DESCRIPTION

U-50 Multi Parameter Water Quality Meter

main features
Equipped with a built-in GPS receiver module, it can simultaneously record the coordinate data of the sampling location.
Large screen LCD display, simple and easy to use, with backlight design, displaying 11 parameter readings on the same page for easy reading.
Multi parameter integrated electrode, capable of simultaneously detecting 11 water quality parameters: pH, potential difference, oxidation-reduction potential (ORP), dissolved oxygen (DO), conductivity, salinity, total dissolved solids content (TDS), seawater density, temperature, turbidity, and water depth.
Patent single key multi parameter automatic calibration function, only one step, using one standard solution to synchronously calibrate pH DO、 Conductivity, turbidity, depth and other parameters.
All electrodes can be replaced independently, and the electrode connector adopts a waterproof quick connector design, which can quickly disassemble and assemble the electrodes.
Random professional data software, capable of creating charts and tables, with powerful functions that users can customize according to their needs, and easy to operate.
• Automatic locking reading function, convenient for data comparison, USB cable and software, transmitting data to computer for analysis.
The sensor can be completely submerged in water and is made of waterproof, anti-collision, and wear-resistant materials, with excellent durability.
