pH Meter

Accurate pH measurements in a few seconds, from asingle drop. Water pH varies in different environments, and a slight change can often have a major effect. Whether you need to keep the pH of an aquarium within tight limits, are checking for the acidity of rain water or for the quality of meat and fish products, LAQUAtwin compact pH meters are ideal for you. No matter where and when you need to test.

Applications include:

Fresh water testing (rain, rivers, lakes, hot springs); aquaria; drainage treatment solutions; soil testing for improved agriculture; fermentation and brewing; food freshness testing; research laboratories; QC of  medical supplies and cosmetics; preventative dentistry; school education, etc.


Determine water conductivity with as little as 0.12 mL of sample. The conductivity of rain water is a trusted guide to determining atmospheric purity. In agriculture, measuring the conductivity of soil allows farmers and agronomists to determine optimum fertilizer usage and check the ‘health’ of soil after salt water damage. The LAQUAtwin meter makes conductivity testing simple, anywhere.

Applications include:

Fresh water testing (rain, rivers, lakes, hot springs); aquaria; soil testing for improved agriculture and analysis of salt water damage; analysis of surface cleanliness prior to coating; and improved paint adhesion.

Ions and Salt

Measure ion content with just 0.3 mL of sample. The correct concentrations of salt, together with nitrate, calcium, potassium and sodium ions are essential to the health of all living things. The LAQUAtwin range of compact meters provides accurate measurements of these parameters from the smallest of samples.

Applications include:

Soil and sap testing for improved agriculture; food testing
