Test the water quality

Some TDS meters require calibration before use. For best results, calibrate the meter at 25.0°C (77°F). Refer to the
instructions supplied with the TDS meter.

Utility and well water quality can change over time. Hypertherm recommends regular testing.
Required tools, materials, and parts
pH tester
Silica test kit
Water hardness (calcium carbonate) test kit
13897 TDS meter
Container for water sample
1. Collect a sample of water. Make sure that the water is clear, odorless, and free of biological materials.
2. Test the pH. The ideal pH measurement is between 6.0 and 8.0.
3. Test the silica (SiO2) content. Silica content must be lower than 0.0015% (15 parts per million [ppm]).
4. Test the water hardness. The result must be equal to or lower than 0.006% (60 ppm).
5. Test the TDS concentration. The ideal range is 0.005% to 0.015% (50 to 150 ppm).
 A TDS level lower than 0.005% (50 ppm) can harm waterjet parts and requires the use of nonmetallic or
stainless steel fittings.
 Treat water with a TDS level higher than 0.015% (150 ppm) with reverse osmosis or consider using deionized
water.
CAUTION
Water at or below 0.005% (50 ppm) can damage stainless steel waterjet parts.
Unacceptable
less than 0.005%
(50 ppm)
Ideal
0.005% to 0.015%
(50 ppm to 150 ppm)
Acceptable
0.015% to 0.022%
(150 ppm to 220 ppm)
Unacceptable
more than
0.022%
(220 ppm)
Use nonmetallic or
stainless steel
fittings. Consider using a reverse
osmosis system to
remove TDS. Use a reverse
osmosis system
to remove TDS.
