Introduction The SSM is a patented design that provides a hand

held, automated method for detection of soluble salts.

The Model RPCT-07-001 was performance tested and approved as an alternative method of taking conductivity measurements by the United States Navy. Listed in Standard Item 009-32 FY-10

The US Department of Transportation is in the process of approving the SSM for use.

Process Steps1. Attach meter to surface2. Inject deionized water into measurement chamber

with one press of the dose bottle3. Meter automatically agitates solution (~ 45 seconds)4. Meter automatically takes reading

Displays reading on LCD screen Stores values electronically

5. Wipe remaining water from surface after removing SSM

6. Flush meter by turning over and injecting water from dose bottle.

Summary of Testing Tested by the US Navy in field studies Reduced labor by over 50%

Ease of use-immediate results recorded electronically

Tested by two independent laboratories against the Bresle method and benchmark laboratory grade conductivity meter Concurrent Technologies Corporation (CTC)- February

Corrosion Control Consultants & Labs, Inc. (CCC&L)-April/May 2008

22

Laboratory Test Method 50 test areas were evaluated for 3 different doping

concentrations. 10 doped tests were run on each panel.

A total of 5 panels were used for each concentration.

The center of each identified patch area was doped with 50 µL of solution.

The doped panels were allowed to dry in the laboratory at ambient conditions overnight (~15 hours).

After drying the panels were tested according to the Bresle Test Method.

Conclusion Independent testing demonstrates that both methods

return equivalent results . The mean measured values are almost identical.

The only discernable difference between the two methods is that the SSM has much lower variability in measurements. The variance in SSM measured values is significantly

less than those measured with the Bresle patch.
