What is the price of instruments for analyzing and measuring water quality affected by environmental pollution? Urgent! ! !
What do you want to measure? COD, SS? Or trace elements?
If you have conducted your own research, you can use the following test strips: Test Strip Name, Model, Origin, Detection Range, Unit Price (yuan per box). Test strip for sulfides in water: 211LL, Japan; Detection range: 0.5–20 ppm; Price: 208.00. Test strip for sulfides in water: 211, Japan; Detection range: 1–100 ppm; Price: 184.00. Test strip for sulfides in water: 211M, Japan; Detection range: 2–300 ppm; Price: 184.00. Test strip for ozone in water: 218, Japan; Detection range: (1)–10 mg/l; Price: 208.00. Test strip for chloride ions in water: 221L, Japan; Detection range: (25)–1000 mg/l; Price: 184.00. Test strip for chloride ions in water: 221LL, Japan; Detection range: 10–200 mg/l; Price: 184.00. Test strip for free chlorine in water: 222, Japan; Detection range: 0.1–10 mg/l; Price: 208.00. Test strip for mercury in water: 271, Japan; Detection range: 1–20 mg/l; Price: 208.00. Test strip for hexavalent chromium in water: 273, Japan; Detection range: (0.5)–50 mg/l; Price: 208.00. Test strip for ferrous iron in water: 281, Japan; Detection range: (5)–50 mg/l; Price: 208.00. Test strip for copper in water: 284, Japan; Detection range: (1)–20 mg/l; Price: 208.00. Test strip for zinc in water: 285, Japan; Detection range: 3–20 mg/l; Price: 208.00. Test strip for nickel in water: 291, Japan; Detection range: (5)–50 mg/l; Price: 208.00
Apart from sodium ions, other metal ions can generally be determined using an ultraviolet-visible spectrophotometer. If you have the money, go ahead and buy an ICP; but it seems a bit extravagant to use one just to test water quality once.
Thank you all, my thanks come a little late! ! !
