Meter Specifications

Horiba LaquaTwin Range

Flat sensor

Employing the same test principle as standard laboratory electrodes, the LAQUAtwin packs all components into a flat sensor that is less than 1mm thick. Tests liquids in trace volumes, and can also be used for solids, powders, and paper/materials (containing moisture)

B-711/712/713 (pH) incorporates a glass membrane and a reference electrode. B-771 (conductivity) incorporates an electrical conductivity cell. Ion meters and the sodium salt meter incorporate an ion membrane and reference electrode.

B-771 (conductivity) does not work with solids, powders or paper/materials.

Ion Electrode

The LAQUAtwin ion electrode is an ion-selective electrode that produces an electric potential according to the concentration of the specific ion in solution. Results are produced very quickly and correlate closely to ion chromatography measurements, the gold standard analytical method.

Parts & Function

Nitrogen Only compact meter for a quick and reliable measurement of nitrate ion at the scene.* Special application packages for crop (B-741) and soil (B-742) are also available. Applications include: Soil testing; food quality control; cultivation management; food quality control; growth management of crops.
Potassium Only compact meter for a quick and reliable measurement of potassium ion at the scene using ion selective membrane. Applications include: Soil testing; food quality control; cultivation management; health management
Calcium Only compact meter for a quick and reliable measurement of ionized calcium at the scene using ion selective membrane. Applications include: Soil testing; food quality control; cultivation management; health management; food quality control; breeding water of coral; water hardness measurement
Sodium Only compact meter for a quick and reliable measurement of sodium ion at the scene using ion selective membrane. Applications include: Health management; food quality control; environmental measurement; salt water damage testing.
Salt Only compact meter to measure sodium ion to calculate into NaCl based salt concentration unlike the conductivity converted meters. Applications include: Health management; food quality control; dietary instruction
pH Accurate pH measurements in a few seconds, from a single drop. 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; 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.
E.C. Determine water conductivity with as little as 0.12 mL of sample. 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.
