Description
Apera SX716 is designed for lab-grade DO measurement (dissolved oxygen) in the field, suitable for general water solutions’ applications such as water treatment, groundwater, surface water, environmental monitoring, aquaculture, aquarium, beverage making, etc.
Features:
- Comes with Apera's proprietary polarographic DO electrode with a calibration sleeve replaceable membrane cap, and built-in salinity and temperature sensors
- Easy calibration for saturated oxygen and zero oxygen
- Auto. compensation for temperature and salinity, manual compensation for barometric pressure (altitude)
- Data logging and recalling function with 400 sets of data storage
- IP57 water resistant, all accessories in a rugged carrying case
- Intelligent functions –– auto. calibration, auto. temperature compensation, self-diagnosis, data logging, auto. power off, and more.
- Digital filter technology –– enhance the meter’s response time and measurement accuracy
- Automatic electrode recognition –– the meter automatically switches to the right parameter mode according to the connected electrode
