Chlorine Analyzers Waste 6.1 Billion Gallons of Non-Revenue Water
Traditional sensors waste 70,000–138,000 gallons of treated water per sensor per year. Across the U.S. this totals 6.1 billion gallons annually. The MP5 eliminates this entirely with direct in-pipe installation.

MP5-A: A New Standard in Accuracy
Calibrated once at pH 8.0, the MP5-A held ±4% accuracy as pH varied from 6.5 to 8.5, temperature from 10–35°C, and conductivity from 156–10,000 µS. Limit of detection 0.01 ppm — 3× better than Hach CL10f.

Sensors Are the Missing Link for Legionella Control
Legionella causes more hospitalizations than carbon monoxide yet buildings rarely monitor water quality continuously. This paper explains why existing sensors fail in hot water systems and how the MP-HOT changes that.

Measuring Monochloramine Without Reagents
A new control method for chloramination using the MP-TOTAL sensor. Measure free chlorine and monochloramine simultaneously — without reagents, waste streams, or expensive colorimetric equipment — and enable precise breakpoint curve control.

ORP versus Amperometry for Chlorine Measurement
A detailed technical comparison of ORP and amperometric measurement methods for Total Residual Oxidant. Covers ORP electrode poisoning, ±30% concentration error, logarithmic response limitations, seawater baseline variability, and why amperometry is the correct choice for quantitative control.
