex water chemistry
Better Monitoring
Continuous real-time results for immediate actions to be taken
Cost Savings
Lower total cost due to reduced consumables and labour
Operational Efficiencies
Less downtime with fewer calibrations and maintenance interruptions
Switching to UV LED Nitrate Probes isn’t just a tech upgrade, it’s a smarter way to work.
Reduce hassle, cut costs and trust your data every time.
Ensure more reliable operations and less time fixing problems.
