The Conductivity Meter is the answer to low cost general purpose instrument to measure conductivity. The unit measures conductivity spread over 5 scales ranging from 100µmhos/cm F.S. to 1000 mMhos/cm. The conductivity is displayed by a moving coil panel meter. Cell coustant adjustment is also provided. Thus, it is a useful instrument for accurate conductivity measurements without further calculations of cell constant multiplication. The use of solid state IC circiutary makes the instrument versatile and reliable. The Conductivity meter is useful for water quality control in boiler feed water testing, agriculture and soil analysis laboratories, swimming pools, fertilizer plants, petrolium refineries, chemical and petrochemical complexes, water works department, transport undertaking, textile plants, rayon and silk mills etc.
