INDUSTRIAL INSTRUMENTS

THE NEXUS.6500 SERIES DEVELOPED FOR WATER TREATMENT AND INDUSTRY, ALLOW THE MEASURING OF: pH/REDOX, CONDUCTIVITY, TURBIDITY, CHLORINE, OXYGEN 
2 ANALOGUE OUTPUTS output 1 programmable for measure, output 2 programmable for measure/temperature/PID regulation, outputs limits are freely programmable between the range of measures 
4 DIGITAL OUTPUTS on/off set point: set of the operating range (hysteresis /direction) and of start/stop time 000÷999 sec 
PID REGULATION pulse frequency or PWM (2 set point) 
ALARM reporting: instrumental anomalies, minimum, maximum, set point delay, permanence time (Live Check) 
ELECTRODES WASHING programming of the time leg, frequency: 00:00÷24:00 hh:mm, minimum time leg: programmable, during the washing phase, all digital and analogue outputs are freezed

WATERPROOF VERSION 144x144x120 mm
