Thermo Scientific Alpha pH 560

Product Features Alpha pH 560 limit control meter simplifies the task of controlling several processes with two set-point relays. Separately adjustable high and low hysteresis ensures chatter-free signals, preventing false alarms and unnecessary down-times. :: Separately adjustable High/Low hysteresis with user-adjustable time delay of up to 2000 seconds for minimal chattering and false alarm     :: Two switching contacts as set-point relays     :: Large UV Light protected LCD with backlight     :: Symmetrical Mode option gives clear, accurate readings in electrically noisy ambient     :: Push button operation for easy set-up programming and customization     :: US and NIST auto buffer recognition for quick, easy calibration     :: Reliable, accurate measurements at different temperature with Automatic Temperature Compensation
