Typical Use of Sensor

The Mantis pH Probe can be used to measure pH in many of your science projects.  The probe is very robust but a few situations should be avoided with the pH probe:

  • NEVER submerge the plastic sensor end (the corded end) in any liquid as it is not waterproof
  • NEVER exceed the 80⁰ C maximum temperature or you may permanently damage the probe
  • NEVER store the sensor electrode in distilled water
  • NEVER store the sensor electrode dry
  • NEVER use the sensor in an acid or base solution with a concentration of more than 1.0 molar

Some things you should do:

  • ALWAYS keep the plastic end of the sensor dry
  • ALWAYS rinse the sensor tip with distilled water before performing your experiment.  If electrode bead or diaphragm is occluded or contaminated, the following reagents may be used.
    • For fatty or oily product, tensed cleaner.
    • For calcium and sulfide deposits and metal hydroxide coating dilute hydrochloric acid (10%)
    • For material with protein content a cleaning mixture of hydrochloric acid (10%) and pepsin (saturated).
  • ALWAYS follow the storage recommendations for the pH probe and keep the sensor electrode stored in a pH 4 buffer/KCl (potassium chloride)

The pH Probe is ideal for experiments in the chemistry lab, biology lab or physics lab.  The probe is also ideal in gathering data outside of a lab situation!

  • Measuring pH in a lake or river or a lab sample
How do I connect the pH probe to the Mantis Unit?

Connecting the pH probe

To connect the pH probe to the Mantis Unit, you will need the Mantis Unit powered ON and the pH probe. Make sure no other sensors are plugged into the green colored port on the Mantis Unit.

Step 1 – Locate the green colored port for the Mantis Unit.










Step 2 – Locate the alignment arrow on the pH probe connection end.



Step 3 – Gently connect the pH sensor to the green colored port on the Mantis Unit with the alignment arrow aligned correctly with the sensor port. Make sure the pins and index arrow are correctly aligned, as damage may occur if the connectors are not aligned properly.


Step 4 – Firmly connect the pH sensor to the green colored port on the Mantis Unit when the alignment has been achieved. The pH sensor is now ready to be used to collect your data!
