The Hanna HI9147-04 is a rugged, water-resistant dissolved oxygen meter built for aquaculture and demanding field conditions. It measures DO from 0.0 to 50.0 mg/L and 0 to 600% saturation, with a galvanic probe that requires no warm-up or conditioning time — pick it up and measure on demand.

Key features

• Galvanic DO probe (silver cathode / zinc anode) needs no polarization time — ideal for measuring many samples quickly
• Automatic temperature compensation plus manual salinity and altitude compensation for accurate DO in salty or high-elevation water
• Manual one-point calibration; water-resistant housing for field durability
• Supplied with a 4 m (13') probe cable for cages, tanks, and ponds
