SLDW1120 Series pH Meter: A Practical Choice for Water Quality Monitoring in Foreign Trade Scenarios
In transnational industrial fields such as chemical engineering, water treatment, and food processing, the stable monitoring of pH value and ORP value is a fundamental link to ensure production processes and product quality. With its performance and adaptability that meet practical needs, the SLDW1120 Series pH Meter provides support for water quality monitoring scenarios involved in foreign trade business and becomes a practical tool for enterprises to serve international customers.

Accurate and Stable, Meeting Basic Monitoring Requirements
As a measuring instrument, accuracy is a core requirement. The pH measurement range of the SLDW1120 Series pH Meter covers 0~14pH with an accuracy of 0.1pH; the ORP measurement range is -2000~2000mV, with an error controlled within ±1mV. At the same time, the temperature detection accuracy is ±0.1°C, which can meet the basic requirements for the accuracy of monitoring data in industrial scenarios.
Durable and Adaptable, Coping with Diverse Usage Environments
The product focuses on practicality in material selection and protection design: the transmitter is made of ABS+PC material, and the sensor combines plastic and glass technology, balancing corrosion resistance and structural stability; the transmitter has an IP65 protection level, and the sensor reaches IP68. Combined with the maximum working pressure resistance of 4bar, it can adapt to the usage needs of different environments such as laboratories and industrial sites. In terms of power supply, it supports two modes: AC 85-265VAC (50/60Hz) and DC 24VDC±10%, which is convenient for dealing with power supply scenarios in different regions and reduces the adaptation and adjustment links during foreign trade export.
Convenient and Easy to Maintain, Lowering the Threshold for Use
The instrument has a built-in microcomputer circuit, supporting sample calibration and factory calibration. No calibration is required within one year after leaving the factory, which reduces the frequency of daily maintenance; the LCD screen can clearly display information such as measured values, time, and instrument status. On-site settings can be completed through the transmitter buttons, and the operation logic is simple and easy to understand. In addition, it is equipped with automatic storage and power-off data protection functions to avoid the loss of measurement data; 2 channels of isolated 4~20mA analog output and 3 configurable relay outputs can be flexibly connected to the control system, and can also realize the automatic cleaning timing function, further improving the convenience of use.
With its performance that meets practical needs, durable design, and convenient operation, the SLDW1120 Series pH Meter provides reliable support for water quality monitoring in foreign trade scenarios and is a practical choice for enterprises when serving international customers.
