PHS-3C digital pH meter measuring 0–14 pH and 0–1999 mV with combination glass electrode for water and solution analysis.
Overview
The PHS-3C digital PHS-3C Digital pH Meter measures solution pH and electromotive mV values; parameters and measurement are switched by keys and shown on an LED display. It uses a full-range room-temperature combined glass electrode and measures 014pH and 01999mV at 0.1% full-scale accuracy, with LED readout and simultaneous temperature compensation. It is accurate, reliable and easy to operate, an ideal instrument for laboratory use.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Microcomputer-controlled operation with digital display for direct readout
• High measurement accuracy with stable repeatability
• Large LCD display showing real-time test parameters and results
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the PHS-3C Digital pH Meter comply with?
A1: The PHS-3C Digital pH Meter is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the PHS-3C Digital pH Meter be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
