Introduction to Horiba W-20 series multi parameter water quality monitoring instrument from Japan:

The W-20 series water quality monitoring system is a great choice for evaluating and testing various water quality, including oceans, rivers, dams, well water, surface water, urban water, rainwater runoff, lakes, ponds, and fishing grounds. It condenses HORIBA's years of research and development in electrical technology into a 47mm diameter probe, independently pioneering applications in high-pressure deepwater fields and enabling high-precision simultaneous measurement of 13 parameters. The W-20 system is compatible with GPS and data retrieval functions, and can be connected to a computer for processing and handling of data. Recording the collected data on the probe every 15 minutes can achieve continuous on-site monitoring for up to a month.

Features of the Horiba W-20 series multi parameter water quality monitoring instrument from Japan:

Record data continuously for one month

The measurement unit has a built-in storage function that can continuously record measurement data for one month
During the measurement process, no operator is required. Simply place the measuring unit (without connecting wires) in water to continuously measure for one month and store the data
Data storage can be transmitted remotely. *Measure data with a 15 minute interval

Measurement depth can reach up to 100 meters

Strong durability and pressure resistance, the newly developed electricity can measure real-time data at a depth of 100 meters
Very suitable for fixed-point monitoring and investigation of oceans, lakes, dams, etc. The measurement method is simple and the data accuracy is high

Simultaneously monitor 13 parameters

The W-23XD is capable of simultaneously monitoring 13 parameters. (pH, dissolved oxygen, conductivity, specific gravity of seawater, and various ions)
Faster and simpler than older models, with stronger monitoring capabilities.

Japanese Horiba W-20 series multi parameter water quality monitoring instrument parameters:

Note: The accuracy ratio value is obtained based on the detection value of the midpoint between two standard solutions after two-point calibration (at room temperature), and the percentages of repeatability and accuracy are based on full scale.
*1: Cannot detect organic solutions and strong acid and alkali solutions.
*2: The detection depth for nitrate ions, chloride ions, and fluoride ions is 100 meters, the detection depth for calcium ions and ammonia ions is 15 meters, and the detection depth for potassium ions is 3 meters
*3: Automatic data measurement based on 15 minute intervals. If there are a large number of crustaceans or algae around the detection point, regular maintenance and calibration must be carried out.
