Calibrating pH and CLF Probes for Accurate Pool Measurements

Proper calibration of pH and CLF probes ensures accurate pool water measurements. For pH calibration, use either a pH 7.0 buffer solution or a colorimeter/Pool Tester to measure the pool water pH. Calibration is performed by immersing the probe in the buffer or entering the tester's value into the ASIN AQUA Salt device within a range of 6.4 to 7.8. For CLF probe calibration, measure chlorine concentration with a colorimeter or tester (0.3 to 1.2 mg/l required). If the difference between device and tester readings exceeds 0.2 mg/l, adjust the CLF calibration value accordingly. Repeat measurements after thorough water mixing and allow probe stabilization over several days for best results.
