TDS Meter
Digital Conductivity Meter 304 and 307 are convenient instrument for routine measurements of conductivity of various electrolytes such as Caustic content of rinse water, Electrolytic impurities in Distilled / Demineralised water, Sulphuric Acid concentration in pickling baths, Anodizing tanks, Soil Conductivity and other applications. The instrument uses state of the art IC technology and consumes very little power. Source frequency (100 Hz or 1 KHz) gets automatically selected in the appropriate range. Type 307 also measures Total Dissolved Solid (TDS) in liquid. The unit is housed in compact, shock/rust proof & light weight injection molded cabinet.
