Product information "Testomat® LAB TH"
The Testomat® LAB TH and Testomat® LAB TH-R (Remote)determine the water hardness (residual total hardness) fully automatically by titration. The instrument is suitable for controlling the water quality of water treatment plants, drinking water plants, industrial boilers and for monitoring process water.

Please note that Testomat® LAB - TH and Testomat® LAB TH-R was developed for use in multi-parameter 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 TH and TH-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, Portuguese
  • Firmware update via SD card
  • compact design
  • optimized water detection based on an optical measuring method
  • Integrated self-test with continuous monitoring
  • Automatic venting of the indicator line

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

Tried and tested performance profile:
  • High-precision titration using a piston dosing pump
  • Reliable and low-maintenance operation
  • Minimal indicator and water consumption
  • Analog output 4 - 20 mA for transmission of measured values
  • Programmable hardness unit in °dH, °f, ppm CaCO3, mmol/l
  • Common alarm output
  • Indicator quantities: 500 ml bottles

Analysis triggering:
  • Automatic interval operation (interval pause adjustable from 0-255 minutes)
  • External analysis input (start/stop)
  • Hand launch

Optional accessories:
  • OLED display
  • Protecting cover to increase the IP protection class

We recommend the following accessories

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.

Testomat® indicator TH 2100 500ml.
Product number: 152100
500 ml bottle original Testomat® indicator TH 2100 for limit value: 1,00-10,00°dH for measuring residual hardness. °dH (resolution): 1,00-10,00 (0,20) °f (resolution): 1,79-17,9 (0,40) ppm CaCO3 (resolution): 17,9-179 (3,8) mmol/l (resolution): 0,18 -1,79 (0,04)

Testomat® Aerator R
Product number: 130009
Performance/execution: 24 V/50-60 HZ
Testomat® aerator for reducing the CO2 content. Capacity: Max. water throughput of 12 l/h when reducing the free carbon dioxide from max. 200 mg/l to below 20 mg/l.   A high carbon dioxide content in the sample water distorts the measurement results. Therefore, insert the small aerator R upstream of the Testomat® device to reduce the CO2 content in the sample water.   Dimensions (W x H x D): 150 x 500 x 100 mm Supply voltage: 230 V/50 Hz.   Attention: The mounting of the Aerator R has to be 3 meters over the device!
