Technology
Flow independent operation
Our Chlorine sensor is unaffected by flow velocity changes from 0 to 12 f/s. (HSI 06, 2020). This sensor style has an integrated pump, which uses a long-life brushless motor to deliver a fixed velocity across the electrodes, creating flow independence. The high velocity flow across the electrodes also improves sensitivity and improves the Signal to Noise Ratio.
- Provides internal flow within sensor using magnetic pump
- Agitates plastic balls that continuously clean the electrodes
- Long life Brushless DC Motor

Chlorine Sensor for Drinking Water Distribution Systems
Drinking water distribution systems present special challenges for residual chlorine monitoring. Below is a list of some characteristics of HSI’s new sensor based on its Seawater Platform:
- Low cost of operation
- Long-term unattended operation
- Operation and accuracy at varrying flow rates
- No discharge of reagents or a waste stream
- Reliable performance
- Connection to SCADA system
- Hot Tap Installation for immersion into a pipe
- Life-time chlorine sensor
- Long interval between calibrations
- Differential pH sensor ( with 2 to 3 year life)
- Low initial cost
Self-Cleaning Amperometric Chlorine Sensor
The Only Self-Cleaning TRO Sensor
An electrochemical cleaning method resists polarization and adsorption of organics. Cleaning beads continuously clean the sensor. This keeps the electrode surfaces, including the pH sensor, free from buildup of hardness and biofouling. Solid metal electrodes last the life of the system.
- Provides internal flow within sensor using magnetic pump
- Agitates plastic balls continuously cleaning the electrodes
- Long life Brushless DC Motor
Robust pH Sensor
- Our pH sensor is the only commercially available (non-ISFET) pH sensor that does not require wet storage
- It is the only pH sensor that can withstand -0.7 bar and 10 bar
- The sensor wets rapidly and is accurate within 2 minutes
- The self-cleaning system also keeps the pH sensor clean
