Why measure pH and ORP in water?
Analysis of pH and ORP levels in water is pivotal for addressing various challenges. pH, indicating acidity or alkalinity, directly influences chemical reactions. Fluctuations can disrupt aquatic ecosystems, impact nutrient availability, and compromise industrial processes. ORP potential, reflecting the water’s oxidative state, is crucial for measuring the efficiency of wastewater treatment and influencing microbial activity. By monitoring these parameters with precision, our pH/ORP/Temperature probe aids in averting environmental imbalances, optimizing industrial processes, and ensuring water quality compliance. It’s an essential control parameter for proactive problem-solving and maintaining the delicate balance of aquatic systems.
Main applications of pH and ORP measurement in water
Aqualabo’s pH probe finds versatile applications crucial for water management across diverse settings. In environmental monitoring, it plays a pivotal role in safeguarding the health of rivers and lakes, ensuring that pH levels support aquatic life. In industrial processes, precise pH and ORP measurements are vital for optimizing chemical reactions, preventing corrosion, and maintaining efficient production. Wastewater treatment benefits from the sensor’s ability to gauge ORP potential, ensuring the effectiveness of treatment processes. Whether it’s ensuring compliance with regulatory standards or preserving the delicate balance of aquatic ecosystems, the pH/ORP probe delivers reliable insights for a range of applications.
Measurement principles of Aqualabo’s pH probe for water quality analysis
Our sensor uses advanced technology with a combined electrode of special glass and a reference of Ag / AgCl in a saturated KCl electrolyte in the form of a plasticized electrolyte “PLASTOGEL”® for pH and ORP measurements. A platinum-tipped electrode provides ORP measurements, while an NTC sensor provides accurate temperature readings for reliable data. The electrolyte communicates directly with the external environment without any capillary or porous intermediary, so there is no risk of clogging or defusing the reference.
Why use and trust Aqualabo’s pH and ORP probe?
Our probe is characterized by its robust design. Highly resistant materials of construction combined with a reliable measurement principle make it the best choice for both spot and on-line applications. The open and universal Modbus RS-485 communication allows seamless integration with third party equipment, while the built-in transmitter ensures interference-free measurement and allows temperature compensation inside the sensor. Easy to use and maintain, the replaceable combined electrode cartridge keeps your probe running easily and cost effectively. Rely on PHEHT for high-performance pH and ORP monitoring and optimum process control in water treatment.
FAQ pH Sensor
Can the PHEHT probe be used for portable as well as online applications?
Absolutely. Engineered for handheld and in situ use, the pH/ORP probe excels in challenging conditions, offering quick response, minimal flow dependence, and low power consumption.
How to maintain and clean the PHEHT sensor?
Cleansing is performed by immersing the electrode in a special cleaning solution. The electrode must be kept clean, and the calibration checked regularly and adjusted over time. When the electrolyte is depleted (typically in 12 to 18 months), simply swap the replaceable cartridge with a new one and you are good to go!
Is the PHEHT probe compatible with third party devices?
Yes, the probe uses the open and universal Modbus RS485 protocol, allowing easy connectivity with a range of devices, including dataloggers, controllers, PLCs, and remote systems.
