Introduction
A pH/ORP meter is an instrument used to measure the pH and the oxidation-reduction potential (ORP) of the solutions, and it is used in the laboratories, the water treatment, the environmental monitoring, the aquaculture, and the many other applications. The pH/ORP meter measures the pH by the measurement of the potential difference between the pH electrode and the reference electrode, and it measures the ORP by the measurement of the potential difference between the ORP electrode and the reference electrode, and it provides the pH value and the ORP value in millivolts, with the temperature compensation; the pH/ORP meter consists of a meter with the display, the pH and the ORP electrodes, a temperature sensor, and the controls, and it provides features such as the calibration and the automatic temperature compensation; the pH/ORP meter is used for the measurement of the pH and the ORP of the water, the wastewater, the process solutions, the pools, and the aquaculture water, for the quality control, for the monitoring, for the disinfection control, and for many other applications, and it is available as the benchtop and the portable instruments; the pH/ORP meter is an essential instrument for the water analysis. pH/ORP meters are used in the laboratories, in the water treatment, in the environmental monitoring, in the aquaculture, and for many other applications. With their pH and the ORP measurement, pH/ORP meters are essential for the water quality monitoring.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The pH/ORP meter is used in water treatment plants, chemical processing, environmental monitoring, pharmaceutical manufacturing, food and beverage production and research laboratories to measure both pH and oxidation-reduction potential of aqueous solutions. It supports process control in water treatment, chemical reaction monitoring, environmental water quality assessment, fermentation process control and laboratory analysis. The dual capability allows users to assess both acid-base balance and oxidative or reductive capacity with a single instrument, which is particularly useful for water treatment processes where both pH and ORP affect disinfection effectiveness, coagulation and corrosion control. It is essential for facilities requiring comprehensive water chemistry monitoring and process optimization.
Q2: What standards does the meter comply with?
A: The meter complies with ISO 10523 for water quality pH determination, ISO 15839 for water quality sensor performance, relevant GB/T standards, and IEC 61010 laboratory safety standards. Calibration should use certified pH buffer and ORP reference solutions traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole meter is covered by a 12-month warranty. The meter unit and electrodes are covered, while calibration solutions and batteries are consumables excluded from warranty. Electrode damage from improper storage, drying or corrosive samples is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in pH and ORP measurement, electrode calibration and maintenance. We provide an operation manual and remote guidance. Proper electrode handling, calibration procedures and sample preparation are important for accurate results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: pH calibration with certified buffer solutions should be performed before each use session for critical measurements. ORP calibration with reference solution should be performed periodically. Full meter calibration is recommended every 6-12 months. Electrode condition should be monitored and cleaning or regeneration performed when readings become sluggish.
Q7: Are supporting consumables universal?
A: Calibration solutions, storage solutions and electrode filling solutions are available from chemical suppliers, though certified standards are recommended for accuracy. Electrodes may be model-specific and should be sourced from the manufacturer or authorized distributor.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, electrode type, temperature compensation and data output. Additional electrodes, probes and calibration solutions can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No complex installation is required beyond electrode connection and power. The package includes the meter, electrodes, calibration solutions and instruction manual. On-site calibration and training service are available at additional cost.
Q10: What types of samples are compatible with this equipment?
A: The meter measures pH and ORP of aqueous solutions within the measurement ranges and temperature specifications. Highly corrosive samples may damage electrodes and require special material selection. Very low ionic strength samples may require special electrodes and techniques. Users should select appropriate electrodes for the sample matrix, follow proper calibration and storage procedures, and ensure adequate electrode conditioning and response time for accurate and stable readings.
