The determination of nitrite and pH is essential for assessing the properties of cooling lubricants. A nitrite concentration of up to 80 mg/L and a pH range of 6.0-9.6 can be easily measured with our QUANTOFIX Nitrite / pH combination test strip.
With our new product QUANTOFIX Nitrite / pH 2 it is even possible to analyse nitrite concentrations up to 100 mg/L. The pH range is optimised for the requirements of coolant analysis and covers pH 8-10 in a particularly fine gradation. This makes coolant analysis just as easy, but even more accurate!
Nitrite gradation: 0 · 1 · 5 · 10 · 20 · 40 · 80 · 100 mg/L NO₂⁻
pH gradation: 8.0 · 8.2 · 8.4 · 8.6 · 8.8 · 9.0 · 9.2 · 9.4 · 9.6 · 9.8 · 10.0
