产品概述与应用
The Alpha COND 560 controller simplifies process control with separately adjustable high/low hysteresis, and two switching contacts that act as set-point relays. Advanced control feature allows user to set alarm delay of up to 2000 seconds, preventing false alarms and unnecessary down-times.
High Accuracy - ±1 % accuracy across six Conductivity ranges
Advanced Control - Separately adjustable High/Low hysteresis with user-adjustable time delay of up to 2000 seconds for minimal chattering and false alarms
Flexible Configuration - User-selectable range, cell-constant and temperature coefficient to suit different application needs, including pure water measurements
Dual Relay Control - Two switching contacts as set-point relays
Clear Display - Large UV Light protected LCD with backlight
Easy Operation - Push button operation for easy set-up programming and customization
Temperature Compensation - Reliable, accurate measurements at different temperature with Automatic Temperature Compensation
