Suggestions for choosing a dissolved oxygen meter with a DO sensor suitable for each industry

Aquaculture - Deciding on the Risk of Hypoxia Causing Fish Kills

In the aquaculture industry, dissolved oxygen meters will directly determine the growth and survival rate of aquatic animals; even a 1 ppm drop can cause great damage, so you need a durable, salinity-compensated and low-maintenance device. A machine with an optical DO sensor, Optical minimizes calibration time, reduces the workload and ensures stable data. 

Some suitable handheld optical meters: EZDO 7031 Handheld DO/O2/Temperature Meter (Waterproof), REX DO210E handheld DO meter

Environmental science

In environments such as lakes, rivers, and streams with constantly changing natural conditions, researchers and scientists need multi-parameter, data logger, GPS, long and durable probes. 

The ideal device would be a handheld multi-parameter meter, with a DO sensor suitable for monitoring pH, conductivity, and turbidity in a variety of water bodies.

Suggested suitable measuring device: HANNA HI9146-10 Dissolved Oxygen Meter

SMARTSENSOR AR8210 Dissolved Oxygen Meter

Wastewater treatment plant operation 

For aerobic tanks, a durable, dirt-resistant, and easily calibrated DO sensor provides precise system control and reduces operating costs. The ideal instrument for this industry would be a combination of a handheld device and a continuous measurement system.

Used for laboratory research work

In cell research, primary productivity or microbiological applications, very low DO levels are of great significance. The demands of DO sensors in this industry include maximum accuracy, advanced analysis software, and specialized probes for small volumes. The ideal instrument to suit the expertise would be a laboratory-grade benchtop.

Hydroponic Gardening & Basic Water Testing

Hydroponics players or technicians only need simple equipment to quickly check the oxygen level in the water, so devices with easy operation, fast DO sensor measurement, and reasonable cost will be extremely suitable.

You can refer to single-function measuring pens or handheld devices such as the DO measuring pen EXTECH DO600

To achieve optimal accuracy and efficiency, you need to match your real-world needs with the right technology. From field-based optical devices to dedicated benchtop units, choosing the right DO sensor will help you control consistent water quality.
