HD-480
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.
Measuring range
Dissolived oxygen: 0 - 20 mg/L
Saturation: 0 - 200 %
Temperature: 0 - 40 ℃
Segment: Process And Environmental
Division: Process Water
Fabricant: HORIBA Advanced Techno Co., Ltd.
- Exchanging the sensor is a one-touch operation
The sensor is disposable, and can be exchanged with the touch of a key.
There is no need for work requiring long experience or expertise, such as exchanging the membrane or refilling the internal fluid, as generally required by other sensors until now. - Two types of span correction
You can choose from two types of span correction: the commonly used saturated fluid correction, and the plain and simple atmospheric correction. - Salt adjustment function
A function which automatically corrects the data based on the salt concentration of the measurement sample has been included.
This means it can make precise measurements in both freshwater and seawater. - Uses lead-free solder
To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
