Testomat 2000 DUO

Summary

Product identification

• Product Name: Testomat 2000® DUO
• Description: Online analysis instrument for water hardness, carbonate hardness, p-value, or minus m-value.

Intended use

The Testomat 2000® DUO is designed for the automatic determination and monitoring of residual total hardness (water hardness), residual carbonate hardness, as well as the minus m-value and p-value in water. Measurement parameters and ranges are determined by indicator selection and user programming.

Performance specifications

• Menu-driven operation and programming via plain text display.
• Measures residual hardness, total hardness, carbonate hardness, minus m-value, p-value via indicator selection.
• Freely selectable hardness unit: °dH, °f, ppm CaCO₃, or mmol/l.
• High measuring accuracy provided by a precise piston-dosing pump.
• Analysis initiation methods:
  • 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.
• Programmable maintenance interval for maintenance requests.
• 500 ml indicator storage bottle for extended operating periods.
• Optional: Interface card (0/4-20 mA or 0/2-10 V), Interface RS 232 (for protocol printer).
