LAQUAtwin is a series of pocket ION meters. Using Ion Selective Electrode (ISE) technology, they are available for measuring Conductivity, Calcium, Nitrate, Potassium, Sodium, Salt concentration and pH measurement. Using just a tiny amount of sample, the LAQUAtwin proprietary flat sensors can quickly and accurately measure the values of the chemical parameters in the field.
Many foods are canned and it is important that these foods are properly and adequately acidified. Thermally processed acid foods are generally safe. However, if products are not properly acidified there can be a risk to food safety. Inadequate acidification can lead to botulism and premature expiry.
Food Standard 2.3.1 states that ‘fruits and vegetables in brine, oil, vinegar or water, other than commercially canned fruit and vegetables, must have a pH not greater that 4.6’.
In order to determine the pH level, and hence ensure the freshness of canned foodstuffs, the Horiba LAQUAtwin pH meter can be used. The Horiba LAQUAtwin pH meter is used to determine the pH of the brine (oil, vinegar, or water) used to preserve the foodstuff. This is an easy and quick method used to ensure that the brine is at the optimum pH.
The brine’s pH can be measured using the LAQUAtwin pH meter. A pipette can be used to extract a small sample of the brine solution. This is placed on the sensor of the LAQUAtwin pH meter and measured. To repeat sampling, wash the sensor with tap water and pat dry with a paper tissue.
The use of the Horiba LAQUAtwin pH meter to ensure an maximum pH of 4.6 in brine will fulfill safety requirements by preventing botulism, and thus preventing common illnesses such as gastroenteritis.
The LAQUAtwin pH meter is small and compact; convenient to carry in your pocket for easy on-site testing. Its easy-to-use interface is simple for anyone to use the LAQUAtwin hand held pH meter.

Pocket ION Meter
HORIBA’s highly-sensitive, flat sensor technology opens up new possibilities for sampling and sample types. Only a small amount of sample is required, so you can easily sample in situ without the need for beakers or other labware. Sensors are easily replaced as required.
Hassle-free automatic calibration with a few drops of standard solution reassures you of your measurement accuracy. Two-point calibration is also possible.
The meter and sensor are fully waterproof and dustproof, so you can take it anywhere.
The compact carry case contains everything you need for your measurements, including the standard solution and sampling sheets.
Only LAQUAtwin allows you to be this flexible!
Choose the best method according to your sample, your situation, and your needs.
When you're in the lab, you can test the sample in a breaker. Ensure the sensor guard sliding cap is open.
Accurate pH measurements in a few seconds, from a single 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.
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.
Only compact meter for a quick and reliable measurement of sodium ion at the scene using ion selective membrane.
Only compact meter for a quick and reliable measurement of potassium ion at the scene using ion selective membrane.
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.
Only compact meter for a quick and reliable measurement of ionized calcium at the scene using ion selective membrane.
