Electro-Chemical Devices (ECD) SMS22 - Manual (Page 16)

2.4 INSTALLING the SENSORS
The SMS-22 is supplied with the sensor cables pre-wired to the analyzer. Simply install the sensors in the
flow cell as described below.
The Sulfide and pH sensors mount in the Flow Cell using the supplied ¾” compression gland fittings.
Remove the protective cap(s) from the sensors and save them for future use. The cap contains a
potassium chloride solution, use care when removing the cap from the sensor to avoid spillage. Loosen
the compression fitting on the flow cell to allow the sensor to be inserted into the fitting. Insert the
sensor into the fitting using a twisting motion. There is a swage type seal and an o-ring seal inside the
fitting, the twisting motion will facilitate passing these seals. Gently slide the sensor to the bottom of the
flow cell and hand tighten the compression nut to fix the sensor’s position. Repeat the same installation
process for the other sensor.
The SMS-22 instrument and sensors were calibrated at the factory and should be ready for use when
assembled. However, changes may have occurred during shipping and storage that require recalibration.
