Horiba LAQUAtwin Mobile Precision for Water Treatment
The compact Horiba LAQUAtwin pocket testers deliver fast, accurate and user‑friendly on‑site measurement of key water parameters—directly from a single droplet. In the HeylNeomeris online shop, you’ll find carefully selected models designed for professional use in water treatment, environmental analysis, aquaculture, and laboratory routines.

Why LAQUAtwin Devices Excel in Water Treatment:

  • Ultra‑low sample volume: only 0.05 mL per measurement
  • Rapid results: ideal for mobile checks and spot analyses
  • Laboratory‑grade accuracy in a pocket‑sized instrument
  • Effortless operation: no special training required
  • IP67‑rated housing: waterproof, dustproof, and rugged for field use

Key Applications in Water Treatment:

  • Quick screening in drinking water testing or process water quality control
  • Routine monitoring of parameters such as pH, conductivity, calcium, sodium, or nitrate
  • Interim checks in laboratories or treatment plants where bench‑top instruments aren’t practical
  • Perfect for service technicians, field engineers, and operators of small‑scale systems

Sample Models Available in the HeylNeomeris Shop:

  • Horiba LAQUAtwin pH‑11 – precision pH measurement
  • Horiba LAQUAtwin EC‑33 – conductivity monitoring
  • Horiba LAQUAtwinNa‑11, Ca‑11, NO₃‑11 – targeted ion analysis for sodium, calcium, and nitrate
