Quaternary ammonium chloride solutions come in many varieties; ours are calibrated for Oasis 146. Results for others using our strips will still be accurate. 

Quats they have their advantages & disadvantages:

  1. Work best in the pH range of 8-11
  2. Loses potency in hard water (see hard water test strips)
  3. Color charts start to deviate at 45C (110F) & above. See Technical Tab for correcti interpretations.

Follow the directions on the label. All our quat strips are "quick response". In other words, dip the strip & compare to the color chart immediately. If you wait, the color will develop further & give a false high reading.

See the Technical Tab for temperature limits. Do not use water warmer than 40C (105F) as this may give inaccurate readings.

If you are not sure how to dilute your solution, try our Dilution Calculator.

Temperature and QAC strips reading relationship

Temperature vs ppm results for Hyamine 1622 (Fluka) warmed up from 35 to 60oC (95-140F).

T (oC) QAC strips readings at: 0; 50; 100; 200; 400 ppm
35     Readings ok for 0-400ppm
40     Readings ok for 0-400ppm
45     0, 50, 100 ppm readings ok; 200 & 400 ppm read~ 1/2 color square higher
50     50, 100 ppm read~ 1/2 color square higher; 200, 400 ppm read 1 color square higher
55     Readings 1 color square higher across whole range
60     Readings 1 color square higher across whole range
