PGF- II silicate analyzerDetailed product description：

The PGF-II digital silicate analyzer is a laboratory instrument widely used to determine the content of silicate ions (SiO2) in boiler feedwater steam, chemical desalinated water, condensate water, and pure water in the semiconductor device industry, chemical plants, pharmaceutical plants, etc. It can meet the needs of different users

Introduction to PGF-II Silicate Analyzer
The PGF-II digital silicate analyzer is an instrument that can measure trace elements in water. Its highly reliable circuit design provides you with the most reliable data; Featuring a three and a half digit LED digital display, LED and LCD displays make data observation more intuitive and convenient; Optional for precise measurements in the laboratory.
1. Measurement range: 0-199.9ug/L SiO2.
2. Accuracy: Basic error: ± 2.5% (basic error is ± 2ug/L for 0-50ug/L SiO2) Repeatability:<± 1 (full scale) Stability: Drift per hour<± 0.5% (full scale)
3. Power supply: Supply voltage: Ac220V ± 10%; 50HZ power consumption: 30W
4. Dimensions: 360mm x 310mm x 160mm (width x depth x height)
5. Transportation conditions: There are glass products inside the instrument, and special attention must be paid to shock and moisture prevention during transportation and storage. Do not invert.
6. Storage conditions: Room temperature: 0-40 ℃. Indoor environment with relative humidity not exceeding 85% and no corrosive gases.
7. Working conditions: Environmental temperature:+15 ℃ -+40 ℃ Relative humidity: not greater than 85% RH Tested water sample temperature:+20 ℃ -+40 ℃
8. Allowable content of interfering ions in the tested water sample: Na+<500ug/L， Mg++<200ug/L， Zn++<200ug/L， Fe+++<100ug/L， Ca++<200ug/L，Cu++<200ug/L， Al+++<150ug/L， Fe++<200 ug/L
9. Precautions
Measurements can be taken 10 minutes after turning on the device.
2. During use, calibrate the upper and lower indexes of each batch of samples before testing.
3. The instrument should be placed horizontally, avoiding direct sunlight, without strong convective gases, strong electromagnetic interference around it, no vibration that affects use, and no corrosive gases.
4. It is recommended to inject the tested water sample twice for each measurement, and the second displayed value shall prevail.
5. The drainage time should not be too long each time. After draining the water sample, immediately press the valve switch to restore it to the sample delivery state.
After each measurement is completed, high-purity water should be injected and not discharged.
After long-term use, the colorimetric dish should be removed and washed with 5% hydrochloric acid solution, paying attention to the cleanliness of both ends of the colorimetric dish.
The light source bulb is a vulnerable component. When users replace the bulb, do not loosen or move the socket that holds the bulb in place. Otherwise, recalibrate the instrument and determine a new set of upper and lower index values. 9. To ensure the stability and good heat dissipation performance of the instrument, the top cover of the chassis should be opened before use.
