I. Product Purpose
The DDKSCI Benchtop pH DO Meter is a multi-parameter benchtop testing instrument specially designed for laboratories and fixed locations. Its core function is to simultaneously and accurately measure the pH value, mV value (with an optional ORP probe), and dissolved oxygen (DO) content of liquids.
It covers multiple fields including scientific research, industrial production, environmental monitoring, food processing, and pharmaceuticals.It can obtain a variety of key water quality parameters in one go, meeting the high-frequency, multi-indicator testing needs of fixed sites without the need to configure multiple single-parameter testers.
II.Key Technical Specifications
pH Measurement: Range of -2.00–20.00pH, resolution of 0.01/0.1pH, and accuracy of ±0.01pH±1 digit.
DO Measurement: Range of 0–20.00mg/L, accuracy of ±0.30mg/L, and resolution of 0.01/0.1mg/L.mV Measurement: Range of -1999mV to +1999mV, with an accuracy of ±0.1%FS±1 digit.
Temperature Measurement: Range of -9.9–130.0℃, accuracy of ±0.2℃, and supports manual salinity compensation of 0–45ppt.
Data Management: It can store 450 sets of data with measurement timestamps for easy traceability; it is equipped with a USB interface for exporting data to a U disk and supports wireless connection to printers (printer optional).
III.Core Advantages
This Benchtop pH DO Meter boasts numerous standout features:
Smart Automatic Calibration
It has a high-performance built-in microprocessor chip. It supports smart automatic calibration: pH allows 1–3 point calibration and can automatically recognize standard buffer solutions; DO supports 100% oxygen or zero-oxygen calibration. It also has automatic temperature compensation. You do not need to do repeated manual adjustments, so operation is simple and data is accurate.
Clear & Stable Display
Its high-resolution LCD screen shows readings clearly and easily to understand. It has fast response speed. Test results display stably after measurement, so you won’t misread data.
Reliable Durability
It has an IP54 protection level, so it is dustproof and splash-proof. It won’t get damaged from accidental liquid splashes in the lab.
Each set comes with a 3-in-1 pH probe, polarographic DO probe, and 3 replaceable sensor membrane caps. It can be assembled and used immediately upon receipt, with convenient maintenance.
IV. Application Scenarios
Food Processing Factories: The Benchtop pH DO Meter can simultaneously detect the pH value and DO content of raw material liquids, completing two indicators in one operation to improve quality inspection efficiency.
Environmental Protection Laboratories: When conducting batch testing of sewage, it can synchronously obtain pH and DO data to support pollution analysis.Pharmaceutical Enterprises: It monitors multi-parameter indicators of production water to ensure water quality meets standards.
Scientific Research Institutions: Its precise multi-parameter data provides reliable support for water quality experiments.
V. Complete Packaging
