Testomat 2000 THCL

Summary

Product identification

• Product Name: TESTOMAT® 2000 THCl
• Description: Combined Process-Photometer for total chlorine and Process-Titrator for water hardness.
• Functions:
  • Total Chlorine: 0 - 2.5 ppm (mg/l) via colorimetric analysis.
  • Water Hardness: 0.25 - 2.50 °dH via titration.

Operating limits

• Total Chlorine Measuring Range: 0 - 2.5 mg/l (ppm)
• Water Hardness Measuring Range:
  • 0.25 - 2.50 °dH (Resolution: 0.05)
  • 0.45 - 4.48 °f (Resolution: 0.1)
  • 4.47 - 44.7 ppm CaCO₃ (Resolution: 0.9)
  • 0.04 - 0.45 mmol/l (Resolution: 0.01)
• pH Range: 4 - 10.5
• Interferences:
  • Heavy-metal ions: Iron > 0.5 mg/l, Copper > 0.1 mg/l, Aluminium > 0.1 mg/l can affect color reaction.
  • Carbon Dioxide (CO₂): > 100 mg/l can affect analysis.

Feed water

• Temperature: 10 °C to 40 °C. Higher temperatures can damage components.
• Pressure:
  • Standard: Supplied with plug connector for 6/4 x 1 plastic hoses.
  • 0.1 to 1 bar: Remove valve body from regulator/filter housing.
  • Fabric reinforced hoses: Requires optional quick-acting coupling adapter.
• Connections: Sampling tube should be short, equipped with a shut-off valve, and taken vertically from the top of the main soft water line.
• Drain: Outlet pipe to drain requires a 14 mm internal diameter hose connection. A light-impervious hose is recommended.

Product water

• The device monitors feed water quality.

Electrical

• Mains Supply: 230 - 240 V AC (or 24V AC, check rating plate).
• Relay Outputs (max. load 240 V AC, 4 A):
  • Flush (External flush valve)
  • LV1 Limit value output 1 (Residual hardness)
  • LV2 Limit value output 2 (Chlorine)
  • Measuring point 1/2 switch-over
  • AUX Programmable function output
  • Alarm Fault message
  • Maintenance message
• Signal Inputs (Volt-free contacts recommended):
  • Start (External analysis start)
  • Stop (External analysis stop)
  • IN1 (External measuring point switch-over)
  • IN2 (Water meter input)
• Interface Output (Optional):
  • 0/4 - 20 mA (max. load 500 Ohm) for measuring value output.
  • Serial interface RS232 (requires optional plug-in circuit card RS910).

Mechanical / hydraulic

• Dimensions: See dimensioned sketch (360 x 266 mm shown).
• Hose Connections: Standard with plug connector for opaque plastic hoses 6/4 x 1. Optional adapter for quick-acting coupling available.
• Mounting: Unit should be fixed vertically. Ensure space for door opening (doors swing to the left).
• Internal Construction: Includes valve block, filter housing, measuring chamber, and multiple dosing pumps (TH2025, Cl2250A, Cl2250B, Cl2250C).
