Choosing the tester
Compare it with the pHep5 if you need a finer pH display step and its different accuracy specification. Both models measure temperature, but their pH resolution and calibration options should be checked individually.
pH and alkalinity are different measurements. For freshwater buffering capacity, see the HI775 alkalinity Checker. Keeping both readings clearly labelled is more useful than trying to compare their numbers directly.
What is included?
The supplied tester includes the HI73127 pH electrode, HI73128 removal tool, batteries and instructions.
Calibration and electrode care
Calibrate with fresh buffers recognised by the instrument, choosing the points for your expected measuring range. See pH 4.01 and 7.01 buffer sachets and check whether your method requires other buffer values.
Keep the electrode clean and store it as instructed. HI7061M general cleaning solution and HI70300M storage solution do different jobs; use the product specified for the probe and follow the relevant method.
Taking repeatable pond readings
Use a representative sample and wait for the reading to stabilise as the manual directs. Record the time and the temperature where available, so you can compare later measurements on a useful basis.
A pocket sample tester is used for spot checks. Choose a suitable monitoring system if your routine needs readings or alerts between visits.
