DYS-1 PH Dissolved Oxygen Meter Handheld Do Meter 3v - 6v

PH and Dissolved Oxygen Meter Dissolved Oxygen PH Meter do Meter Handheld Dissolved Oxygen Meter


Dissolved oxygen measurement by sensor method


The most popular method for dissolved oxygen measurements is the use of dissolved oxygen meters and sensors. While the general categories of dissolved oxygen sensors are optical and electrochemical sensors, electrochemical sensors can be further subdivided into polarographic, pulsed polarographic and current sensors. In addition to standard analog outputs, some of these dissolved oxygen sensor technologies can also be used in smart sensor platforms with digital outputs.


DO sensors can be used in the laboratory or in the field.DO sensors can be designed for biochemical oxygen demand (BOD) testing, field sampling or long-term monitoring applications. Dissolved oxygen meter, water quality probe or data logging system can be used to record the measurement data obtained using DO sensors.


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, real-time clock.

Manual calibration of salinity, air pressure and KB value to ensure accurate measurement value.
