Overview
Enviro Test Construct 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.
