Product Name: German imports of Asian paper 91322 sodium nitrite concentration of cutting fluid rapid detection ratio of 0.3% brief: Germany imported nitrite test strips, rapid detection of nitrite is the best solution. 1-minute simple test can be obtained reliable test results. Scope: MN nitrite test strips are widely used in environmental monitoring, waste water treatment and other industries. MN nitrite test strip (91,322) is also applied to metal coolant, cutting fluids, cooling lubricants detection. Specific parameters: Product name nitrite test strips (high concentration) type semi-quantitative test strips boxed product specifications, 100 / box color reaction yellow - red Origin Germany unit scale 0-0.1-0.3-0.6-1-2-3 g / l NO 2- 0-100-300-600-1000-2000-3000 mg / l (Note: 3000 mg / l = 0.3%) item number 91322 is valid for two years and a half to use: Remove a certain amount of the desired test strip, immediately cover the lid. Do not touch the reaction zone of the test strip. The PH value of the test strip is immersed in a solution of 2-12, remove the test strip 1 second. 60 seconds after the color of the standard reaction zone of the test strip contrast than the color card. The presence of nitrite, the paper turns red-orange reaction zone. Jamming: acid and alkali solution with sodium hydroxide solution were required and sulfuric acid to adjust the PH value to 4-6. The following ion concentrations greater cause jamming:> 1000 mg / l Ag +, Al 3+, Ba 2+, Ca 2+, Cd 2+, Co 2+, Cr 3+, Cu 2+, Hg + / 2 + , K +, Mg 2+, Mn 2+, NH 4+, Na +, Ni 2+, Pb 2+, Sr 2+, TI +, Zn 2+, Acetate, Ci tr ate, Ox al ate, Tar tr ate, ED TA, Br-, CO 32-, Cl-, Cl O 3-, Cl O 4-, NO 3-, PO 43-, SO 32-, SO 42-, S 2 O 52-, Se O 32-> 500 mg / l Bi 3+, Fe 2 + / 3 +, C N-, Cr O 42-, F-, Mn O 4-, S 2 O 32-> 100 mg / l As 3+, Li +, Sn 2+ , As cor bate, S 2-, SC N-, S 2 O 42- Storage: Avoid exposing the test strips sunny and humid environment.
