FAQ
Q1: What testing scenarios is this tester mainly applied to?
A: The acid and alkali tester is used in chemical manufacturing, food and beverage production, pharmaceutical quality control, water treatment, environmental monitoring and agricultural testing to measure the acidity or alkalinity of solutions, products and samples. It supports pH measurement for chemical process control, food and beverage quality assessment, pharmaceutical formulation testing, water and wastewater treatment monitoring, soil and agricultural analysis, and environmental water quality assessment. The tester provides a direct indication of acid-base balance, which is critical for product quality, process optimization, corrosion control and regulatory compliance. It is essential for laboratories and production facilities requiring reliable pH measurement for quality control, process monitoring, environmental compliance and product development, where acid-base properties affect chemical reactions, product stability, taste, safety and environmental impact across multiple industries.
Q2: What standards does the tester comply with?
A: The pH meter complies with ISO 10523 for water quality pH determination, relevant GB/T standards, and IEC 61010 laboratory safety standards. Calibration should use certified pH buffer solutions traceable to international standards. Food and pharmaceutical applications follow applicable pharmacopoeial and industry standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The meter unit and electrode 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 measurement, electrode calibration and maintenance. We provide an operation manual and remote guidance. Proper electrode calibration, storage and sample handling are important for accurate pH 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: Calibration with certified pH buffers should be performed before each use session for critical measurements. Full meter calibration recommended every 6-12 months. Electrode condition monitored and cleaning or regeneration performed when readings become sluggish. Storage solution level maintained for refillable electrodes.
Q7: Are supporting consumables universal?
A: Calibration buffers, 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, electrode, 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 tester measures pH of aqueous solutions within the measurement range and temperature specification. Highly corrosive samples may damage electrodes and require special material selection. Very low ionic strength samples require special electrodes and techniques. Non-aqueous samples require appropriate electrodes and calibration. Users should select appropriate electrodes for the sample matrix, follow proper calibration and storage procedures, ensure adequate electrode response time, and clean electrodes between measurements to prevent cross-contamination and maintain accuracy.
