Overview
PXS-NO3 nitrate ion meter is a QIWEI brand instrument designed for the measurement of nitrate ion content in aqueous solutions. This instrument is suitable for universities, scientific research institutions, Petrochemicals, microelectronics and other departments to determine nitrate Ion concentration (or activity) in natural water, laboratory water, industrial drainage and other water.
Features
1. Adopting single-chip microcomputer technology, the operation is simple and convenient, and the digital display is intuitive and correct.
2. With manual temperature compensation and automatic temperature compensation functions, automatic temperature compensation needs to be connected to temperature Electrode (optional accessories).
3. In addition to displaying the pNO3 value, it also has the function of displaying the nitrate Ion concentration value [NO3] and the corresponding Ion concentration potential function.
4. The instrument is beautiful and lightweight in appearance.
Principle
By measuring the nitrate Ion concentration (or activity) in aqueous solution, the instrument processes the data using microcontroller technology to realize the display of pNO3 value, Ion concentration value and potential value, and supports the function of temperature compensation to improve the measurement accuracy.
Applications
Colleges and universities, scientific research institutions, Petrochemicals, microelectronics, natural water testing, laboratory water testing, industrial drainage testing
Steps
1. Connect the power supply (AC 220V +/- 22V, Frequency 50 +/- 1 Hz).
2. Connect temperature Electrode as needed to enable automatic temperature compensation, or set manual temperature compensation.
3. Immerse the instrument Probe into the tested aqueous solution.
4. Read and record the pNO3 value, nitrate Ion concentration value or potential value.
Notice
• Temperature Electrode is an optional accessory, and users need to ask when ordering if they need to use it.
• The working ambient temperature range is 5~ 40 ℃, and the relative humidity does not exceed 80%.
• The intrinsic error of the instrument is +/- 0.05pNO3, and the error range should be paid attention to when using it.
• Power supply voltage in AC 220V +/- 22V range, Frequency of 50 +/- 1 Hz.
• Instrument weight is 1.5kg, Dimension is 230 * 190 * 80mm, handling with care.
