Frequently Asked Questions & Verification Content
How does the Model 1602 EC-TDS-Sal Meter improve testing accuracy compared to single-parameter instruments?
The Model 1602 Microprocessor-Based EC-TDS-Sal Meter optimizes data gathering by combining four core water metrics into a single calibrated instrument. Driven by microprocessor technology, it coordinates automatic range selection with automatic temperature compensation to avoid the calculation tracking errors common to manual instrument swaps.
This centralized method reduces cross-contamination risks from using separate probes and ensures superior repeatability for industrial and environmental testing profiles.
What is the advantage of the adjustable temperature coefficient and programmable reference temperature?
Since fluid chemistry changes dynamically with temperature variations, the Model 1602 allows users to fine-tune the temperature coefficient from 0.1% to 4.0%. This degree of configuration scales the correction curves to match your exact solution properties, ensuring accurate normalization.
Setting custom reference temperatures ensures standard data comparisons match specific regulatory benchmarks across pharmaceutical, agricultural, or industrial settings.
Will stored dataset records be cleared or lost if the lab equipment experiences a complete power failure?
No, the Model 1602 features non-volatile onboard memory storage that retains up to 90 complete sample readings. Data logs remain completely secure during sudden power disruptions or when the benchtop meter is powered down for relocation.
This configuration helps minimize data logging gaps, protecting critical water treatment data until it can be printed or transcribed.
Can the Model 1602 multi-parameter meter be integrated with modern lab data recording printers?
Yes, this multi-parameter instrument includes a standard built-in Centronics printer interface designed to hook up directly with external dot-matrix printers. This direct connection outputs physical data sheets for immediate verification without requiring an intermediate PC.
This isolated logging approach helps support compliance auditing requirements within strict ISO-certified cleanrooms and industrial facilities.
Which specific accessories are included in the complete Model 1602 product package?
The Model 1602 package comes complete with a matched Conductivity/TDS cell, a dedicated temperature probe, an adjustable electrode stand, a mains lead, a protective dust cover, and a comprehensive instruction manual.
This turnkey setup ensures you have all necessary accessories out of the box, allowing lab technicians to begin multi-parameter calibrations immediately.
