4M LAQUAtwin kit Ionometer Case

Key Features:

Temperature compensation.
Automatic calibration: Recognizes calibration solutions. User can choose one- or two-point calibrations.
Result stability detection.
Waterproof (IP67).
No reagents used.
Automatic selection of appropriate range.
Auto power off (30 minutes).

Different methods for measurement:

Immersion: You can analyze the sample in a beaker.
Sampling: Use it as a scoop to analyze 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 fabric: If you want to analyse sheets of paper and fabric, cut the sample into small pieces and place it directly on the sensor. Pour the defined volume of deionised water over it.

Measurement in three easy steps:

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

2. Analysis: Only a tiny amount of sample is required, so it is only necessary to 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 is no longer possible. Sensors are sold separately and can be easily removed and replaced.
