Milwaukee pH600 pH Meter Pen

SKU: 205456

  • Works well for me, stays in calibration thus far. By Mike on 8/26/2014

    Mine also came coated with a solution that had dried up as well on the probe under the cap. Probably from the manufacturer. Simple rinse and its gone, calibrated it with 7.01 fluid and tested it with 10.01, was dead on. Bought extra solutions to check it from time to time and after 1 month of use has stayed in calibration, very happy with. I rise in freshwater after every use and give a good shake before putting cap back on, its NOT necessary to store in calibration solution contrary to the directions, hence the cap. :)
  • Came covered in salt By Dmitry on 1/19/2014

    Not sure why, but the unit came without any liquid inside (I thought you had to use it to store the probe) but instead it was covered in salt, as if it was already used.
  • Dont buy it By INXS on 11/7/2013

    The meter appears to be accurate as long as you calibrate it before every use. However beware of the 30 day warranty...My tester has already quit working and I have only had it for 4 months !
  • Great By Keith on 7/30/2013

    Way better than going blind trying read those color charts.
  • Don't forget the Calibration solution!!!!! By Lukee on 1/10/2013

    I just ordered this product and then found out I need calibration solution!!!!! Don't forget so you don't have to pay for shipping on a $0.99 product!
  • quick and accurate pH By Paul on 1/2/2013

    Very nice handheld pH meter, compact yet easily read LCD display. Seems to remain quite accurate for me even though I store it dry, with cap on. Used for 4-5 months without calibration, tested it with ph 7 & 10 reference solutions, was only off by .1 with the ph 10 solution.
  • a must By Brian on 6/11/2012

    buy this instead of trying to read color charts on a test kit. be sure to buy some of the 7.0 calbration packs
  • great instrument for the price By Michael on 4/28/2012

    exactly what I've been looking for. easy to calibrate, easy to use, and the price was right for my budget.
  • Accurate, but, loses calibration frequently By Kirk on 3/11/2012

    This pH pen is great for the price, but, it loses its calibration, by as much as 0.8, in just a single day of not using it. I store the probe wet as per the instructions, and when going to check the pH from one day to the next, the unit has lost its calibration. It is almost an entire pH unit off when comparing it to my tanks' pH monitor/controllers (both with new, calibrated probes from the same order as this item was from). Every calibration solution costs you a buck, so, with the need for such frequent calibration, it costs more to use this than a test kit, even though initially, the cost would have been the same as that of a good quality test kit. The calibration screw is a pain to get to as well, as it is on the back of the unit while you are trying to read the front of the unit to set it, and, the screw is not centered in the middle of the recessed hole, so you are forced to put the screwdriver in at an angle to get to it.
  • just a great little meter By Robert on 2/22/2012

    I didn't buy mine (I"ve had 2 so far) at BRS, but I thought I'd throw in my .02 in case anyone is wondering if a $20 ph meter can be worth a crap.

    It totally rocks. I'm utterly baffled at how it keeps so close to calibration -- sometimes for months and months in storage.

    Another poster mentioned 'how do you keep the tip moist'? A: the cap is /supposed/ to be water tight. My experience is 50/50 at this point. The first one I owned was tight as drum. All I did was take a little square of sponge, moisten it w/ tap water (use 7.0 calibration sol. or storage solution if you have 'em) jam it into the cap and then put the top back on. Should keep quite a while that way. Don't forget to turn off the display!!

    The second meter I have, has a looser cap and I find I have to tape it shut and keep it sealed in a baggie to ensure that the tip keeps moist. Bummer but I don't use it that often. I really just keep it around for emergencies and sanity checks. Well worth a twenty, it's come in handy lots of times.
