产品概述与应用
The Alpha COND 1000 features up to ten selectable conductivity ranges and corresponding cell constant K values, easily configured through a six-button keypad. Adjustable temperature co-efficient and ultrapure water compensation option allow measurements in broad-range applications, from ultrapure water to high-conductivity samples.
High Accuracy - ±1% full scale accuracy across ten different Conductivity ranges
Temperature Compensation - Adjustable temperature coefficient from 0.0 to 10.0% for higher accuracy
Pure Water Optimization - Pure water compensation option corrects non-linearity of pure water temperature correction curves in ultrapure water applications
Flexible Temperature Control - Option of Auto or Manual Temperature Compensation. Three-wire system compensates for cable-length resistance errors
Calibration Memory - Meter displays electrode information after each successful calibration. Previous calibration data is retained in the event of unsuccessful calibrations
Line Adjustment - Feature corrects long cable resistance errors – an important feature useful in applications involving high conductivity measurements
Quality Output - Galvanically-isolated, scaleable 0/4 to 20 mA output for high-quality output on peripheral devices
Use for virtually any batch or online applications where rapid, accurate control. Great for OEM/system integrator.
Use in applications involving agriculture, chemical processing, boiler and water heaters, wafer-fab, microprocessor manufacturing, pharmaceuticals, pulp and paper industries, and bleach manufacturing.
Use to treat batches of incoming process water, ultrapure water, boiler and feed water control.
Hook up to recorder for regulatory compliance data collection.
