calibrating buffers, case, and batteries.
These compact, waterproof pH meters can measure samples as small as one drop. The virtually unbreakable sensor eliminates breakage problems associated with fragile glass pH sensors.

Q:Would this meter be a good choice for daily measuring of the pH level in a swimming pool?
A:Yes, as long as the sensor (of this or any other pocket pH tester) is rinsed off after testing this unit would work well to test swimming pool pH.
Q:Could this tester be used to test bar soap directly? Or should the soap be in solution?
A:This unit does not have a probe that would insert into the bar, and would not work well then to test it. If the soap was in solution this meter would work. Even ISFET probes with insertion type probes would have a hard time taking the reading of hard bar soap without any water or liquid to transfer ions through.
Q:Is this unit capable of measuring pH in very low conductivity, high viscosity corn syrup?
A:Measuring pH is non-aqueous solutions is never easy to accomplish. This probe would not be the best for that application. Consider instead using a sleeve junction electrode such as 58820-59. There are other ways to help improve the quality of aqueous measurements including creating non-aqueous calibration buffers and changing the internal filling solution of your electrode to a non-aqueous solvent.

Q:I am going to be canning acidified foods. Which meter do you recommend.
A:This is a good choice for measuring the pH of foods. The stainless steel probe is easy to clean and won't leave any chemical residues that traditional pH probes do.
Q:What is the accuracy in the 1.8- 2.8 pH range.
A:The range for this unit is listed as 2-12 pH. The accuracy within that full range is +/-0.1pH. The unit may be able to read below 2 pH, however, we do not have accuracy information outside of its listed range. To work with lower pH values, I suggest looking into our 59540-22. This is a meter and ISFET probe with a range from 0 to 14pH.
Q:Is this meter suitable for testing the pH of canning? Can it do hot ingredients?
A:This can be used to take the pH of semi-solids (cheese, jell-o, etc) and liquids. The highest temperature this unit can handle is 104F or 40C, warm but not hot.
Q:Is this meter suitable for direct soil pH testing, or does the soil have to be combined with water to form a slurry?
A:We recommend that this pH probe be used with a slurry. Please see the following procedure:
