Description

Overview

GAOTek digital handheld meter is the determination of dissolved oxygen in water device, the working principle is oxygen through the diaphragm by the working electrode reduction, resulting in oxygen concentration is proportional to the diffusion current, by measuring this current, the concentration of dissolved oxygen in water. It can be used to measure processes that are used to affect the reaction rate, process efficiency, or the environment, such as aquaculture, biological reactions, environmental testing (lake, creek, ocean), water or wastewater treatment, and wine production.

 

Features

  • Wide screen LCD display, operation reminder function for easy use
  • It can measure dissolved oxygen concentration, dissolved oxygen saturation and temperature.
  • It has automatic temperature compensation. Also, it can conduct zero oxygen, full scale, atmospheric pressure and salinity calibration.
  • It provides power failure protection, auto power off management. Measuring results can be stored, deleted and viewed.
  • Up to 500 sets of measuring data can be stored.
  • It has RS 232 port and can be connected with TP 16 serial printer. If matched with specific data collecting software, it can be connected to a PC.
  • The protection level of meter housing can reach IP65. Also, it is waterproof and dustproof and suitable for fieldwork.
  • It is equipped with DO 958 S dissolved oxygen sensor.
