Product Overview:
The Electronics India (EI) Model 191 is a robust and comprehensive Deluxe Digital Water and Soil Analysis Kit, designed for accurate measurement of critical water and soil quality parameters. This instrument is ideal for environmental monitoring, agricultural applications, and laboratory analysis, combining high precision with complete portability.
Key Features and Portability:
This all-in-one kit offers measurement capabilities for eight parameters: pH, Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Oxidation-Reduction Potential (ORP or mV), Salinity, Temperature, and Turbidity.
The unit features a 3½ Digit LCD Display for clear readings. For maximum flexibility, the kit is Mains cum Battery Operated, utilizing an Inbuilt Chargeable Battery as well as 230V AC power supply. The entire system, including all necessary sensors and accessories, is housed within a durable ABS Plastic Briefcase, making it highly suitable for both fieldwork and demanding laboratory environments.
Comprehensive Measurement Capabilities:
The Model 191 specifically includes dedicated functions for turbidity measurement, making it a versatile tool for analyzing water clarity. The instrument uses a Gold/Silver Amperometric Probe for Dissolved Oxygen measurement and a Semiconductor Type sensor for temperature readings. The pH measurements benefit from manual temperature compensation across a 0–100 °C range, ensuring accurate results regardless of thermal variations.
The kit is supplied complete with standard accessories necessary for immediate operation and comes with a 1 Year Warranty.
