Summary
Product identification
The Testomat 2000® DUO is an online analysis instrument for determining and monitoring:
- Residual total hardness (water hardness)
- Residual carbonate hardness
- Minus m-value
- p-value
The instrument can measure two parameters at one measuring point or two measuring points with different or the same parameters.
Performance Specifications
- Menu-driven operation and programming with a plain text display.
- Freely selectable hardness units: °dH, °f, ppm CaCO₃, or mmol/l.
- High measuring accuracy via a precise piston-dosing pump.
- Analysis initiation:
- Automatic interval operation (interval pause settable from 0-99 minutes).
- External control.
- Quantity dependent via impulse water meter.
- Two independent limit values with hysteresis (1, 2, or 3 bad analyses) and settable switch functions.
- Monitoring of two measuring points (change-over via external solenoid valves).
- Internal error documentation.
- Programmable service address and maintenance interval.
- 500 ml indicator storage bottle for extended operating periods.
- Optional: Interface card (0/4-20 mA or 0/2-10 V) and Interface RS 232 (for a protocol printer).

- If the measuring value is outside the range (e.g., for TH2005):
- Falling below:
< 0.05°dH - Exceeding:
> 0.50°dH
- Falling below:
Operating Limits
- Water Pressure: 0.3 to 8 bar (instrument is factory set for 1 to 8 bar; flow controller valve body must be removed for 0.3 to 1 bar range). Avoid strong pressure fluctuations.
- Measuring Water Temperature: 10 °C to 40 °C. For temperatures above 40 °C, a KCN type cooler should be installed.
Feed Water
- Measured water is taken from the main water line of the water treatment plant.
- Standard inlet connection: Plug connector for plastic hoses 6/4 x 1 (external diameter 6 mm / internal diameter 4 mm, wall thickness 1 mm).
- Maximum inlet hose length: 5 m.
- For operation at 0.3 to 1 bar or with a booster pump, the valve body must be removed. The pump should have a feeding capacity of 25-35 litres/hour and be resistant to the medium.
Product Water
- Water outlet connection: Opaque outlet hose (internal diameter 14 mm).
- The outlet hose must be laid without backwater or siphoning effect, e.g., via an open funnel to the drain.
Electrical
- Mains Voltage: Connect only to the specified mains voltage (refer to the rating plate for 24 V / 115 V / 230 V).
- Power Consumption: Not specified in the extract.
- Relay Outputs: Max. 240 VAC, 4 A for all listed outputs (Flush OUT, Limit value outputs LV1/LV2, Measuring points 1/2 OUT, AUX OUT, Alarm OUT, Maintenance OUT).
- Interface Options:
- Galvanically separated current interface: 0/4-20 mA.
- Galvanically separated voltage interface: 0/2–10 V.
- RS232 interface for printer.
Mechanical / Hydraulic
- Dimensions: Not specified in the extract.
- Weight: Not specified in the extract.
- Hose Connections:
- Inlet: 6/4 x 1 mm plastic hose.
- Outlet: 14 mm internal diameter opaque hose.
- Measuring Chamber Fill Time: 2 to 6 seconds.
