Product presentation at the WQA 2012 show about Sensafe™ Water Metals Check. Sensafe™ Water Metals Check visual test strips are a fast, easy, accurate and inexpensive way to determine if metals are in drinking water. This patented test incorporates a unique aperture (window) indicator that develops red in the presence of +2 metals. The technology eliminates color “bleeding” and gives better results with greater sensitivity. These strips are safe and easy to use with a built in noncarcinogenic pad indicator.

1. Testing for Metals in Water

2. Water
Ø It’s the most important natural resource in
our environment
Ø Not pure - contains microorganisms,
dissolved minerals and metals which need
to be controlled so water can be used
safely

3. Testing for Metals
Ø Most reliable method for testing is
laboratory analysis by instrumentation but
cost per test expensive (over $20) and
must allow for a delay in results
Ø Hazardous reagents in field kits and
complicated test procedure may
discourage the use of the kit
Ø Typical field kits don’t meet EPA detection
requirements such as 15 µg/L for Lead

4. How Metal gets into Water
Ø Leaching from Pipes
Ø Leaching from Pipe
fittings
Ø Leaching from Pipe
solder

5. SenSafe™ Water Metals Check
#480309
Ø Excellent for field
testing metals in water
Ø Easy and Safe
Ø Results in under
3 minutes
Ø Inexpensive way to
increase RO sales

6. Benefits of SenSafe™
Water Metals Check
#480309
Ø 80% of tap water reads
50 ppb or above for
metals
Ø Filtered, RO and Bottled
water is below 10 ppb
Ø Water Metals Check
requires no external
chemicals or any training

7. Procedure of SenSafe Water
Metals Check
#480309
Ø Dip the strip for 30
seconds in sample
Ø Wait two minutes
Ø Match color on the
end of the strip to the
color chart provided
on the bottle (color
chart)

8. SenSafe™ Water Metals Check
#480309
Ø Each strip tests for all +2 metals:
• Cadmium
• Cobalt
• Copper
• Iron (reduced form ONLY)
• Lead
• Mercury
• Nickel
• Zinc

10. Benefits of SenSafe™
Water Metals Check
#480309
Ø Accurate because:
l No chemicals to mix and no
instrumentation to calibrate,
SenSafe™ Water Metals
Check minimizes error
because of simple procedure
l Patented aperture strip allows
such low detection
l Indicator is water insoluble

11. Benefits of SenSafe™
Water Metals Check
#480309
Ø Easy because:
l Professional accuracy for
non-technical user with no
special training needed

12. Benefits of SenSafe™
Water Metals Check
#480309
Ø Quick because:
l No set up is required so
results are available in a
fraction of the time required
by other methods

13. Benefits of SenSafe™
Water Metals Check
#480309
Ø Safe because:
l SenSafe™ Water Metals
Check is classified by OSHA
to be non-hazardous because
of the small amount of
chemicals involved
l Indicator is not toxic

14. Benefits of SenSafe™
Water Metals Check
#480309
Ø Safe to Transport because:
l Small and portable - makes it
ideal for field testing
l Very Stable even when
exposed to elevated
temperatures

15. Why Test Results are Good
1. Test range is acceptable
2. Test is appropriate for user technical
ability
3. Test is robust: reagents are reliable and
stable
4. Test gives meaningful results
5. Test is accurate when performed
correctly

16. Running TEST KIT
IN A LAB
Ø Analysis will provide good results in a
Laboratory setting
Ø A lab is a controlled environment
where Reagent stability is assured
Ø Recalibration of test kit reagents or kit
performance can be easily confirmed

17. Running a Test Kit
On-Site
Ø Test kits and instruments on-site operate under
different environmental conditions
Ø Customer home or business can have a great
deal of affect on results and operator
Ø Distractions like noise and activity
Ø For some tests (especially Liquid reagents)
stability is affected by elevated Temperature in
transport vehicle
Ø On-site (Field) precise results are a challenge
Ø Easy, non-technical procedures are desirable
