3.9. Sanitary Probe P60S, P65S, R60S, R65S
a) The P60S is designed with a stainless steel flange to mate with a Tri-Clover ferrule TL14AM7-2-1/2.
3.10. Insertion mounting Series 4 Differential Probes
a) Apply pipe sealant to the electrode end of the probe and screw it into the any standard 1-1/2” Male
NPT.
3.11. Hot/Wet tap insertion mounting Series 7 Differential Probes
Refer to Dwg# N106-79
a) A ball valve assembly, P60-HTC, is available from Water Analytics which includes the assembly and
a safety shroud.
b) Mount the ball valve assembly in a desirable location. The assembly comes with a field selectable,
1-1/4 NPTF or socket adaptor. Make sure valve is in the close position before mounting.
c) Remove the union body by turning the union nut counter clockwise. Take the compression fitting
apart as shown on the drawing. Insert the back end of the series 7 probe through the union body
until safety notch on the probe aligns with the safety stop on the union body.
d) Place the union body, with the probe attached, back into the ball vale assembly and tighten union
nut. Open ball valve & slide the probe into the process.
e) Put the compression fitting components on the probe in the order shown in the drawing and tighten
the nut by hand as much as possible, then turn 1/2 turn with a wrench to keep probe in place.
f) Insert protective shroud as shown.
4. SERVICE AND MAINTENANCE
4.1. Probe Cleaning
a) The probe should be kept reasonably clean to avoid measurement errors. Frequency of cleaning
can only be determined by experience. To clean proceed as follows:
b) Rinse with clean warm water.
c) Soak the end of the probe in warm water and dish detergent for 3 or 4 minutes.
d) Brush the end of the probe, particularly the three electrodes with a soft bristle brush such as a tooth
brush. Take care not to scratch the glass electrode.
e) If the probe is still not clean, it may have to be cleaned with acid. CAUTION: Do not acid clean
probes used in processes containing cyanide solutions. Some experimentation may be required to
determine the most suitable acid for your process. Use the most dilute acid which is effective.
Normally 10 parts of water to one part muriatic acid is sufficient. Do not use hydrofluoric acid.
f) Soak the probe for not more than 5 minutes in the chosen acid; then rinse thoroughly with clean
warm water and soak in water for 3-5 minutes.
g) Calibrate the system in accordance with the instrument instruction manual.
