Product Questions

Is this something that can be reused indefinitely, or will the ingredients degrade with time? Thanks Alan Ray
Question by: Alan Ray Charles on May 10, 2016 9:32:00 AM
Great question! Hanna's alkalinity reagent has a shelf life of roughly 2 years from the date of manufacture, each bottle will have an expiration date printed on the label.

How many tests come in a kit? Does each type of kit have the same number of tests? ie: calcium , alkalinity, phosphate, nitrate
Question by: Nikki Gautreau on May 24, 2016 1:06:00 PM
The Alkalinity standards kit includes one sample of A and B standards for calibration.

  • It's within range By icebrg5 on 1/9/2016

    Tested it twice and came up at 94ppm which is within the range of the
    of the instructions.Test says when at 25 Celsius as well which is 77 F and i tested it and my normal house setting is 72 F. Not really sure if that would have made and difference or not but i will retest when summer gets closer and the heat gets turned off and the temp of the house gets closer to 77 F. Also another thing i would like to point out is that i could not close the hanna checker all the way with either test vile inside it.It would not click shut like it normally does. Obviously something is different about the test viles that makes the checker not able to close all the way.Not sure if that affected the results either.
  • wrong range control for this application. By David on 3/21/2015

    The control is 100 when the range we will be testing most often is 125-150. Why wouldnt you make the control in the desired range? Other than that it is easy to use and give at least a little comfort that nothing has changed with your unit.
  • Great Product - Easy to Use By analyze this on 12/12/2014

    This calibration is super easy to use and gives me the peace of mind that my Hanna ALK Checker is calibrated. Both containers are pre-filled so all you have to do is insert the clear vile when C1 appears and insert the colored vile when C2 appears. Simple!
