DulcoMeter Dialog (DACb)

✔ Simultaneous measurement 3 items enable water quality indication and drug injection control in all industries
✔ P / PID compatible for chemical injection pump, and feedforward control is also possible
✔ Various control outputs (pulse signal, time division relay, analog signal, etc.)
✔ 20 years worth of measurement data can be recorded on the SD card
✔ Can be linked with external devices using Ethernet (LAN) / Modbus

Features

● Dalkometer Dialog DAC is a multimeter that can simultaneously measure and control any 3 types of sensors from all 12 types of prominent sensors such as pH / ORP, residual chlorine, chlorine dioxide, peracetic acid, hydrogen peroxide, etc.
● It has a data log function to the SD card, and one unit can perform the three functions of measurement, control, and recording. In addition, when the residual chlorine sensor and pH sensor are combined, the correction display based on the pH value of residual chlorine is supported.
● Regarding chemical injection control, in addition to the conventional P / PID pulse control, time division control, and analog control, a feedforward control function and a target value change function from a remote location can be obtained by inputting 4 to 20 mA DC from a flow meter of another company. Is also installed.
