Product details
1、 Product Introduction:
The RJY-1A dissolved oxygen tester is suitable for detecting dissolved oxygen concentration in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control the dissolved oxygen in water to meet the specified water quality standards.
2、 Principle:
This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved. When measuring, when the tested water sample is poured into the reagent, the water sample will turn orange yellow. Then place this water sample into a photoelectric colorimetric stand, and the instrument will compare the intensity of orange color to determine the concentration of dissolved oxygen.
Technical parameters:
3、 Characteristics:
Microcomputer, touch sensitive keyboard is easy to use. 2. It can automatically zero and calibrate from 1 to 5 points. 3. High performance lithium battery, can be used continuously for 4 hours after 2 hours of charging, ready to use. 4. This instrument adopts a unique semiconductor emitter (patent application number. 2), which has a light source lifespan several orders of magnitude longer than incandescent lamps (about 350 hours), about tens of thousands of hours&# 160; 5. High resolution. The instrument resolution reaches 0.01mg/L.
4、 Usage:
Turn on the power switch, pour the water sample into the glass sample tank, and use a strong absorbent soft cloth or paper to dry the water stains outside the glass sample tank (do not touch the surface of the glass sample tank directly with your fingers to avoid leaving fingerprints on the surface of the glass sample tank and affecting the test results). Put in three drops of reagent (1) and (2) each, shake well and let it stand for 3-5 minutes, then add three drops of reagent (3) and shake well before placing it in the sample tank seat. Cover the sample tank cover and wait for a few seconds for the displayed number to stabilize before reading.
