Portable pH Meter PM-130 offers a big screen to display readings in an extended range from -2 to 20 pH and simultaneously shows temperature from -5.0 to 130°C and ORP from -2000 to 2000 mV.
Design with equipment protection casing. This included a multi-parameter electrode that has a built-in temperature sensor. No additional temperature probe is required. Similarly, the electrode has a mini amplifier to reduce measurements resistant to noise and electrical interference.
Automatic buffer recognition of buffer groups including DIN, NIST, GB compliance. Offer 1 to 5 calibration points with automatic and manual temperature compensation. The ORP scale of this meter can be used with the pH and temperature electrode to check the condition of the pH electrode.
