Introduction:
HK-1309DC degassing conductivity analyzer adopts the heating boiling method to effectively remove CO2 in the water and conduct the conductivity measurement to obtain the true water quality hydrogen conductivity value. At the same time, it has a calculation pH unit and measures the ammonia matrix pure water. The specific conductance and positive conductance are used to calculate the pH. The working principle is in accordance with the German VGB-R 450 guideline. It can solve the problem of pH measurement in pure water and effectively avoid the disadvantages of pH electrode measurement. The following indicators can be measured:
1) Measuring the specific conductance and hydrogen conductivity of the sample water.
2) Calculate the sample pH, ammonia content, and CO2 content.
3) Measure sample water flow and monitor resin usage, and promptly replace resin.
4) Heat degassing (CO2) of the sample water passing through the column and measure its degassing hydrogen conductivity.
It is used for water quality monitoring in thermal power steam circulation systems (condensed water, deaerator inlet feed water, economizer inlet feed water, boiler water, saturated steam, superheated steam, and hot net heater drain).
Features:
1. A multi-table, can simultaneously monitor the sample water than the guide, hydrogen conductivity, calculated pH, ammonia content, flow, degassing hydrogen conductivity and other parameters.
2. Panel mounting (stainless steel mounting panel).
3. The calculated pH is based on the German VGB guidelines and is superior to the traditional pH glass electrode.
4. With flow control valve and electronic flow meter.
5. Use a transparent plastic bottle as an ion exchange column for easy replacement.
6. The resin failure alarm function prompts the user to replace the resin in time.
7. Precise boiling point control technology ensures that CO2 removal in sample water is not affected by flow changes.
8. Self-cooling system saves energy.
9. Heat sample off, over-temperature protection function.
10. Patented ultrapure water high temperature compensation technology.
11. The user can customize the parameter display of the main interface.
12. Two-way configurable multiple mode isolated current output function supports up to 800Ω load.
13. The alarm delay function can be set to reduce the malfunction caused by on-site interference.
14. You can use SD card to upgrade the site or retrieve data.
15. Large-capacity file system for large-capacity historical data storage.
16. Four-way relay output, which can be individually configured as alarm output for high and low alarms.
17. The databus of the standard Modbus protocol of the RS485 interface is isolated to realize the digital fieldbus technology.
