Frequently Asked Questions & Technical Compliance Documentation
What specific parameters can be analyzed using the Electronics India Model 191 Analysis Kit?
The Electronics India Model 191 Deluxe Digital Water and Soil Analysis Kit is an all-in-one system engineered to accurately determine 8 core scientific indicators. This professional instrument analyzes pH, Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Oxidation-Reduction Potential (ORP/mV), Salinity, Temperature, and Turbidity.
By housing all necessary premium testing probes and sensor interfaces within a single portable kit, it enables immediate field data gathering without requiring individual single-parameter meters.
How does the dual-power configuration of the Model 191 assist field scientists?
The Model 191 features a flexible Mains cum Battery Operated architecture that uses an Inbuilt Chargeable Battery alongside a standard 230V AC power terminal line. This dual configuration allows researchers to plug into standard laboratory mains power or rely entirely on independent internal battery storage for remote outdoor monitoring.
This design helps environmental engineering teams execute long-term tracking projects across rugged locations lacking direct electrical utility.
What type of sensors are utilized for Dissolved Oxygen and Temperature tracking inside this kit?
For precision Dissolved Oxygen (DO) analysis, the Model 191 includes an advanced Gold/Silver Amperometric Probe that optimizes electrochemical reaction paths. Thermal measurements are tracked concurrently via a solid-state Semiconductor Type sensor probe, which supports manual temperature compensation over a wide 0–100 °C range.
These industrial-grade sensors ensure steady, repeatable data tracking by protecting the system against common thermal interference or drift issues.
Is the Model 191 Deluxe Analysis Kit durable enough for challenging outdoor environmental fieldwork?
Yes, the entire Electronics India Model 191 system framework and its delicate testing sensors are housed inside a rugged, impact-resistant ABS Plastic Briefcase. This protective case shields the electronic components, glass tubes, and measuring electrodes against mechanical vibration and environmental hazards during fieldwork.
The secure interior compartments ensure all parts stay safe and properly aligned through rough transit over unpaved testing sites.
What standard accessories are provided with the initial purchase of the Electronics India Model 191?
