Potassium hydroxide Analyser (KOH)

Potassium hydroxide with chemical formula KOH is one of the most used industrial liquid in the world. This chemical is easy to monitor eal time by means of ultrasonic spectroscopy.

Some points of use in the industry

• Pulp and paper
• Semicon & LCD industry
• Textiles
• Soaps and detergents

Technology

The technology of Ultrasonic Density is explained here.

Our probes

Arenal offers a variety of probes to measure KOH concentrations online:

1. For high concentrations KOH, our torroidal (electrodeless) sensor is suitable for the full range 0-40 wt% when the temperature of the liquid is within certain limits. As a standard we offer PEEK torroidal probes. Interested? Fill in the questionnaire.
2. For low concentrations, our contacting conductivity sensor is suitable for the range 0-2wt%. As a standard we offer PEEK/SS316 4 pole contacting probes. Interested? Fill in the questionnaire.
3. If highest accuracy is required on the full range, the ultrasonic spectroscopy sensor is the best choice. The acoustic graphs for density and speed of sound gives a continuous increasing signal between 0-50 wt%, but flattens out in the last part. This makes the sensor ideal for use in a broad range and for determining its concentrations on 4 digits over the full range. The materials used are PEEK, SS316 and zirconiumoxide (ZrO2).

Embodiments

When choosing ultrasonic spectroscopy sensors, we herewith help you selecting the correct products. Arenal offers solutions for applications with a variety of embodiments. Actually in most cases only the probe size, body shape, body material and sensor material changes, while the transmitter and Analysers keeps the same.
