Testomat® LAB Monochloramine NH2CL

Product number: 116109
Product information "Testomat® LAB Monochloramine NH2CL"
The Testomat® LAB Monochloramine NH2CL and the Testomat® LAB Monochloramine NH2CL-R  are online analyzer that photometrically measures the content of monochloramine in process water. The instruments are used for continuous monitoring of process quality, for example in cooling circuits. Another application is the use in the environment of water treatment and drinking water plants, for process monitoring, as well as the monitoring of ther decay behavior in cooling towers after shock chlorination. 
The measuring range for Monochloramine (NH2CL, calculated as Cl2) is 0 to 5 ppm (resolution 0.1). The instruments operates according to the DPD method based on EN ISO 7393-2. The analysis is performed by adding two reagents. After a reaction time of approx. 60 seconds (dosing and measuring time without rinsing time) the measuring result is available. 

Please note that the Testomat® Monochloramine NH2CL and NH2CL-R are developed for use in multiparameter systems or for connection to a higher-level control system. 
In addition to the 4-20 mA output for transmitting the measured values, this series has an RS232 interface for transmitting the measured values and error & status messages. Furthermore, all data are continuously recorded on the integrated SD card or optionally available SDHC card (2Gbyte) as a file in CSV format structured and can be used at any time for detailed observations.

The Testomat® LAB Monochloramine NH2CL and NH2CL-R convinces with new functionalities:
  • Execution of parameterization by SD card or the "Service Monitor" software via mini-USB (on the device side) to USB 2.0 (for example PC/notebook)
  • Multilingual menu navigation software in German, English, French, Dutch
  • Firmware update via SD card
  • compact design
  • optimized water detection based on an optical measuring method
  • optimized reagent set for total chlorine measurement (reduction from three to tow reagents for total chlorine)
  • Integrated self-test with continuous monitoring
  • Automatic venting of the indicator line 

Additional functions of the NH2CL-R version: 
Parameterisation and readout of the unit parameters via the RS232 interface

Tried and tested performance profile: 
  • High-precision peristaltic pumps
  • Reliable and low-maintenance operation
  • Minimal reagent and water consumption
  • Analog output 4 - 20 mA for transmission of measured values
  • RS232 interface for transmission of measured values & fault messages
  • Common alarm output
Analysis triggering:
  • Automatic interval operation (interval pause adjustable from 10-60 minutes)
  • Measuring phase mode (start impulse triggers a sequence of analyses for a period of 10 minutes to 12 hours)
  • External analysis input (start/stop)
  • Hand start

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.
