1、 Product Introduction

The RJY-1 desktop dissolved oxygen analyzer uses the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved. The molecular oxygen in the air dissolved in water is called dissolved oxygen, and the content of dissolved oxygen in water is closely related to the partial pressure of oxygen in the air and the temperature of water. In natural conditions, the oxygen content in the air does not change much, so water temperature is the main factor. The lower the water temperature, the higher the dissolved oxygen content in the water. The molecular oxygen dissolved in water is called dissolved oxygen, usually denoted as DO, expressed in milligrams of oxygen per liter of water. The amount of dissolved oxygen in water is an indicator of the self purification capacity of a water body. The RJY-1 dissolved oxygen tester can be used to detect the concentration of dissolved oxygen in water samplesControl the dissolved oxygen in water to meet the specified water quality standards. Complies with the national standard GB/T5750-2006 for hygiene of drinking water.

3、 Product Features

1. Microcomputer, touch sensitive keyboard, clear display of LCD numbers, easy to use.

2. The photoelectric colorimetric principle of spectrophotometry is adopted, which is convenient for the application of reagents. After the water sample is placed in the reagent for reaction, it can be read within a few minutes, and the digital display shows the value of dissolved oxygen. The reagent is packaged in a convenient drip bottle.

3. Our company's unique technology LED light source automatic control circuit ensures stable light source and solves the problem of preheating during startup. Its light source has a lifespan of up to 20 years and can be used directly without preheating when turned on.

4. The host can be equipped with a high-power lithium battery, which can be used for quantitative measurement in the field. It can be continuously used for 4 hours after 2 hours of charging, and is ready to use.

5. The instrument stores calibration curves within the full range, with power-off protection, and calibration data will not be lost. It can automatically zero and calibrate at 5 points, with non-linear processing and data smoothing functions. The instrument has a minimum reading of 0.01mg/L.

6. Advanced technology, in line with the national standard GB/T5750-2006 for drinking water hygiene.
