Måler og viser inntil 11 parameter samtidig. Måler pH, ORP, DO, Konduktivitet, salinitet, TDS, Spesifikk egenvekt sjøvann, temperatur, turbiditet, vanndybde. Innbebygget GPS.
Vannkvalitetsmålerne i U-50-serien fra Horiba er høykvalitets multiparameter instrumenter som gjør det mulig å måle/overvåke opptil 11 parametre med en og samme enhet, og med kun 1 sensor tilkoblet. Moderne og robust design, og brukervennlige funksjoner gjør instrumentet perfekt for feltovervåkning av f.eks. elver, grunnvann, sjøvann, oppdrettsanlegg, brønnbåter, etc.
Om HORIBA
HORIBA er et globalt selskap med et omfattende utvalg av velutprøvde instrumenter og systemer for bruksområder som spenner fra bilindustrien, prosess og miljøovervåking, in-vitro medisinsk diagnostikk, halvlederproduksjon og metrologi, til et bredt spekter av vitenskapelige R & D og QC målinger. Velprøvd kvalitet og god ytelse har gjort HORIBAs produkter til internasjonalt anerkjente merkevarer. Blant annet var HORIBA selskapet som laget den første pH-måleren så tidlig som i 1945.

12 channel parallel (This is availalble for U-52G, U-53G and U-54G.)
Note:
*Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20℃ and the backlight OFF.
*Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements against standard solution.
*Repeatability is measured by the ability to reproduce the results against the standard solution (at 25℃ normal pressure condition).
