Benchtop DO Water Quality Meter with USB/SD Datalogging

Introducing our state-of-the-art Benchtop Dissolved Oxygen Water Quality Meter, the perfect solution for comprehensive water analysis.

This innovative instrument integrates advanced electronics, sensors and software design to accurately measure Dissolved Oxygen (DO) and other parameters, including EC, pH, TDS, temperature and more (with additional probes). Its compact and portable design makes it ideal for use in industrial and mining enterprises, power plants, labs and various environmental applications.

The meter is equipped with a built-in microprocessor, offering automatic calibration, temperature compensation (both manual and automatic), data storage, function settings, automatic shutdown and low voltage alarms. These intelligent features ensure ease of use and reliable performance in various testing conditions. The digital filtering and slip techniques enhance the meter's response speed and data accuracy, providing precise and trustworthy results.

The meter comes with a range of sophisticated features:

  • Elegant, functional design with 5 inch backlit LCD screen and wide 150° viewing angle
  • Compact bench cradle with rotary electrode holder saves space in lab
  • Small size and easy portability
  • Extendibility: Additional electrodes can be installed to test conductivity,  dissolved oxygen and more
  • 3.5 mm jack input for easy electrode connection
  • Two USB and one SD card interfaces for power and data transfer
  • Can store 300 pieces of data internally, including readings, date and time
  • Rechargeable, long lasting battery
  • Auto shut off if there is no operation in ten minutes

Complete DO kit includes:

  • L-512 Dissolved Oxygen Meter
  • DO electrode (ATC) with cap
  • Electrode holder and base
  • Electrolyte
  • Power adapter
  • USB thumb drive with users manual
