Overview
The DWS-51 sodium ion concentration meter is a professional instrument of QIWEI brand for the measurement of sodium ion content in aqueous solutions. The instrument is especially suitable for mass monitoring of high-purity water (such as steam, water, boiler feed water, etc.) in power plants, and can also be used in universities, scientific research departments, Petrochemicals, microelectronics and other fields to determine the concentration or activity of sodium ions in natural water and industrial drainage.
Features
1. Measurement range: PNA value 0~ 9, Na + concentration 0.23 nm g/L~ 23 g/L, mV Measurement range -1800~ 1800mV.
2. High Accuracy: resolution 0.01 PNA, electronic unit intrinsic error +/- 0.02pNa +/- 1 word, instrument intrinsic error +/- 0.05PNA.
3. Repeatability: Instrument repeatability error does not exceed 0.03pNa +/- 1 word.
4 temperature compensation: temperature compensation range of 5~ 50 ℃.
5. Strong environmental adaptability: Ambient Temperature 5~ 40 ℃, Operating Relative Humidity does not exceed 80%.
6. Power supply stability: AC 220V +/- 22V, Frequency 50 +/- 1 Hz.
7. Lightweight design: weight only 1.5KG.
Principle
Based on electrochemistry principles, the instrument quantitatively analyzes the concentration or activity of sodium ions by measuring the potential difference (mV value) generated by sodium ions in aqueous solutions, combined with temperature compensation to ensure measurement accuracy.
Applications
Power plant high-purity water monitoring, universities, scientific research departments, Petrochemicals, microelectronics, natural water measurement, industrial drainage analysis
Steps
1. Connect power supply: AC 220V +/- 22V power supply, Frequency 50 +/- 1 Hz.
2. Environment inspection: Ensure that the working Ambient Temperature is 5~ 40 ℃, and the relative humidity does not exceed 80%.
3. Instrument calibrating: calibrate according to the instructions to ensure that the electronic unit and instrument errors are within the allowable range.
4. Sample measurement: Place the sample in the instrument and read the PNA value or mV value.
5. Data logging: Record sodium ion concentration or activity data.
6. Cleaning and maintenance: Clean the instrument after use and keep it drying.
Notice
• Ambient Temperature should be controlled within the range of 5~ 40 ℃.
• The relative humidity should not exceed 80%.
• Power supply voltage needs to be stable at 220V +/- 22V, Frequency 50 +/- 1 Hz.
• Avoid Violent Vibration or Impact of the Instrument.
• Periodically calibrate instruments to ensure Measurement accuracy.
• Clean and dry the instrument immediately after use.
