@jeffissimo I am also a technician at Pine, the read button on the Hach 2100Q does not fall off! It is a rubberized keypad like a TV remote or any membrane inside a keypad! What generally happens is the read key is used more than the other keys on the keypad. Sharp fingernails or a pen is sometimes used, and tears, through the plastic! In normal use it could last a five or more years. Now the 750 dollars flat fee can fix any issues with the Hach including replacing the cover, but if your unit breaks through the read button, you can order a new cover for under 50 dollars and replace yourself, 5 screws on the bottom must be removed, use a heat gun all around the edges and while hot, poke a small flat screwdriver on the top edge and pry open careful not to disturb board or aluminum sheets inside, then simply replace cover and replace 5 screws!
Thanks for posting this video. It was thorough yet concise and explains the calibration method wonderfully. I am looking for a turbidimeter myself, for a capstone project, and I am torn between the Hach 2100 and another EPA approved meter. I was wondering if you could share some thoughts on the build quality of the unit. I keep seeing a few reviews of the unit that describe the Read button falling off and Hach charging nearly $700 to repair the button. With only a 1 yr warranty that is worrisome. Other manufacturers offer a 2yr warranty. Any thoughts you can share to the build quality will be greatly appreciated. Thanks.
