ESICO Microprocessor pH-EC Meter 1611 – Triple Parameter Water Analysis System
The ESICO Microprocessor Based pH-EC Meter Model 1611 is a highly advanced, solid-state laboratory instrument engineered for the simultaneous evaluation of critical water criteria. Manufactured by Environmental and Scientific Instruments Co. (an ISO 9001:2000 certified firm), this integrated analyzer combines premium digital signal processing capabilities with high-stability sensor workflows to measure pH, Electrical Conductivity (EC), and Temperature within a single, space-optimized benchtop chassis.
Perfectly tailored for modern analytics, the Model 1611 streamlines routine environmental testing, chemical processes, pharmaceutical quality checks, and agricultural research. By leveraging its interactive 16x2 backlit alphanumeric LCD and an intuitive 8-key splash-resistant membrane keypad, operators can execute compound calibration routines and read parameters in unstable field or industrial situations seamlessly.
Data integrity is supported by a rugged 90-sample internal non-volatile memory block that secures critical records even during absolute power failure conditions. Furthermore, the unit features built-in Centronics printer interfacing for dedicated physical data logging on standard dot-matrix peripherals, ensuring robust corporate workflow integration and compliance tracking.

Frequently Asked Questions & Technical Reference
What are the primary target parameters for the ESICO Microprocessor Based pH-EC Meter 1611?
The ESICO Microprocessor Based pH-EC Meter 1611 is a triple-parameter system designed to deliver precise readings for pH, Electrical Conductivity (EC), and Temperature within a single unit. It serves industrial, agricultural, and research laboratories needing accurate and stable water analysis configurations. This advanced solid-state instrument optimizes standard workflows by processing simultaneous data strings with minimal probe interaction metrics.
How does the auto-ranging feature on the ESICO 1611 system function?
The auto-ranging feature on the ESICO 1611 electrical conductivity system automatically selects the optimal measurement scale from five distinct ranges (0–20 μS to 0–200 mS). This ensures maximum operational resolution and eliminates manual scale adjustment errors during sample evaluation processes. The device continuously adjusts its algorithms based on the ionized content found inside the active solution matrix.
Does the ESICO pH-EC Meter 1611 retain analytical data if laboratory power goes out?
Yes, the ESICO pH-EC Meter 1611 features non-volatile data storage capable of securing up to 90 diagnostic samples indefinitely during absolute power loss. This capability prevents field or laboratory information loss, allowing teams to retrieve or print saved results when standard electricity supplies normalize. Users can confidently log values without worrying about local grid fluctuations.
What items are bundled within the standard product packaging for the Model 1611?
The standard ESICO pH-EC Meter 1611 configuration includes a specialized pH combination electrode, conductivity cell, dedicated temperature probe, heavy-duty electrode stand, calibration buffer tablets (4.00 & 7.00 pH), a protective dust cover, power mains lead, and an explicit instruction operations manual. This absolute turnaround bundle lets laboratories run analytical diagnostics immediately upon deployment.
What cleaning and maintenance protocols keep the electrodes performing reliably?
To maintain accuracy with the ESICO 1611, rinse electrodes thoroughly with distilled water between test samples, keeping the delicate glass pH bulb moist inside a 4.0 pH buffer solution. Conversely, store the conductivity cell dry after removing oily contaminants with a mild detergent option. Proper cleaning schedules prevent electrode drifting and extend total component lifespans dramatically.
