What is MEKO measured for?

MEKO (methyl ethyl ketoxime) is an oxygen binding agent that is used as an alternative to DEHA and sodium sulphite in steam boiler systems. It has the advantage that it remains stable even at high temperatures and does not form any decomposition products that contaminate the steam.

Precise dosing of MEKO is crucial for optimum corrosion protection. The photometric measurement enables an objective and precise determination of the concentration.

MEKO is preferably used in high-pressure steam boilers and in systems where steam cleanliness is particularly important.

How does the test set work?

The CALDUR® MEKO Test Set – Photometric is based on the ferrozine method. The reagents form a color complex with MEKO, the concentration of which is determined photometrically using the WINLAB Data Line photometer.

Advantages of the CALDUR® test set

• Measuring range 0.5 – 10 mg/l MEKO

  Covers the practical dosing range

• 100 provisions per set

  Economical for regular checks

• High precision due to photometric evaluation

  Objective measurement results for optimum dosing

• Adapted to WINLAB Data Line photometer

  Optimum compatibility

What is MEKO measured for?

MEKO (methyl ethyl ketoxime) is an oxygen binding agent that is used as an alternative to DEHA and sodium sulphite in steam boiler systems. It has the advantage that it remains stable even at high temperatures and does not form any decomposition products that contaminate the steam.

Controlling the MEKO concentration is essential to ensure sufficient oxygen binding in the boiler water and at the same time to avoid overdosing. Typical target values are between 1 and 5 mg/l MEKO in the feed water.

MEKO reacts with dissolved oxygen and thus protects the metallic surfaces of boilers, steam pipes and condensers against oxygen corrosion.

How does the test set work?

The CALDUR® MEKO Test Set – Colorimetric is based on the ferrozine method. After adding two reagents to the water sample, a characteristic coloration develops within 8 minutes, the intensity of which is proportional to the MEKO concentration.

The measured value is determined by direct color comparison with a supplied color chart.

Advantages of the CALDUR® test set

• Practical measuring range 0.5 – 10 mg/l MEKO

  Covers the entire dosing range in boiler systems

• 100 provisions per set

  Economical for regular checks

• Quick analysis in 8 minutes

  Results directly on site at the boiler system

• Proven ferrozine method

  Selective and reliable for MEKO

• Robust plastic housing with hinged lid

  Safe transportation and protection of reagents
