HORIBA handheld meters and pocket testers
Versatile for the determination of quality parameters in liquids
The LAQUA series of the Japanese manufacturer HORIBA comprises an extensive range of hand-held measuring instruments in various designs and for diverse applications, e.g. in research, agriculture, public institutions and industry.
In addition to the classic benchtop instruments for laboratory analyses, e.g. for pH, ORP (redox), conductivity and TDS (dissolved solids), the manufacturer convinces with handy, easy and intuitive to use devices / pocket testers for manual applications, e.g. directly at the water body or in the grain field.
The handheld testers from Horiba have a large display, keypad and up to 3 connections for the various electrodes and sensors suitable for the application, for example the LAQUA WQ-330 model for measuring pH, conductivity and dissolved oxygen in surface waters.
Pocket testers are a particularly popular product with many users. The handheld testers must be compact, easy to operate and have a sufficiently large and easy-to-read display. The sensor technology should be robust and reliably calibratable, measure sufficiently accurately and be easy to clean. All these requirements are fulfilled by the water-proofed HORIBA pocket testers / handheld meters, among others also by the innovative haptics and optical/color design. The testers are used very successfully for pH, conductivity, salinity, sodium ions, potassium ions, nitrate and calcium ions in the measuring ranges adapted to the application case.
HEYL NEOMERIS cooperates very closely with HORIBA as a sales partner, offering expert advice and enabling customers to HeylNeomeris.shop and the portal Horiba - Pocket Tester Shop, to obtain further detailed information on the hand testers and to select products from the Horiba product portfolio and order them directly online.
Application areas and examples
Exemplary for the worldwide use of the measuring devices are the following applications:
Agriculture and plant breeding
- Measuring dissolved oxygen in greenhouse crops to prevent growth problems.
- Checking nitrogen and potassium content in sap of crops such as vegetables
- Nitrate measurement in turfgrass as an indicator of soil nitrogen availability
- Rapid measurement of potassium in dry plant tissue or fresh petiole sap
- Fresh root sap analysis as a quick solution for determining nitrogen status in bulbous plants
Aquarium and fish farming
- Checking pH, conductivity and salinity in freshwater and saltwater aquariums
- Measurement of critical water parameters, such as calcium, magnesium, phosphate, ammonium, etc.
Beverages and food
- Checking the quality parameters pH, conductivity/dissolved solids (TDS), dissolved oxygen, sodium, potassium and calcium in the process of brewing beer.
- Quick and easy measurement of calcium content in milk and dairy beverages
- Checking the residual sodium content in the CIP process with alkaline cleaning solution (NaOH)
- Determination of sodium and salt content in food samples
- pH measurement of vegetables and fruits, pickled for preservation in oil, vinegar etc.
Water, drinking and process water
- Evaluation of surface water quality by measuring pH, conductivity, dissolved oxygen and temperature
- Measurement of salinity in natural waters for ecosystem assessment
- Calcium determination in drinking water for water hardness assessment
- Measurement of the parameters pH, conductivity, redox (ORP), dissolved substances (TDS), dissolved oxygen in water samples from cooling towers, boiler plants, etc.
