WIZ in-situ probe

Product Name:WIZ in-situ probe
Product Description:Water In-situ analyZer (WIZ) is the state of the art portable “in-situ” probe, to measure up to four chemical parameters continuously in surface waters or marine environments. The innovative design allows an easy handling and field deployment by the user. WIZ probe allows, in the standard configuration, the detection at trace levels of four nutrient parameters (orthophosphate, ammonia, nitrite and nitrate). WIZ probe autonomously manages the well known spectrophotometric wet chemistries and an advanced fluorimetric method for ammonia measurement. Analytical methods have been developed for several other parameters including silicates, iron and trace metals which are available on request. The WIZ probe is composed as standard by the analytical unit and the reagents canister; standard accessories are the mooring frame, 10 m submergible 12 Vdc + RS-232 serial cable and the flight case; a second reagent canister is suggested to quickly replace reagents on field. The probe can be powered by an external 12 Vdc source. Usually a 25 microns filter with antifouling capability (manual cleaning) is mounted on the sample inlet. The design and compact size allows an easy deployment from coastal buoys and floating platforms; the stand-alone installation layout including auto-cleaning filtration system, autonomous photovoltaic panel power supply, rechargeable battery and WIZlog data-logger
