Instructions for use
Disinfectant baths should be regularly tested. Please follow manufacturer's guidelines. In case of visible contamination, the bath should be renewed.
1. Take only the number of strips required: one test strip for one bath. Tightly close the box immediately after. Avoid touching the test zone.
2. Immerse the strip for 1 second into the bath.
3. Shake the strip to remove excess liquid.
4. Observe, exactly 10 seconds after, the color of the test zone.
Test results:
PASS: If the test zone is completely black, the peracetic acid concentration is higher than 900 ppm. The bath can be kept.
FAIL: If the test zone is colorless or is not completely black (with white spots), the peracetic acid concentration is lower than or equal to 900 ppm. The bath must be renewed.
Important
The test zone coloration begins to change after 10 seconds. Ignore any color change after this time.
Product data
Package with 50 test strips
Test strips dimensions: 5.5 x 95 mm
Special advice
Safety: The cap of the test strips tube contains a non-toxic drying agent. In case of ingestion, drink plenty of water.
Compatibility: If the sample solution has a pH value of 4-6, the reaction will take place without interferences. Acidic solutions must be buffered with sodium acetate, and alkaline solutions with diluted acetic acid to a pH of 5.The following ions interfere with the determination when the concentrations below are exceeded (tested with 0 and 200 mg/L respectively of peracetic acid solutions):
Bound chlorine (chloroamine): 5 mg/L
Fe2+: 5 mg/L
Free chlorine (hypochlorite): 10 mg/L
Ascorbic acid: 15 mg/L
Fe3+:15mg/L
Sulphite (SO32-): 75 mg/L
Formaldehyde: 1000 mg/L
Nitrate (NO3-): 1000 mg/L
Hydrogen peroxide (H2O2): 1000 mg/L
30°d: total hardness
Combining several of these ions can lower the respective limit concentrations.
Storage and disposal: Avoid exposing the test strips to sunlight and moisture. Keep container cool and dry. Store container between +4°C and +30°C. Dispose of the test strips
including packaging as household and similar waste. Do not use after the indicated expiry date
