SUMMARY

The HORIBA Compact Electrical Conductivity Meter LAQUAtwin EC-33B is a pocket-sized, high-precision water quality tester engineered for on-the-spot electrical conductivity (EC) and Total Dissolved Solids (TDS) conversion measurements. Requiring an ultra-micro sample volume of just 0.12 mL or more, its flat sensor technology allows you to test droplets directly without full immersion.

It is highly versatile and widely used for checking rainwater pollution, monitoring rivers and lakes, maintaining aquarium habitats, analyzing soil nutrition, and evaluating salt damage prevention in agriculture.

FEATURES

The measurement is only dropped into the plane sensor.Trace drip measurement that can be done from a plane sensor that condenses HORIBA's electrode technology.

Equipped with backlight and temperature display functionMeasurements can be checked even in dark places. It lights up when the button operation and measured values are stable.

Cost reductionStandard liquid consumption is 1/100, sample consumption is 1/100, and the sensor can also be replaced.

Don't choose a place .In addition to the compact body, it can be carried in a special case with a standard liquid bottle. The waterproof function is safe even outdoors.

A variety of measurement methods that can be selected according to the application.Drip and soak

Easy and safe measurement for anyone.With simple buttons and a safe judgment function, anyone can easily operate it.
