I just picked up the Nitrate HR checker and noticed a discrepancy with the timer. I know I've read here or on the BRS facebook page that it has a 7 minute timer. The directions even state "Insert the cuvette into the checker and close the cap. Press and hold the ON/OFF button. The display will show the countdown prior to the measurement. Alternatively, wait 7 minutes and press the button"*
However, the timer on mine only went to three minutes. Reading something about another check (LR Nitrate maybe), I did try holding the button down longer, but that didn't change how long the timer was set for. I also noticed that, as the directions stated, it didn't remain on for 10 minutes. I wasn't paying attention, but it was, at best 2 or 3 minutes, but it seemed like 1 or 2.
So, did they change something with it and not update the directions? Did I get one that was programmed incorrectly (ie incorrect firmware)? Am I misunderstanding the directions? Something else? Unless someone has a difinitive answer or Hanna replies here, I'll probably just email them about it.
On the plus side, part of the reason I bought it is because I've been using salifert for a while and decided to give Nyos a try. Every Nyos test I've done has read zero. Assuming the result on the hanna test was correct at .04, that at least matches what I was getting with Nyos.
*In my expierence, with all my hanna checkers (5 now), when it says 'alternatively, wait X minutes and press the button', X minutes is the length of the timer.
