This document describes two systems for testing water and soil quality: Polysense Aqua tests water samples for parameters like pH, conductivity, salinity, and compares results to BIS standards; Polysense Soil tests soil samples for nutrients like nitrogen, phosphorus, potassium, pH, and salinity. Both systems were developed by an IIT Bombay professor to evaluate certain physical and chemical properties of water and soil.

1. Drinking Water and Soil Testing Systems
• System for testing water, Polysense Aqua is the launch product of the company.
Tests the potability of a water sample by evaluating certain physical and chemical parameters and
comparing them with standards specified by Bureau of Indian Standards (BIS)
