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.
A physiological disorder in greenhouse hydroponic sweet pepper (Capsicum annuum L.), where the base of the plant’s stem becomes swollen below the cotyledon level and wounds develop at the base of the stem’s epidermis has been named “Elephant’s Foot”.
Sodium is a mineral constantly present in soil, but an excess of it concentrated at the base of the plant stem has been shown to have a correlation with Elephant’s Foot in plants. It is necessary to analyse the conductivity of soil in which hydroponic sweet pepper is grown to consider the extent to which the stem of the plant has accumulated salt.
To determine the conductivity of the soil, the Horiba LAQUAtwin Conductivity meter can be used. This is an easy and quick method used to measure the conductivity of soil.
1. A small 5g soil sample is watered down with 20 ml of water.
2. The water and soil mixture is shaken, thus ‘washing’ the soil.
3. A small sample can be extracted via pipette
4. This is placed on the sensor of the LAQUAtwin Conductivity meter and the conductivity is measured after one minute.
5. To repeat sampling, wash the sensor with tap water and pat dry with a paper tissue
The use of the Horiba LAQUAtwin Conductivity meter to measure the conductivity of soil will improve farmers’ knowledge of the sodium accumulation and hence choose the best land to grow sweet pepper crops and avoid Elephant’s Foot disorder.
The LAQUAtwin Conductivity meter is small and compact, and convenient to carry for easy on-site testing. Its easy-to-use interface is simple for anyone to use the LAQUAtwin hand held Conductivity 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.
