Panel-mount Type Dissolved Oxygen Meter (Four-Wire Transmission, Membrane Type)
The HD-480 industrial dissolved oxygen meter takes sequential measurements of the concentration of dissolved oxygen, which is an indicator used in the management of activated sludge tanks in waste water processing, and the quality of the water in boilers, or rivers and waterways.
As there is no need to exchange the membrane of the disposable sensor included, it is easy for anyone to use.
Dissolived oxygen: 0 - 20 mg/L
Saturation: 0 - 200 %
Temperature: 0 - 40 ℃
