2、 Sensor electrode:

Sensor electrodes are consumable parts with certain performance differences, and there are multiple models to choose from. Choosing the right one is important for measurement; The main factors considered include: temperature of the measured medium, acidity or corrosiveness of the medium, ordinary water quality or organic matter, solution viscosity, presence of particulate matter in the solution, and special media; We also need to consider the on-site installation requirements and sensor structure.

2.1Basic electrode types:P026WP3type/P891Type used for measuring ordinary media or wastewater0～60℃，P026GP3Type corrosion-resistant, suitable for measuring in sewage or high temperature conditions0-100℃；

P026CP3type/C491Type used for pure water measurement0～80℃, suitable for power plants, etc.

2.2 ORPPtypeORPElectrode is used forORPmeasurementmVValue.

2.3Special solution medium electrode model:P026GTP3Antimony electrodes are corrosion-resistant and resistant to particulate matter;P026TLP3Special electrodes for desulfurization and denitrification are resistant to viscosity and particulate matter;P 026 ggyp 3Type electrodes are used for measuring media such as organic compounds, oxidizing liquids, and hydrogenation liquids.

2.4Digital Sensor Electrode Series: No display instrument required, direct electrode output4-20mA, andRS485The digital signal is directly connected to the display device.

2.5The above electrodes are subjected to water sample pressure:0.5MPa.

2.6There are various installation methods for electrodes, such as flow type, pipeline type, and insertion type, and special installation methods can be customized.
