Measuring pH levels is a crucial part of production control processes in various industries, from laboratories to agriculture, food production, and even high-tech products. When fast and accurate measurements are needed without access to a full laboratory, Horiba LAQUAtwin pocket pH testers are the ideal solution. These compact and easy-to-use meters offer high-quality results with just a few drops of sample using an innovative electrode. But how do you choose between the three available models – pH-11, pH-22, and pH-33? In this blog, we’ll explore the differences between these models and help you decide which is best suited for your needs.
What are LAQUAtwin Pocket pH Testers?
Pocket pH testers are portable, waterproof instruments equipped with a unique flat potassium chloride gel sensor technology, providing accurate results with very small sample volumes – starting from just 0.05 ml. They can be used for a wide range of applications – from measuring the pH of liquids, viscous substances, and solids, to powders and even textile materials.
The tester consists of two parts: a measuring device and a replaceable sensor.
pH-11 – Simplicity and Basic Functions
The LAQUAtwin pH-11 is ideal for those seeking an easy-to-use but reliable pH tester. It offers up to 2 calibration points and can measure a pH range from 0.0 to 14.0 with an accuracy of 0.1 pH units. This model is suitable for users who don’t need extremely high precision or complex measurements but still require fast and accurate results.
Who is pH-11 for?
This meter is a great option for students, hobbyists, or simple lab tasks where precision is important but high resolution isn’t necessary.
Also well-suited for everyday measurements in gardening or water quality checks where specific calibration is not required.
pH-22 – More Precision and Additional Features
If you need higher accuracy and flexibility, then the Horiba LAQUAtwin pH-22 is the right choice. It offers up to 3 calibration points, enabling more accurate results. Additionally, this model can measure both pH and ORP (mV), making it a more versatile instrument. With improved accuracy down to 0.01 pH units, it’s more suitable for professional use.
Who is pH-22 for?
Ideally suited for scientific research where greater accuracy and more complex measurements are required.
It delivers excellent results in the food industry and agriculture, where precise data is crucial to ensure product quality and proper fertilization planning.
Recommended for those who need to regularly test soil or water with higher precision.
pH-33 – The Professional Choice with Maximum Functionality
The highest-end model is the Horiba LAQUAtwin pH-33. It offers all the features of the previous models, with even greater flexibility and precision. With up to 5 calibration points and the added ability to measure temperature, the pH-33 provides the most accurate and reliable results. It is designed for professionals who need very precise and complex measurements, as well as users who work with various samples in challenging conditions.
Who is pH-33 for?
Scientific laboratories, where the highest precision and functionality are essential.
Manufacturing or research institutions where complex measurements, including temperature correction, are necessary.
An excellent choice for environmental monitoring, such as simultaneous pH and temperature measurement of rivers, lakes, and other bodies of water.
When choosing between the pH-11, pH-22, and pH-33 models, it’s important to consider your specific needs. Depending on the complexity of your measurements and your particular working conditions, Horiba offers a pH meter that will meet your requirements!
The testers come with a wide range of calibration solutions: pH1.68, pH4.01, pH6.86, pH7.00, pH9.18, pH10.01, and pH12.46, allowing you to select calibration options as close as possible to your target range to ensure accurate measurement results.
A demo unit of the pH-33 will soon be available for testing in your environment and for demonstrations – feel free to inquire and schedule a demo at your facility.
Stay tuned for the latest updates on HORIBA LAQUAtwin testers and their capabilities. The next tester to be introduced will be the LAQUAtwin nitrate tester, with a demo unit available soon.
