Online Optical Measure Water Dissolved Oxygen Probe DO Meter Price for Aquaculture
Several factors can affect the cost of a dissolved oxygen sensor and meter. The type of sensor, as mentioned earlier, is one of the most significant factors. The brand, accuracy, and durability also play a role in determining the cost.
Furthermore, additional features such as temperature compensation, automatic calibration, and digital interfaces can increase the price of both the sensor and meter. These features can be beneficial for applications that require precise and frequent measurements.
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.
