Water Analysis Kit
Introduction
The kit is used for assessment of water quality for potable water, industrial waste treatment plants etc. The device consists of a pH measuring unit, a temperature measuring unit, a dissolved oxygen measuring unit, a conductivity measuring unit and an ORP measuring unit, each can be operated independently.
The pH of the sample is measured with combined glass calomel electrodes using a high input resistance FET (Field Effect Transistor) amplifier system.
A platinum electrode in conjuction with a reference (ex.saturated calomel electrode) from the measurment system for ORP measurements. Conductivity coil with platinised platinum electrodes and with a cell constant of 1.0 +/- 0.01 is used for the measurement of electrical conductivity of the sample solution.
The Dissolved oxygen of the sample is measured using a membrane covered polorographic detector, which produces a current proportional to the dissolved oxygen in the sample.
Digital display is used for all the above parameters by proper calibration in their respective modes.
