Product information "Testomat® LAB Monochloramine NH2CL"

Testomat LAB Monochloramine – Analyzer for Monochloramine

Continuous measurement of monochloramine using the DPD method

The Testomat LAB Monochloramine NH2CL is an online analyzer designed for the continuous photometric determination of monochloramine in process and drinking water.

The measuring range for monochloramine (NH2CL, calculated as Cl2) is 0 to 5 ppm (resolution 0.1). The analysis is performed by dosing two reagents. After a reaction time of approximately 60 seconds, the measurement result is available. The Testomat LAB NH2CL has been developed for use in multi-parameter systems and for connection to higher-level control systems.

Key performance features of the Testomat LAB for monochloramine measurement

Maintenance requirements are low thanks to minimal reagent consumption and optimized water detection. A multilingual menu structure as well as parameterization via SD card or the Servicemonitor software make installation and adaptation to individual measurement tasks particularly user-friendly.

In addition to the 4–20 mA output for transmitting measurement values, this series is equipped with an RS232 interface for transmitting measurement data as well as error and status messages. All data are continuously recorded on the integrated SD card or an optional SDHC card (2 GB) in CSV format and are available at any time for detailed evaluation.

Technical highlights and performance profile of the Testomat LAB for monochloramine monitoring

Technical features include peristaltic pumps, a space-saving design, automatic venting of the indicator line, an integrated self-test, and firmware update capability via SD card.

The Monochloramine NH2CL and NH2CL-R stand out with the following functionalities:

  • RS232 interface for transmission of measurement values and error messages
  • Parameterization via SD card or the “Servicemonitor” software (Mini-USB device side to USB 2.0, e.g. PC or notebook)
  • Multilingual menu navigation (German, English, French, Dutch)
  • Firmware update via SD card
  • Compact design
  • Optimized water detection based on an optical measurement principle
  • Integrated self-test with continuous monitoring
  • Optimized reagent set with reduction from three to two reagents

Proven performance profile

  • Highly accurate peristaltic pumps
  • Reliable, low-maintenance operation
  • Minimal reagent and water consumption
  • 4–20 mA analog output for transmission of measurement values
  • RS232 interface for transmission of measurement values and fault messages
  • Common alarm output
  • Optimized reagents: only two reagents required for monochloramine determination
  • Optimized reagent containers with matched fill volumes so that both containers are depleted at the same time

Additional functions of the NH2CL-R version

Parameterization and reading of device parameters via the RS232 interface.

Analysis triggering:

  • Automatic interval operation (interval pause adjustable from 10 to 60 minutes)
  • Measurement phase mode (start signal triggers a sequence of analyses for 10 minutes up to 12 hours)
  • External analysis input (start/stop)
  • Manual start

Optional accessories

  • OLED display
  • Protective cover to increase the IP protection class

Testomat LAB OLED display module for displaying measured values, front view with measurement display
Testomat® LAB OLED display module for measured value visualization
Product number: 37764

256x64 2,8", yellowFeatures: When the device is switched on with the display plugged in, the installed software version is displayed during the boot process. This  allows you to visually check the current software version after a software update. After a measurement has been completed, the measurement result is  shown in the selected display unit. The display value is retained until the end of the next measurement and is then updated to the new measured value. If a fault occurs during the last measurement, the display shows “xx x x x selected display unit”. If it is a temporary fault, the Alarm function key flashes at the same time (see Temporary faults in the manual). In this case, the device will start a new measurement once the programmed analysis interval has expired. If the error is still present, the indication on the display remains and  the Alarm function key remains illuminated. In this case, no further measurements are made during programmed analysis interval and the device switches to standby mode. If the fault is no longer present, the measurement result is shown on the display once the measurement has been completed and the device switches back to normal operating mode.
