Frequently Asked Questions & Technical SEO Integration
What are the primary applications of the ESICO Microprocessor Based pH-EC-TDS Meter 1615?
The ESICO Microprocessor Based pH-EC-TDS Meter 1615 is an integrated laboratory analyzer used for critical water quality monitoring across multiple sectors. It delivers simultaneous testing for solution pH, electrical conductivity, total dissolved solids, and temperature within industrial, environmental, and agricultural frameworks.
This versatility makes it essential for pharmaceutical processing, municipal wastewater plants, aquaculture management, soil testing clinics, and specialized chemical analysis laboratories requiring rigorous multi-parameter assessment.
How does the automatic temperature compensation feature improve measurement accuracy?
The microprocessor pH-EC-TDS meter 1615 utilizes automatic temperature compensation to actively neutralize measurement drift caused by thermal changes in a sample. It cross-references electrochemical readings against temperature probe data to adjust calculation metrics automatically, ensuring reliable values across changing conditions.
Since pH, EC, and TDS variables are naturally temperature-dependent, this integrated processing eliminates manual mathematical adjustments and maintains stable laboratory reproducibility from 0 to 100°C.
What are the benefits of auto-ranging and auto buffer recognition capabilities?
These intelligent automation features simplify system calibration and minimize operator error. The ESICO Model 1615 automatically identifies standard pH buffers (4.00, 7.00, 9.20 pH) during calibration, while its auto-ranging system automatically switches to the ideal measurement scale when measuring high or low salinity solutions.
This eliminates the need for manual range switching across five conductivity and TDS stages, preventing errors from mismatched operational scales.
Can the ESICO Model 1615 retain testing data during power failures?
Yes, this microprocessor pH-EC-TDS meter features advanced internal memory capable of archiving 90 distinct analytical samples. This registry utilizes non-volatile flash core storage, ensuring that logged datasets remain completely intact even during sudden power cuts or instrument disconnections.
Stored records can be reviewed on the backlit alphanumeric LCD display or exported via the built-in Centronics interface for data compliance verification.
What accessories are included standard in the ESICO Model 1615 analyzer package?
The standard ESICO Microprocessor Based pH-EC-TDS Meter 1615 comes as a complete, field-ready package. It includes a high-performance pH combination electrode, a robust conductivity/TDS cell, a dedicated temperature probe, pH buffer tablets (4.00 & 7.00 pH), an adjustable electrode stand, a dust cover, and a comprehensive instruction manual.
This full complement of factory accessories allows immediate setup, calibration, and multi-parameter testing straight out of the box.
