LaMotte CORROSION CONTROL Test Kit - Manual (Page 14)

CALCIUM HARDNESS STANDARD · CODE 6185
Fill 100 mL volumetric flask to 1
2
volume with Deionized water. Use pipet
to dispense 10 mL of standard into flask. Dilute to volume and mix.
Diluted standard = 100 ppm Calcium Hardness
PHOSPHATE STANDARD · CODE 6184
Prepare two 100 mL volumetric flasks by filling to 1
2
volume with distilled
water. Use pipet to dispense 10 mL of standard to first flask. Dilute to
volume and mix. Use another pipet to dispense 6 mL from first flask into
second flask. Dilute to volume and mix.
Diluted standard = 6 ppm Phosphate
pH BUFFER 7.0 · CODE 2881
pH Buffer 7.0 is provided with each kit and should be used periodically to
check the performance of the tester. Other buffer solutions can be provided
to cover different pH ranges of interest.
TDS
TDS solutions can be selected from a list of different strengths:
74 MMHOS (52 ppm) – Code 6416
718 MMHOS (503 ppm) – Code 6417
1413 MMHOS (989 ppm) – Code 6354
Following the instructions for the tester, periodically check the response of
the tester to guarantee proper performance.
TEMPERATURE
The thermometer (Code 1066) should be periodically checked against a
reference thermometer that is NIST certified. Any deviation from the
reference temperature should be noted.
