These devices incorporate a platinum flat ion electrode for microvolume measurement. Only a few drops (0.3 ml) are required to provide a fast and accurate analysis.

It can be used as a traditional ORP meter by immersing the electrode in a liquid.

Main features:

Temperature compensation.
Automatic calibration: recognizes the calibration solution.
Detection of the stability of the result.
Waterproof (IP67).
Automatic selection of the appropriate range.
Automatic shutdown (30 minutes).

Different methods for measurement:

Immersion: You can analyze the sample in a beaker.
Sampling: Use it as a shovel to analyze the water.
Drops: LAQUAtwin meters can measure sample volumes as small as 0.05 ml by placing a drop of the sample onto the sensor using a pipette.
Solid samples: Foods containing some moisture can be analysed by placing a small piece directly onto the sensor.
Powders: Simply place the powder sample onto the sensor and pour the defined volume of deionised water over it.
Paper and textiles: If you wish to analyse sheets of paper and textiles, cut the sample into small pieces and place them directly onto the sensor. Pour the defined volume of deionised water over them.

Measurement in three easy steps:

. Calibration: For a correct calibration, the sensor must be clean beforehand. If not, rinse it with water and place a little standard solution on the sensor and press the calibration button. A smiley face will appear indicating that the calibration is complete. Clean the sensor with water until the calibration solution is removed and dry it with a soft, clean tissue.

. Analysis: Only a tiny amount of sample is needed, so just fill the sensor and wait a few seconds until the smiley face appears.

. Cleaning: Always keep the sensor clean.

Sensors should be replaced after approximately 1500 measurements or when calibration cannot be performed. Sensors are sold separately and can be easily removed and replaced.
