For some reason, I was unable to calibrate the HACH meter. The option to check standard for LDO101 would not highlight. I turned the meter off numerous times but got the same result. I did check its accuracy by comparing a result of 1413 micro Siemens/cm against the analytical reagent of 1376. Assuming this result was in the ball park, we went ahead with monitoring.
Four fishermen on the jetty - beautiful, still morning.
