Horiba LAQUAtwin 4EC-33 Conductivity Tester – Successor model to the EC-33

Horiba LAQUAtwin Conductivity Tester with 4 calibration points (4EC-33)

Find out more about the accuracy of the new successor models to the HORIBA pocket conductivity testers: Your ideal choice for precise conductivity measurements. Manufactured in Japan, the 4EC-11, 4EC-22 and 4EC-33 models represent the highest quality among pocket testers. They offer numerous benefits for users in laboratories, industry, aquaculture, water treatment, schools and universities, as well as for amateur gardeners.

An overview of the new HORIBA Pocket Conductivity Tester series:

Model 4EC-11:

Water resistance, the ability to analyse very small samples from 0.12 ml, 3 calibration points and a conductivity measurement range of up to 19.9 mS/cm are the key features of these instruments. They are easy to operate and maintain, ensuring long-term reliability.

Model 4EC-22:

In addition to the features of the Model 4EC-11, this model offers a temperature display, four calibration points and an extended conductivity measurement range of up to 199.9 mS/cm. This instrument is ideal for demanding applications where the medium temperature must be recorded for detailed analysis.

Model 4EC-33:

With the widest measurement range, the ability to measure TDS and additional functions, this model sets new standards. It is designed for professionals who need to carry out highly precise measurements under varying conditions.

Applications and benefits for the user:

‘Immersion’:

Direct measurement is possible in solutions. For example, you can immerse the tester in a beaker and determine the value.

‘Scoop’:

The hinged lid, which acts as a scoop here, allows you to easily take a sample from a hard-to-reach area.

‘Drops’:

Efficient analysis of the smallest volumes.

Thanks to their user-friendliness, durability and ‘Made in Japan’ quality, HORIBA pocket conductivity testers are a reliable solution for a wide range of measurement applications.

LAQUAtwin 4EC-33: The pocket-sized conductivity and TDS meter

The only portable meter that measures conductivity and total dissolved solids (TDS) directly in a 0.12 ml sample. You do not need a beaker to calibrate your meter or measure a sample. Simply place a few drops of the standard solution or sample onto the sensor. This method saves you time and prevents the wastage of your valuable sample.

Your pocket-sized laboratory – practical for on-site use: Ideal for water quality testing in aquariums, food, beekeeping (honey) and many other applications

HORIBA’s unique and compact meter combines an electrode, display and sample chamber. This enables simple and effective measurements directly on site, as the measurement is taken with just a single drop.

Note:

How can I tell if I have an old or new device?

If your Pocket Tester is marked ‘4-cell’, you have the latest version of this device. In this case, you will need the replacement sensors listed in the cross-selling section, as well as the standard and conditioning solutions. These have been specially optimised for the new Pocket Testers and are not suitable for older models.
