Product Overview
The TP3500 portable dissolved oxygen analyzer is developed according to the requirements of GB/T12157-2022 "Determination of dissolved oxygen in industrial circulating cooling water and boiler water" and HJ506-2009 "Determination of dissolved oxygen in water quality - Electrochemical probe method" standards, and is applied to the measurement of trace dissolved oxygen in solutions in various industries.
Features
*Chinese or English display, easy to operate, using high-resolution 256 × 128 dot matrix LCD display module.
*High precision measuring electrode, short response time, stable measurement, with a response time of less than 10 minutes when the saturated oxygen concentration in the air is below 5ug/L
*By using high-precision AD chips and microcontroller microprocessing technology, stable and accurate measurement of oxygen content is achieved, with low concentration resolution up to
To 0.0001 μ g/L
*Built in temperature compensation, salinity compensation, pressure compensation, accurate and reliable measurement of current water oxygen content value
*Built in RS232 communication protocol, can exchange data with the computer through Type-C port
*Built in RS485 ModBus RTU communication protocol, capable of real-time data acquisition with a computer through an interface
*Press the storage button in the measurement state, and the instrument will automatically store the oxygen content, saturation, temperature, set salinity value, set atmospheric pressure value, current value, and time on the measurement interface
*Oxygen concentration, saturation, temperature, time, current value, and status can be displayed simultaneously on the same screen
*Data loop storage function, automatically clearing overflow data, simple operation, easy query, power-off data storage for more than 10 years
