Brand: Erun
Laboratory desktop boiler water quality tester
Model number:ERUN-ST7-5
Parameters: PH, Conductivity, hydrazine, dissolved oxygen
According to the flow mode of water in the evaporation heating surface, it is divided into natural circulation boiler, forced circulation boiler and direct current boiler; both natural circulation boiler and forced circulation boiler have steam drum, referred to as drum boiler, while the water in the direct current boiler does not circulate, and the preheated water directly enters the riser tube for heating and evaporation. Therefore, the requirements for boiler water testing in the furnace are very high. The laboratory desktop thermal power plant steam boiler water quality tester ERUN-ST7-5 drum boiler and direct current boiler main steam quality test parameters produced by Erun Environmental Protection are:
1.Fully volatile treated water supply: (drum boiler & DC boiler) PH、 hydrazine
2.Oxygenation for feed water: conductivity, dissolved oxygen、PH
ERUN-ST7-5 laboratory benchtop thermal power plant steam boiler water quality tester technical parameters：
1、Fully volatile treated water supply:
序号 | 测定项目 | 测定范围 | 最大误差 | 测量方法国标依据 |
1 | PH（25℃） | 0-14 | ±0.1 | Electrode method |
2 | hydrazine | 0.01-0.5mg/L | 5%(F.S) | Spectrophotometry |
2、Oxygenation for feed water:
Number | Measurement items | Measuring range | Maximum error | Measurement method national standard basis |
1 | PH | 0-14 | ±0.1 | Electrode method |
2 | conductivity(25℃) | 0.00µs/cm-199.9ms/cm | ±0.1 | Electrode method |
3 | dissolved oxygen | 0.1-10.0mg/L | 0.1±5% | Electrode method |
| 0-20mg/L | ±0.2 | Colorimetry |
It can detect the concentration, absorbance and transmittance of nearly 100 parameters in water quality, and can store, print, query and upload them to the computer.
The measurement wavelength is automatically selected.
The instrument is operated by large screen color touch screen, with friendly operation interface, with the help of operation guide, and explains various functional operations.
In addition to the factory curve up to 250 curves, the user can add 3500 curves, can calibrate the curves, and store into the instrument.
Store 100,000 records (including parameter name, concentration, unit, test time, operator number, etc.).
The instrument measurement method can be a straight line method or a broken line method. The broken line method can measure some parameters with poor linear accuracy.
