Techical specification: Wall mounting 144x144 Measuring ranges: Dissolved Oxygen 00.0 ÷ 40.0ppm/mg/l. 0 ÷ 200% Saturation Resolution: 0.1ppm–mg/lt – 1% sat. Accuracy 0,5% f.s. Temperature: -10 ÷ 130°C Resolution: 0.1°C Automatic temperature compensation. Graphic display to visualise simultaneously: measurement, temperature, analogue and digital outputs (set point) condition, alarms. Internal data logger (16.000 records). Tabular or graphic stored data display with maximum, minimum and average values. Programming key pad with 5 keys. Function keys to direct access to the calibration menu and to the graphs of the stored measure. PID regulation to be set for analogue or digital output (PWM or Frequency ). Two digital Outputs to be set for set point, with programming of working range and activation time. Digital output for Alarm: minimum, maximum, delay of the set point, residence time (live check), malfunction. Digital output to be set for: Temperature set point or to control the rinsing cycle of the electrode with time and interval programming.. Digital input to be set for: external command of electrode rinsing cycle or for dosing inhibition 0/4÷20mA primary output with limits that can be programmed within the measurement range. 0/4÷20mA secondary output that can be programmed among: temperature/meas. repetition/PID function. RS485 serial output with MODBUS RTU protocol. Possibility to simulate the outputs via a keyboard.
