Water analyzer AH-1

Magnesium contentcalciumcontinuous monitoring

About
AH-1 is an automatic on-line analyzer for continuous monitoring of total hardness (total concentration of calcium and magnesium salts) in aqueous streams. Designed for industrial water treatment, power generation, process control and environmental monitoring, AH-1 provides reliable potentiometric measurement with minimal reagent consumption and may be integrated into plant control systems.

Principle of operation
Potentiometric determination of total calcium and magnesium ion content using a solid-state potentiometric transducer, with digital data processing and temperature compensation.

Features and benefits

• continuous on-line monitoring for real-time process control;
• solid-state electrodes providing stable long-term performance;
• controlled hydrodynamic conditions at the primary potentiometric transducer;
• automatic temperature compensation to correct flow temperature variations;
• one-point calibration for simplified maintenance;
• programmable sample intake rate to match process requirements;
• digital signal processing with RS-485 and 4–20 mA outputs;
• built-in self-test diagnostics and status outputs (alarm, operation, user-defined).

Application examples

• monitoring of water pretreatment and softening units at power plants;
• control of artesian well water softening installations;
• quality control of feed water and boiler feed for thermal power plants;
• monitoring turbine condensate in steam power stations;
• water quality control for food and beverage production lines.

Equipment and options

• AH-1 total hardness monitor;
• spare parts and accessory kits;
• reagent set for preparation of calibration solutions;
• hydro seal for analysis of pressurized samples;
• flow switching unit and valves for multiple sampling points.
