Гидротермометр Analox

When using the Analox ATA pro you should first calibrate the unit as per the instructions, with the O2 reading being at 20.9% (or the more precise figure from the table provided with the hygrothermometer), then zero the helium figure. If using a twinset, ensure that the manifold is open, then establish a gentle flow (GUE recommends using the right post for multiple reasons) before offering the flow restrictor up to the tank valve. Let the readout settle and then mark this directly on the tank, on a piece of regular or gas analysis tape, making sure to use decimal places. Most technical agencies will recommend analysing on the day of the dive, and to re-analyse again if there is any doubt what so ever as to the contents and if they may have been interfered with or altered.
