OCT-3 PRO Ozone Concentration Tester Do you want to know if you can safely provide a room to clients that has just been ozonated? Or maybe you want to compare the efficiency of ozone generators? The OCT-3 PRO tester is the solution for you. The OCT-3 PRO is effective in assessing the ozone (O3) concentration indoors, allowing you to check if the level is already sufficiently low. It is important to remember that ozone concentration cannot be assessed by smell – the characteristic smell can linger in the room for up to 3 days! However, this does not indicate the presence of ozone. On the other hand, providing access to a room where too much ozone remains is dangerous for those inside. Therefore, after each ozonation, it is worth ensuring that a safe ozone concentration has been achieved. A probe for measuring concentrations from 0-20 ppm is intended for this type of measurement. The tester indicates whether the given value is within the norm (NDS) or if the norm has been exceeded. If you want to assess the efficiency of your ozone generators, use the probe for measuring high concentrations from 10 – 1000 ppm. This is particularly useful when ozonation is performed regularly, and you want to ensure that your generator is still efficient enough to produce a concentration for effective disinfection. The device is intended for assessing ozone (O3) concentration indoors. Depending on the measurement probe used, ozone concentrations can be measured over a wide range. This allows the device to be used for controlling concentration after ozonation or, for example, comparing the efficiency of ozone generators.
