Oxygen meterbrief introduction

Oxygen meter is a high-performance portable measuring instrument used to measure the pH ORP、 The parameters such as conductivity, salinity, TDS, etc. have a simple appearance, light weight, integrated circuit, high intelligence, and are easy to understand and operate through human-machine dialogue. They have high measurement accuracy and are particularly suitable for applications in industries such as petrochemicals, power, beverages, pharmaceuticals, semiconductors, and research institutes.

characteristic

1) A wide temperature and high brightness dot matrix LCD display with a large viewing angle, suitable for use in low light and low temperature environments;

2) Simple structure, small size, light weight, easy to carry, and flexible to use;

3) Intelligent human-machine dialogue operation interface, easy to understand and use;

4) Intermittent or continuous data storage, measurement data can be uploaded to a computer for secondary storage and processing;

5) Comes with a built-in USB interface, featuring self charging and data export functions;

6) Key parameter password protection to prevent non operators from accidentally operating the machine and ensure the basic performance of the instrument;

7) It has the function of storing and querying measurement data, operation, and calibration records, and can store 600 pieces of measurement data;

8) Continuous use time shall not be less than 40 hours;
