The meter comes with a replaceable glass bulb probe (PH60-E) for liquid's pH testing. It is also compatible with 3 other pH probes and an ORP probe (sold seperately) for different applications such as solid samples and surface test. The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards. NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode like our LabSen 803 Electrode. Do NOT store the probe in distilled water or deionized water because they will cause damage to the pH probe. Only use distilled water for rinsing the pH probe.
