Trans Instruments WalkLAB Digital Dissolved Oxygen Meter HD9031/HD9031N
The WalkLAB Dissolved Oxygen Meter HD9031 is designed for full portability. This economical meter is most suitable for use at sea level and for fresh water. The HD9031 comes with a standard 3-meter probe. And the HD9031N comes with 1-meter probe. Each unit comes with an extra membrane, a bottle electrolyte. This basic DO meter is most popular for schools or lab user and the probe size is suitable for BOD bottle testing. For aquaculture users it is simple to use, the single session Salinity and atmospheric pressure setup will automatically compensates DO reading for the session.
Advanced Features:
- Large and easy to read Liquid Crystal Display.
- Fast in-air calibration provides accurate calibration without complicated procedures.
- Low battery indicator provides early warning of weak batteries.
- Session set atmospheric and salinity compensation
- Uses durable long-lasting components including a weather resistant splash proof plastic casing.
