Extech DO701 syremätare

The Extech DO701 stands out with its automatic salinity and barometric pressure compensation, ensuring accurate dissolved oxygen readings in varying water conditions. This portable meter combines DO and temperature measurement in a rugged IP57-rated housing, making it suitable for field use.

Highlights

• Measures dissolved oxygen from 0.00 to 20.00 mg/L and 0.0 to 200.0% saturation
• Automatic temperature, salinity (0 to 50 ppt), and barometric pressure (500 to 1400 hPa) compensation
• Backlit LCD with 99-reading data memory
• Waterproof IP57 meter housing

In daily use

The DO701 provides reliable dissolved oxygen measurements for water quality testing. Its polarographic electrode and automatic calibration (air or 0% solution) streamline operation. The backlit display ensures readability in low light, and stored readings can be reviewed on the meter.
