JA PRO control instruments are a series of rack mounting (96x96) single reading systems with temperature reading, mA module and native Modbus. On/Off, impulsive proportional and PID are the main working modes.
It can set and monitor: pH, ORP, chlorine, total chlorine, free chlorine, chlorine dioxide, hydrogen peroxide, ozone, bromine or paracetic acid (depending on the probe) and conductivity with automatic range and select probe / product (Ohm - H3PO4 - H2SO4 - HNO3 - HCl - NaOH - NaCl - TDS / PPM) for best results. Probes are not included.
JA PRO models have: 2 setpoints (on/off, proportional), flow alarm, flow sensor stand-by input, 0-20 mA or 4-20 mA output proportional to read value and programmable in the reading range, alarm output.
Avalilable low voltage 9-18VDC or 18-36VDC power supply and IP54 protection cover.
JA PRO is equipped with mA module and MODBUS serial communication to be connected to other devices on RS485 networks and TCP/IP MODBUS.
