HydroCycle-PO4 in-situ soluble phosphate analyzer
The Sea-bird Scientific HydroCycle-PO4 analyzer using WET Labs advanced technology is specially designed for long-term online monitoring of dissolved phosphate in water bodies rich in biomass. The HydroCycle-PO4 measurement method is mainly based on the US EPA standard method, which perfectly combines the precise microfluidic technology of WET Lab with the optical components, providing good accuracy and accuracy for the field detection of nutrients.
Because the HydroCycle-PO4 analyzer is equipped with a convenient in-situ kit and reagents, it can realize in-situ automatic monitoring of phosphate; it is very suitable for long-term online monitoring in unattended areas. The reagent kits of the instrument distinguish the types of reagents by color, and each kit is installed with a position code, which is very convenient for users to replace during field operations. In addition, Cycle P is equipped with NIST standard materials, which can be used for in-situ automatic peak calibration, allowing users to evaluate the quality of the data measured by the instrument and rest assured of the quality of the data collected by the instrument. The user can set the calibration frequency according to the usage.
The intuitive software interface is equipped with all necessary functions, for example, setting up the instrument, performing standard inspection and data download. In addition, you can graph real-time data and downloaded data to clearly show the trend of data changes.
Used for continuous long-term online monitoring or real-time monitoring of dissolved phosphate in the following water bodies:
Lakes and reservoirs
Streams, rivers, channels or ditches
Very suitable for monitoring:
Point source and non-point source nutrient input
Environmental dynamics and changes
Performance characteristics and advantages
Durable — The water inlet provides a double barrier of copper mesh and 10 µm stainless steel filter membrane to provide excellent anti-fouling capability for the instrument.
Accuracy-Nanomolar resolution and optical reaction cells that are not susceptible to scattering interference
Cost-effective-can measure more than 1000 samples, including on-site peak calibration for QA / QC, and a typical deployment cycle of up to three months, reducing on-site operating costs.
All meters are calibrated when they leave the factory and are equipped with NIST standard materials.
Customers can arrange the calibration frequency by themselves.
Intelligent sampling can reduce power consumption
The software is easy to use and simple to operate.
