Water Hardness Detection
Colormetry Hardness Detection System
Water hardness is a common cause of boiler damage. Typically, water-hardness levels are checked manually through the use of chemical reagents. Such measurements are time consuming and can result in incorrect readings.

Colormetry solves all these problems by offering automated reagent injection, mixing and evaluation integrated into the boiler control system.
  • Automatically monitors water quality
  • Controls MW regeneration if hardness is detected
  • Alarm and fault history logging
  • Easy reagent replacement
  • Compact design
  • Self-Calibrating
  • Connects Miura remote monitoring system (MOM) for added security and protection
  • Interfaces with BL boiler controller

Special Features
  • Totally automatic control. Simple and timesaving procedure
  • No routine calibration necessary
  • Set standard time period for monitor. (for example, every day between 9:00-17:00)
  • With remote control, initiate and terminate the monitoring system from outside the boiler room
  • Monitor hardness leakage at each set time (for example, every hour), which enables early detection of hardness leakage
  • Detect low levels of hardness leakage such as 1-2 mg/L by optically and electronically monitoring the color of sample water
  • The result of the evaluation for hardness level is shown on the digital screen (for example, 0-1 mg/L), which indicates the efficiency of water softener. Instant recognition of the stage of operation by digital signature
  • Buzzer alarms when any hardness leakage is detected. With the external alarm contact outlet, the alarm can be sent to a remote location
  • Equipped with self -check/ confirm function. In case the device faults, the main cause of the problem is shown in the same manner as the evaluation of hardness leakage
  • Memorizes date, time, duration of hardness leakage and time of reinstatement for up to three consecutive incidents. Memory function assists in analysis of the causes of hardness leakage
  • The cartridge contains all the necessary chemical reagents and can be replaced with a one-touch, simple motion. In normal operation the cartridge does not have to be replaced for approximately 4 months
  • Unique compact design automatic colorimeter device
  • Easy installation on the wall with mounting brackets attached to the device
  • One-touch connection of collection and drain lines to the device
Notes:
  • Use the supplied transformer to step down from the AC 120V to 24V and supply 24V to main unit
  • Even in standard case of hourly monitoring, Abnormally frequent detection of hardness may require more frequent replacement of the reagent cartridge than the normal 4 months
  • The inlet and outlet tubes are attached to the device
  • The mounting bracket is attached to the device
