IK-765SS-SO3 Panel Features
The IK-765SS-SO3 is a dual-parameter inline water analyzer specifically designed as a
‘Turn-Key’monitoring solution for clean water applications to monitor Sulfite in water
commonly used in water and process applications for scavenging of Chlorine and Oxygen.
The IK-765SS-SO3 offers highly accurate, real-time measurement, display and data-
logging of Sulfite (SO3), pH and Temperature utilizing proprietary Pyxis Lab smart sensor
technology, coupled with a Pyxis UC-80 touch screen display and data logging terminal.
The IK-765 series is offered in a convenient and easy to integrate panel mounted format
for rapid installation and simple maintenance.
Features
•Pyxis Lab’s advanced research and development sensor technologies to achieve highly accurate and stable measurement of
Sulfite, pH, and Temperature.
•Pyxis ST-765SS-SO3 is a three-parameter composite sensor used for the measurement Sulfite, pH, and temperature in
compliance with USEPA 334.0 and ISO-7393 guidelines. The sensors advanced PCB offers built-in temperature and pH
parameter compensation (up to pH 9.0+) algorithms eliminating the need for a supplemental pH sensor and controller.
Unique Bare-Gold electrode technology for Sulfite measurement eliminates membranes and electrode solution
replenishment commonly associated with conventional sensors. The ST-765SS Series has a uniquely designed flat bubble pH
electrode design for reduced fouling potential. Reduce your maintenance and cost versus conventional electrochemical
sensors by utilizing Pyxis replaceable Electrode Head (EH-765) for this sensor allowing for years of reliable service. The ST-
765SS Series may be calibrated in-situ after cleaning via DPD or similar Sulfite wet chemistry test measurement of active
sample.
•Pyxis ST-007 Single-Sensor inline stainless steel flow cell provides an Sulfite demand-free environment for the safe
installation and accurate operation of the ST-765SS-SO3 sensor. The inlet and outlet to the ST-007 are 316L stainless
steel with SwageLok fittings in ¼-inch OD. The IK-765SS-SO3 panel is also equipped with inlet PRV, Rotameter and digital
Hall Effect inlet flow meter for precise control and recording of the recommended flow range of 200-400 mL/minute. The
outlet flow should be diverted to drain or the inlet of the pretreatment system for those desiring NSF compliance.
•Simple sensor removal and replacement. The ST-765SS Series sensors are connected to the display/data logger via RS-485
Modbus (RTU) allowing for integrated sensor calibration interface and diagnostics within the display screen.
•Convenient and simple to install Back-Panel (IK-765) for rapid and easy installation. Truly a plumb and power to go
platform with intense factory setup, testing and sensor calibration prior to shipment.
•UC-80 touch screen color display/data logger prewired to the Pyxis sensor via RS-485 with calibration interface. Display/data
logger offers 2x 4-20mA, RS-485 and TCP Modbus output with remote diagnosis and parameter adjustment. Pyxis
PowerCloudTM 4G Gateway available as an optional accessory.

the pH portion of the ST-765SS-SO3 sensor as desired.
Figure. 16 - pH Calibration

- 11 -
Single Point pH Calibration
Remove the ST-765SS-SO3 sensor and rinse 3x with DI water. Submerge the sensor into a beaker with pH=7 buffer solution.
Click "pH7 calibration". A dialog box will pop up to confirm whether to perform this operation, click "OK" if the calibration
operation is confirmed, if the calibration is successful the dialog box will show "calibration success".
Figure. 17 - pH Calibration Success Prompt
Two Point pH Calibration
Remove the ST-765SS-SO3 sensor and rinse 3x with DI water. Submerge the sensor into a beaker with pH=7 buffer solution.
Click "pH7 calibration". A dialog box will pop up to confirm whether to perform this operation, click "OK" if the calibration
operation is confirmed, if the calibration is successful the dialog box will show "calibration success".
After pH7 is successfully calibrated, you can choose acid calibration or alkali calibration for the second calibration point. If
you choose acid calibration, clean beaker 3x with deionized water. Fill the beaker with pH=4 buffer solution. Enter the value
4 in the calibration value dialog box, and click "Acid Calibration", then a dialog box will pop up to confirm whether to perform
this operation. Click "OK" if the calibration operation is confirmed and the dialog box will show "Calibration Successful" if
the calibration is successful. Similarly, a pH=10 buffer solution can be selected for the second point calibration if desired.
Three Point pH Calibration
Remove the ST-765SS-SO3 sensor and rinse 3x with DI water. Submerge the sensor into a beaker with pH=7 buffer solution.
Click "pH7 calibration". A dialog box will pop up to confirm whether to perform this operation, click "OK" if the calibration
operation is confirmed, if the calibration is successful the dialog box will show "calibration success".
After pH7 is successfully calibrated, you can choose acid calibration or alkali calibration for the second calibration point. If
you choose acid calibration, clean the beaker 3x with deionized water. Fill the beaker with pH=4 buffer solution. Enter the
value 4 in the calibration value dialog box, and click "Acid Calibration", then a dialog box will pop up to confirm whether to
perform this operation. Click "OK" if the calibration operation is confirmed and the dialog box will show "Calibration
Successful" if the calibration is successful.
After successful acid calibration, select pH=10 for alkali calibration. Clean the beaker 3x with deionized water. Fill the beaker
with pH=10 buffer solution. Enter the value 10 in the calibration value dialog box, and click "Alkali Calibration", then a dialog
box will pop up to confirm whether to perform this operation. Click "OK" if the calibration operation is confirmed and the
dialog box will show "Calibration Successful" if the calibration is successful. The three-point calibration is completed.

4.6.2. SO3 Calibration
The measurement module of the ST-765SS-SO3 sensor is thoroughly calibrated at the Pyxis Lab factory. To calibrate, the
user can perform a single point calibration according to the requirements of the application.
Calibration of the ST-765SS-SO3 sensor for Sulfite should be done with the sensor inline exposed to active flowing sample
water. Use titration, colorimeter or fluorometer methods (i.e. Pyxis SP-800 / SP-910, Hach DR-1300 or similar) to test the
active (flowing) water sample in the flow tee assembly of the IK-765SS-SO3 panel. Once you have tested and confirmed the
Sulfite concentration value in the active (flowing) flow tee assembly, enter the recorded test result value in Calibration
Screen and click "High Cal". A dialog box will pop up to confirm whether to perform this operation. If the calibration
operation is confirmed, click "OK", and if the calibration is successful, the dialog box will show "Calibration Success".
*NOTE* Click the restore button in the calibration interface of each sensor to restore the data of pH/residual SO3 sensor. If
a user error is made during calibration and other operations, you may restore the factory settings of the sensor through the
restore function.
