PHS-3CT microcomputer pH meter with automatic two-point calibration, temperature compensation and pH/mV/temperature display.
Overview
The PHS-3CT PHS-3CT Microcomputer pH Meter uses the latest microprocessor technology. It features automatic slope calibration with two-point pH7/pH4 recognition and beep reminder; manual/auto temperature compensation; dual pH/mV/temperature display; software-calculated results with no adjustable parts; automatic parameter storage retained after power-off; automatic electrode slope and deviation display. It uses the factory E-201 combined electrode with temperature probe and can connect to a PC (software optional).
Applications

FAQ
Q1: What standards does the PHS-3CT Microcomputer pH Meter comply with?
A1: The PHS-3CT Microcomputer 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-3CT Microcomputer 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.
