Local web server for app-free measurement, control and remote access with conventional 4-channel controller, for measurement and optional control of: pH, redox, free chlorine, total chlorine, chlorine dioxide, bromine, hydrogen peroxide, peracetic acid and many other parametres

• Operation via the browser on the third-party device (PC, smartphone, tablet) with access management
• RJ45 LAN port required, DHCP or fixed addressing
• LED display on device, or display-free settings via the network
• Data recording in the device on SD card or by remote access
• E-mail delivery of data and alarms to 3 configurable addresses
• General functions:
  • Calculation of the effectiveness of free chlorine, correction of the pH error of the chlorine mV sensors, monitoring for the mV sensor exceeding the measuring range, evaluation of empty signal switches, separate external dosing start via input, evaluation of inductive flow meters with (optional) volume flow compensation, evaluation of other reed contacts, guided calibration
• Inputs:
  • 4 electrically isolated slots for pH, redox or mV sensors according to the accessories list
