OTZ (One Time Zero)

The One Time Zero is available for all photometer variants whereby the zero adjustment

is carried out in a 24-mm round vial with sample water. It can be used if different tests are

carried out with identical test conditions and the same water sample. The zero adjustment

is saved until the device is switched off.

The zero setting can be repeated each time if necessary
