I should have just returned this to Amazon... I deal with water quality testing equipment every month at work and wanted to get some gear of my own to help with a local river keeper group. I purchase this unit from Amazon and I never could get it to calibrate. I'm familiar with calibration methods of other brands of meters in this one was very similar but the problem is it would never read correctly so it could never be calibrated correctly. I the mistake of trying to contact the manufacturer I really wanted to make it work. The meter would not calibrate so I spent weeks returning emails trying to troubleshoot it with the manufacturer and eventually they said they would send me another one but it has been almost a month and they will not return my emails anymore so I guess I was just promised a replacement that I will never get. Horrible experience with the manufacturer I would not buy this ever again. If you get a defective unit you might want to send it back to Amazon ASAP and not deal with the manufacturer.

Have used this in extreme environments for 6 months. No problems, but display font is too small.
