Calcium ion sensor
Wireless calcium ion sensor for water and solutions, for assessing water hardness and investigating soil liming in practical lessons.
The sensor measures the calcium ion content in samples and transmits the readings wirelessly to a digital laboratory. It supports six experiments: determining the hardness of natural waters, monitoring calcium in drinking and mineral water, assessing the need for soil liming using extracts, studying calcium fertilizers and nutrient solutions, monitoring the concentration of Ca²⁺ during precipitation, dilution and ion exchange, plotting calibration curves. Suitable for practical work in chemistry and ecology.
- Determination of calcium ion content in natural waters and assessment of water hardness.
- Monitoring calcium concentration in drinking and mineral water.
- Analysis of soil extracts for the content of exchangeable calcium and assessment of soil need for liming.
- Investigating calcium fertilisers, compound fertilisers and plant nutrient solutions.
- Observation of changes in Ca²⁺ concentration during precipitation, dilution and ion exchange.
- Plotting calibration curves for calcium ion activity in solutions.
