Detailed Pipe Tee Installation Instructions 
 

1. 

Wiring:  

a.  Route the cable – either through conduit or on a cable tray. 

b.  Insert the sensor cable into the Alpha pH2000D controller through a watertight 

cord grip.  Conduit holes are provided for the cord grip on the bottom of the Alpha 

pH2000D controller.   

c.  Connect the sensor wires into the Alpha pH2000D sensor terminal block as shown 

in the Alpha pH2000D manual. 

 

2. 

Calibrate: 

a.  Power the Alpha pH2000D controller. 

b.  Remove the protective cap from the sensor head and make sure moisture is 

present and that the salt bridge has not dried out.  If the protective cap is dry, the 

sensor should be hydrated in tap water for at least 1 hour prior to calibration. 

c.  Calibrate the pH sensor as explained in the Alpha pH2000D manual.  It is 

recommended to use a 2-point buffer calibration on installation of the sensor.  
Subsequent calibrations should be scheduled based on process demands. 

d.  If measurement response time is slow or if the sensor will not calibrate, refer to 

Section 4 for maintenance, refurbishment and troubleshooting suggestions. 

 

3. 

Mount: 

a.  Apply Teflon

®

 tape to the sensor body threads. 

b.  Insert the sensor into the tee and slowly turn clockwise until secure.  Tighten the 

sensor with a wrench until snug to prevent leaking.  Be sure the pipe remains full 
when the sensors are installed.
