YR06615 Benchtop pH Meter

The YR06615 pH Meter is a high-precision professional instrument designed for laboratories, industries, universities, and field applications where strict control of pH, ORP (mV), and temperature is required. It features a large, intuitive, full-color touchscreen that allows direct measurements, efficient data entry, and user management in accordance with GLP (Good Laboratory Practice) standards. Its wide measurement range from −2.000 to 20.000 pH, with an accuracy of ±0.002 pH, makes it a reliable solution for demanding analyses. In addition, the instrument can store up to 2,000 data sets, including timestamp, sample, and sensor ID, with automatic USB export, ensuring full traceability and secure data backup. In the market, the YR06615 pH Meter is positioned as a competitive alternative to high-end brands, offering advanced features at an optimized cost. This makes it ideal for both established laboratories and projects seeking excellent value for money. Its compact design, IP54 protection, and compatibility with automatic or manual temperature compensation ensure stable results even under variable environmental conditions.

Frequently Asked Questions

One of the most common questions is whether the instrument supports advanced calibration: the YR06615 allows automatic calibration from 1 to 5 points, compatible with international standards, ensuring consistent accuracy. Another frequent question is whether it can be used for ORP and temperature measurements; the answer is yes—it measures ORP up to ±2000 mV and temperature from −30 °C to 130 °C, all integrated into a single instrument. Data export is also a common concern; thanks to its USB output, records can be easily transferred for reports or audits.

Advantages and Disadvantages

Among its main advantages are its high accuracy, full-color touchscreen, GLP-compliant user management, and large internal storage capacity. Its stability of ±0.01 pH over 3 hours makes it ideal for long-term measurements. As a possible drawback, since it is an advanced instrument, a brief initial training is recommended to fully take advantage of all its functions, especially in environments previously using basic meters.

Field Use

The YR06615 pH Meter is widely used in industrial quality control, water analysis, chemical, pharmaceutical, and food laboratories, as well as in academic research. In the field, its robust design and IP54 protection allow reliable measurements in treatment plants, production processes, or environmental inspections, bringing laboratory-level accuracy directly to the work site.

Recommendations

To maximize performance, periodic calibration with certified buffer solutions is recommended, along with keeping the electrodes clean and storing the instrument properly after each use. Taking advantage of the data storage and export functions facilitates historical tracking of measurements and improves quality management.
