The LAQUA Twin series from Spectrum Technologies gives you laboratory-level precision directly in your hand. These professional, handheld measuring instruments are developed for fast and accurate measurements in water, nutrient solutions, soil, and plant sap, and are widely used by greenkeepers, gardeners, and professionals in plant cultivation and care.
The instruments are compact, waterproof (IP67), and easy to use in the field. The unique flat sensor makes it possible to measure extremely small sample volumes — down to just 0.3 ml — without the need for beakers. The sensors are stored dry, and the measurement results correlate closely with traditional laboratory analyses.
The LAQUA Twin series is available in several versions, allowing you to measure exactly the parameter you need:
-
pH
-
Electrical Conductivity (EC)
-
Potassium (K⁺)
-
Calcium (Ca²⁺)
-
Sodium (Na⁺)
-
Nitrate (NO₃⁻)
All models feature automatic temperature compensation, digital calibration, a clear LCD display, and automatic power-off. The instruments are supplied complete with batteries, a storage case, and calibration standards. The sensor can be replaced after approximately 1,500 measurements, without the need to replace the entire instrument.
