Product Description
LAQUAtwin Conductivity Tester – Precision Testing with Minimal Sample Volume
Easily determine water conductivity with just 0.12 mL of sample using the LAQUAtwin Conductivity Tester. Designed for a wide range of applications, this compact and reliable meter allows you to quickly assess the conductivity of various samples, from rainwater to soil, ensuring accurate results every time.
Whether you’re testing the purity of rainwater for atmospheric analysis, evaluating soil health in agriculture, or analyzing water in aquariums, the LAQUAtwin is your trusted tool for conductivity measurement. It’s also perfect for checking surface cleanliness before coating or assessing paint adhesion.
Key Features:
-
Salt/TDS Measurement for accurate water quality analysis.
-
Auto Range Change for seamless transitions between different conductivity levels.
-
Temperature Conversion with a fixed 2%/℃ adjustment for precise temperature compensation.
-
IP67 Waterproof design ensures durability in wet conditions.
-
Auto Hold function for easy reading and data retention.
-
Automatic Power Off after 15 minutes of inactivity to preserve battery life.
Applications Include:
-
Freshwater Testing (rainwater, rivers, lakes, hot springs)
-
Aquarium Water Quality Monitoring
-
Soil Testing for Agriculture & Fertilizer Optimization
-
Analysis of Saltwater Damage in Soil
-
Surface Cleanliness Checks for Coating & Paint Adhesion
