Product Description

Factory price for High Accuracy DO Meter Portable Dissolved Oxygen Meter

Basic handheld dissolved oxygen meters can cost around $100 to $300. They have a simple interface and are suitable for applications that require occasional measurements.

More advanced models with additional features, such as data logging, automatic calibration, and digital interfaces, can cost up to $1,000 or more. These models are suitable for applications that require more precise measurements, such as in scientific research or wastewater treatment plants.

Product Description

 
 
The handheld device can be used for monitoring of dissolved oxygen, temperature and PH in water, and can meet the requirements of portable accurate water quality measurement.
Signal output: RS-485

The screen uses a custom backlight, which can display dissolved oxygen, temperature, PH, and a real-time clock. 
Manual calibration of salinity, air pressure and KB value to ensure accurate measurement value.
