These devices incorporate a flat ion electrode for microvolume measurement. The replaceable electrode uses the same measurement principle as the traditional nitrate ion selective electrode (ISE). They only require a few drops (0.3 ml) to provide a fast and accurate analysis.

It can be used as a traditional nitrate meter by immersing the electrode in a liquid.
An absorbent paper allows us to analyze micro samples from 50 µl.

Main features:

Temperature compensation.
Automatic calibration: recognizes calibration solutions. The user can choose calibrations at one or two points.
Detection of result stability.
Waterproof (IP67).
They do not use reagents.
Automatic selection of the appropriate range.
Automatic shut-off (30 minutes).

Different methods for measurement:

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

Measurement in three easy steps:

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

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

3. 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.
