Multi Parameter Meter - ph, orp, TDS, Salinity , Ec, DO and
HI-98194 Multiparameter Waterproof Meter
The HI-98194 from Hanna Instruments is a compact, rugged multiparameter water quality meter housed in an IP67 waterproof enclosure. Capable of measuring 12 parameters including pH, ORP, Conductivity, TDS, Resistivity, Salinity, Seawater, Dissolved Oxygen, Atmospheric Pressure and Temperature, it is designed for demanding field and laboratory applications where reliable, accurate measurement is essential.
The meter features a backlit graphic LCD for easy reading in low-light conditions, and an intuitive combination of dedicated and soft keys with multi-language support. The HI-7698194 probe connects via a quick-connect DIN connector with colour-coded, field replaceable sensors that are automatically recognised on connection. Data logging of up to 45,000 samples can be transferred to a PC via the HI-920015 micro USB cable and Hanna software. The standard probe cable is 4m.
