REPRESENTATIVE IMAGEWHERE TO START
Make each measurement count.
Treatment-program visibility
Follow compatible disinfectant residuals alongside pH and temperature.
Connected operations
Review controller outputs and integration with your existing controls.
Where will the reading help you act?
Give each water circuit its own monitoring point.
- EVALUATION POINT 1Makeup supply
Establish incoming residual and conductivity.
- EVALUATION POINT 2Recirculating water
Trend the response to dosing and cooling demand.
- EVALUATION POINT 3Blowdown / operator review
Use the treatment program to interpret changes.
Conceptual monitoring sequence. Final placement, detection limits and control actions must be reviewed for your water and equipment.

A few details make
all the difference.
Bring these questions to your application review.
- Which biocide or disinfectant do you use?
- What is the maximum water temperature and conductivity?
- Which BMS or control interface is required?
APPLICATION FIT
Confirm the conditions before you specify.
Confirm chemical compatibility and sensor operating limits. Residual monitoring supports a water management program; it does not detect Legionella or establish compliance by itself.

COMMON SELECTION QUESTIONS
Start with clear answers.
What is the best chlorine analyzer for a cooling tower?
The right choice depends on the treatment chemistry, operating range and installation. Review temperature, conductivity, deposits and the required controls interface before comparing models. A pilot should include normal treatment cycles and changing operating conditions.
Can chlorine monitoring replace ORP monitoring?
Treat them as different measurements. Define whether the operating decision requires a disinfectant residual or an oxidation-reduction potential trend, and review how each fits the treatment program.
Can a chlorine sensor also measure bromine?
Do not infer compatibility from the word chlorine. Confirm the exact oxidant chemistry, sensor configuration and validation evidence with Halogen before specifying a bromine application.
Does residual monitoring detect Legionella?
No. A residual measurement is not a microbiological test. Use it within the facility's complete water management and testing program.
