Digital 3-in-1 pH Conductivity Temperature Meter | Model 181 EI-DVI | Laboratory Benchtop Analyzer
Product Overview
The EI-DVI Digital pH, Conductivity & Temperature Meter Model 181 is an elegant, rugged, and most economical instrument designed for fast and accurate measurement of three critical parameters in any laboratory. This combination meter utilizes solid-state integrated circuit (IC) circuitry, making it versatile and reliable for complex analytical tasks. The meter is specifically engineered for monitoring acidity and alkalinity (pH), ionic content (conductivity), and temperature across a wide range of solutions.
Core Features
The Model 181 is built with performance and durability in mind, offering exceptional stability and usability:
• Triple Parameter Analysis: Combines pH, Conductivity, and Temperature measurement in a single benchtop unit.
• Highly Stable and Accurate: Engineered components ensure precise and consistent measurement results.
• High-Visibility Display: Features a bright red, 3½ digit, seven-segment LED display for clear reading in laboratory environments.
• Rugged & Reliable Design: Durable construction optimized for long-term use in demanding industrial and laboratory settings.
• Cell Constant Adjustment Facility: Includes a facility for adjusting the cell constant (0.2 – 1.8), providing flexibility for various conductivity probes and enhancing measurement accuracy.
• High Input Impedance: Input Impedance is greater than 10¹² ohms, minimizing electrical loading effects during pH measurement.
• Temperature Compensation: Offers manual temperature compensation for pH (0–100°C) and conductivity (0–50°C, adjustable based on temperature tables at 25°C).
Versatile Applications
The Model 181 meter is an extremely useful instrument across numerous sectors, supporting crucial water quality, chemical, and environmental testing:
• Water Analysis: Essential for monitoring natural water, sea water, drinking water, treated water, and waste water.
• Environmental Testing: Used widely in pollution and environmental testing, and public health engineering.
• Chemical Laboratories: Ideal for general chemical solutions, brine solutions, and monitoring acidity and alkalinity.
• Industrial Process Control: Applicable in various industries including sugar, cement, paper, pharmaceuticals, petroleum refineries, and brewery operations.
• Boiler Water Analysis: Crucial for controlling water chemistry to prevent corrosion and maintain system efficiency.
• Agricultural & Soil Labs: Used for soil analysis, determining soil pH, and testing nutrient solutions and irrigation water quality.
