Compact Pocket Water Quality Meters LAQUAtwin
Horiba introduces the LAQUAtwin compact water quality meter, incorporating 60 years of water quality analyser research and manufacturing technology into a simple, pen-sized design.
Select from seven water quality parameters that suit your purpose, including pH, conductivity, various ions (Na+, K+, NO3-, Ca2+) and salinity. Bring the LAQUAtwin with you wherever and whenever you need it. It's your lab-in-the-field!
pH Meter: A pH meter is an analytical instrument used to measure the acidity or alkalinity of a liquid sample, expressed as pH. pH measures the concentration of hydrogen ions (H+) in a solution, and ranges from 0 to 1the with a pH of 7 considered neutral. pH meters are commonly used in various applications, such as water and wastewater treatment, food and beverage production, and clinical laboratories. In water treatment, pH meters are used to monitor the pH of water sources, such as drinking water, wastewater, or process water, to ensure that the pH is within a safe and effective range for treatment processes. In food and beverage production, pH meters are used to measure the pH of products such as beer, wine, dairy products, and sauces to ensure consistent quality and safety. In clinical laboratories, pH meters are used to measure the pH of biological fluids, such as blood, urine, or saliva, to diagnose and monitor various medical conditions.
Conductivity Meter: A conductivity meter measures the level of conductivity in solutions. Conductivity is an ability of materials (solutions, metals or gases) to pass an electric current. Conductivity is useful in determining the overall health of a natural water body. It is also a way to measure changes in wastewater procedures at water treatment plants.
Sodium Meter: A sodium meter is an analytical instrument used to measure the concentration of sodium ions in a liquid sample. Sodium meters are commonly used in water treatment plants, food processing, and clinical laboratories to monitor sodium levels in various samples.
Salt Meter: A salt meter is an analytical instrument used to measure the concentration of salt in a liquid sample, often in aqueous solutions. Salt meters work by measuring the electrical conductivity of a solution, which is directly proportional to the concentration of ions in the solution, including salt ions (sodium chloride). Salt meters are commonly used in various applications, such as food and beverage production, water treatment, and environmental monitoring, where the salt content is an important parameter to monitor.
Potassium Meter: A potassium meter is an analytical instrument used to measure the concentration of potassium ions in a liquid sample. Like a calcium or sodium meter, a potassium meter operates on the principle of ion-selective electrode (ISE) technology. Potassium meters are commonly used in clinical laboratories to monitor the levels of potassium in blood and urine samples. Potassium is an important electrolyte that helps regulate many bodily functions, and abnormal potassium levels can be a sign of various medical conditions, such as kidney disease, heart failure, or diabetes. Potassium meters are also used in research, agriculture, and environmental monitoring, where potassium levels in soil, plants, or water sources may need to be measured.
Nitrate Meter: A nitrate meter is an analytical instrument used to measure the concentration of nitrate ions in a liquid sample. Nitrate meters are commonly used in agriculture, environmental monitoring, and water treatment to measure the levels of nitrate in soil, water, and wastewater. In environmental monitoring, nitrate meters are used to monitor the levels of nitrate in water sources, which can be an indicator of pollution from agricultural or industrial activities. In water treatment, nitrate meters are used to monitor the levels of nitrate in wastewater to ensure compliance with environmental regulations.
Calcium Ion Meter: A calcium ion meter is an analytical instrument used to measure the concentration of calcium ions in a liquid sample. The meter operates on the principle of ion-selective electrode (ISE) technology, which uses a specially designed electrode that responds selectively to the presence of calcium ions in the sample.

- What are five parameters for water quality?
- Many parameters can be used to assess water quality, but here are five common ones:
- pH: This measures how acidic or basic the water is essential for aquatic organisms that are sensitive to changes in pH.
- Dissolved oxygen (DO): This measures the amount of oxygen in the water, which is important for aquatic organisms that need oxygen to survive.
- Salinity: Salinity is the measure of the amount of dissolved salts in water. It is usually expressed in parts per thousand (ppt) or percentage (%). Freshwater from rivers has a salinity value of 0.5ppt or less.
- Conductivity: Conductivity is a measure of the ability of water to pass an electrical current. Because dissolved salts and other inorganic chemicals conduct electrical current, conductivity increases as salinity increases..
- Total dissolved solids (TDS): This measures the concentration of dissolved inorganic and organic substances in the water, which can affect the taste, colour, and overall quality of the water.
- What is the sample volume of water needed when using the pocket meters?
You can get an accurate reading from a single drop of sample water in just a few seconds. Incorporating the same parts as standard laboratory electrodes, the
LAQUAtwin compact meters are built with miniaturised components and a unique flat sensor chip, which is less than 1 mm thick.
- Can I test solid samples?
- Yes, you can. Foods and other solids containing some moisture can be tested by placing a small piece directly onto the sensor.
- Do you supply spares and accessories?
Yes, Thermoline can supply replacement sensors and standard solutions for all meter types.
Batteries for the pocket meters are CR2032 type and can be purchased locally.
