Ensuring you know how much dissolved oxygen is in your water!

Knowing how much dissolved oxygen you have in your water can help decide when you need your aeration on, a good quality meter takes all the guess work out of this.

The dissolved Oxygen Meter AZ-8403 features high performance and accuracy with large LCD to display dissolved oxygen and temperature value display.

It has clear ready indicator prompts whenever reading stabilises. LCD display shows measured DO displayed in % or in ppm/mg/l and Barometric are displayed in mmHg or KPA, Temperature in C, Salinity in ppt.

Features include 99 memory data with temperature readings, auto-power off by selecting time frame, Max / Min / AVG function help to analyse the data.
