91336 QUANTOFIX LubriCheck test strips

Creation of the template:

A simple reading template should be created before routine use. The instructions can of course be adapted.

• One camera (mobile phone is sufficient)
• A white sheet of paper. Write the following on the paper: Cooling lubricant, under each strip the corresponding concentration, (see below)
• 5 beakers, 1 measuring cylinder 100 ml
• water, concentrate
• 1 disposable syringe 10 ml (to measure the concentrate)
• Prepare a beaker at the maximum expected concentration, e.g. nominal concentration = 5% ... 2xCnominal = Cmax 10%.

Dilute this solution in 4 additional beakers:

1. Glass: One volume part with Cmax + 3 volume of water = C1
   (50%target concentration, here 2.5 %)
2. Glass: One volume part with Cmax + 2 volume of water = C2
   (66% nominal concentration, here 3.3%)
3. Glass: One volume part with Cmax +1 volume of water = C3 (nominal concentration, here 5%)
4. Glass: 2 volume parts with Cmax +1 volume of water = C4 (133% of nominal concentration, here 6.7%)
5. Glass: One volume part with Cmax undiluted, here 10%

• Remove 5 individual sticks and briefly dip each into beaker 1,2,3,4,5
• on the sheet in the right place!
• photograph directly on a white background next to each other.

Shrink-wrap the printed image and hang it on the machine.

If the alkalinity in the nominal concentration already causes all fields to change over, a sample must be diluted (e.g. 1:1) before the measurement. Of course, this has to be done in the same way when creating the template and during the routine measurement.
