Ultra-Sensitive Chlorine Detection

RPC Ultra-Low™ test strips measure extremely low levels of total chlorine and chloramines, including values as low as 0.01 ppm — giving clinicians confidence when monitoring pre-treatment water systems and ensuring regulatory compliance in dialysis settings.

Clear, Easy-to-Read Results

Seven color blocks ranging from yellow to blue make it simple to interpret the exact chlorine concentration without specialized instruments. This helps reduce user error and speeds up routine water quality checks.

Specialized Non-DPD Reagent

The Ultra-Low™ strips use a non-DPD reagent that eliminates manganese interference — a common issue with standard chlorine tests — for more accurate readings that dialysis facilities can trust.

Fast & Reliable Testing

Results are typically obtained in 35–80 seconds using an uncomplicated “dip and read” method. The individually wrapped format preserves strip integrity until the moment of use, supporting consistent performance every time.

These features make RPC Ultra-Low™ an essential testing tool for water quality monitoring in dialysis centers, helping ensure that municipal or treated water is free of residual chlorine before it is processed by purification systems.
