Preface
Please read this manual carefully before use.
Only properly skilled authorized personnel should carry out installation, setup and operation. Ensure that the power cable is physically separated from the power supply during the initial wiring connection or repair.
For example,
- Apparent damage to the sensor
- The sensor does not work properly or provides specified measurements
- The sensor has been stored for a long time in an environment where the temperature exceeds 70°C
Safety Information
■ De-pressurize and vent system prior to installation or removal
■ Confirm chemical compatibility before use
■ DO NOT exceed maximum temperature or pressure specifications
■ DO NOT alter product construction
■ ALWAYS wear safety goggles or face-shield during installation and/or service
Warning | Caution | Danger
Indicates a potential hazard. Failure to follow all warnings may lead to equipment damage, injury, or death.
Note | Technical Notes
Highlights additional information or detailed procedure.
Hand Tighten Only
Over tightening may permanently damage product threads and lead to failure of the retaining nut.
Do Not Use Tools
Use of tool(s) may damage produced beyond repair and potentially void product warranty.
Personal Protective Equipment (PPE)
Always utilize the most appropriate PPE during installation and service of Truflo products.
Preparation before measurement
The conductivity sensor has been factory calibrated. Initial on-site calibration should not be necessary. When measuring high-purity water, avoid pollution, correctly select the constant of conductivity electrode, and preferably adopt the sealed and flowing measurement method.
Otherwise, the conductivity value will increase quickly, because the carbon dioxide in the air will become conductive carbonate ions after being dissolved in high-purity water, which will affect the measured value.
If calibration is required, please follow these steps:
- The conductivity electrode shall be rinsed twice with deionized water [or distilled water) less than 0.5us/cm before use, and then rinsed with the tested sample before measurement.
- The value displayed by the instrument after measurement has been converted to the measured value at 25°C. If no compensation is needed, unplug the temperature electrode and the instrument displays 25°C. The measured value is the conductance value of the solution at that time.
- The conductivity standard provides the simplest and most accurate method for calibrating conductivity sensors. Select a conductivity standard whose concentration is close to or higher than the expected sample concentration.
- The conductivity standard can be used to verify whether the conductivity sensor responds correctly.
Re-calibration Procedure
- Prepare a calibrated beaker of appropriate size, which will allow you to completely immerse the conductivity sensor tip.
- Check to determine if there are any deposits on the electrode sensing area. If the sensing surface (platinum black) is coated, clean the sensor before continuing. Flush the sensor reaction area with distilled water.
- Rinse the calibration beaker with some standard solutions, and then pour the selected conductivity standard solution into the calibration beaker.
- Immerse the electrode and ensure that the sensing area of the electrode is completely immersed in water. If there is a vent hole in the sensing area, the electrode must be submerged under the vent hole. Shake sensor to ensure that trapped air bubbles are released from sensing area
a) Bubbles in the control area of the conductivity electrode will cause serious interference to the ion flow and will lead to erroneous readings.
b) When measuring high-purity water, avoid exposure to CO2, correctly select the constant of conductivity electrode.
c) The recommended procedure is to adopt the sealed and flowing measurement method.
5. Enter the standard value of the standard used from the menu. - Start calibration. Wait for the reading to stabilize, and then adjust the reading to the temperature compensation value of the conductivity standard.
NOTE:
a) Please refer to supporting instruments for specific calibration process.
b) Repeat the process to ensure that the calibration is correct.
ProCon® C Series — Conductivity | TDS | Salinity | Resistivity Sensors
Tough but sensitive — High performance, industrial strength sensors for harsh applications from 0µS – 2,000mS
Measuring specific conductivity of aqueous solutions is becoming increasingly important for determining impurities in water. The ProCon®C series conductivity sensors have been proven to operate seamlessly in industrial process applications.
The ProCon ® line of analytical sensors have been designed for difficult industrial applications and to outperform even in extreme conditions.
The 2-wire 4-20mA, 4-wire or 4-20mA + RS485 output options simplify calibration and communication with remote displays and controllers.

Typical Installation
Maintenance of conductive electrode
Cleaning of conductive electrode
- The organic component contamination on the electrode can be cleaned with warm water containing detergent, or it can be cleaned with alcohol.
- Calcium and magnesium precipitates are best cleaned with 10% citric acid.
- The bright platinum electrode can be mechanically cleaned with a soft brush. Ensure that no nicks or scratches are made on the electrode sensor.
Do Not use a screwdriver or sharp object to clean the electrode surface - The platinum electrode plated with platinum black should only be cleaned using the chemical method. The coating (platinum black) on the electrode surface will be damaged if cleaning with a soft brush.
Warranty
Icon Process Controls warrants this product to be free from significant deviations in material and workmanship for a period of one year from the date of purchase. If repair is necessary and has not been the result of abuse or misuse within the warranty period, please return to Icon Process Controls and amendment will be made without any charge. Icon Process Controls Customer Service Center will determine if product problem is due to deviations or customer abuse. Out of warranty products will be repaired on a charge basis.
Authorization must be obtained from Icon Process Controls Customer Service Center to issue a RIR number before returning items for any reason. When applying for authorization, please include date requiring the reason of return. Instruments must be carefully packed to prevent damage in shipment and insured against possible damage or loss. Icon Process Controls will not be responsible for any damage resulting from careless or insufficient packing.
