LAQUAtwin 4M Kit

3 STEPS

Easy, three-step measurement

Follow simple, good testing procedures for accurate and dependable results:

Calibrate correctly
Avoid mixing samples and standards
Always keep the sensor clean

01.Calibrate

Always ensure the sensor is clean before calibrating.
If not, clean thoroughly with water (don’t worry, LAQUAtwin meters are completely waterproof!)

Place some standard solution on the sensor and press the calibration button. Once the smiley face appears indicating that calibration is complete, wash off the standard solution with water and dry with a clean, soft tissue.

02.Test

LAQUAtwin meters only need a tiny amount of sample - so no beaker is necessary.
Fill the sensor with the sample and when the smiley face appears, the measurement is complete.

03.Clean

Clean the sensor thoroughly with water ready for the next test. When the sensor is nearing the end of its usable lifetime, it can be replaced;* you don’t need to replace the meter.

* Sensors will need to be replaced after approx.
1500 measurements or when calibration cannot be completed. Sensors are sold separately and are easily removed and replaced

1×6

One meter. Six different methods*1

Only the LAQUAtwin range allows you to be this flexible! Choose the best method according to your sample, your situation and your needs.

*1 Conductivity meters cannot be tested in solids or powders.

Immersion

When you’re in the lab, you can test the sample in a beaker. Ensure the sensor guard sliding cap is open.

Scoop

Use as a scoop to test water, for example from a river.

Drops

LAQUAtwin meters can measure sample volumes as low as 0.05 mL^*2. Place a drop of the sample onto the sensor with a pipette.

*2 Using the HORIBA sampling sheet, volumes down to 0.05 mL can be tested (except for conductivity measurements).

Solid samples

Foods containing some moisture can be tested by placing a small piece directly onto the sensor.

Powders

LAQUAtwin meters can also test dry powders.
Simply place the powder sample onto the sensor, and drop on your defined volume of pure water.

Paper and textiles

To test sheets of paper and textiles, cut up the sample into small pieces and place directly onto the sensor.
Drop on your defined volume of pure water.

UNIQUE FEATURES

Testing has never been easier!
LAQUAtwin meters have been developed using 60 years of HORIBA know-how to give you the highest quality technology that can be used anywhere and at any time. And they’re so simple to use that you won’t need any training!

ONE TOUCH

Calibrate and measure at the touch of a button — the smiley face will tell you when the result can be read.

Hassle-free automatic calibration with a few drops of standard solution reassures you of your measurement accuracy. Two-point calibration is also possible.

LAQUAtwin: the only meters with flat sensor technology.

HORIBA’s highly-sensitive, flat sensor technology opens up new possibilities for sampling and sample types. Only a small amount of sample is required, so you can easily sample in situ without the need for beakers or other labware.
Sensors are easily replaced as required.

Carry case comes as standard for handy portability.

The compact carry case contains everything you need for your measurements, including the standard solution and sampling sheets.

LAQUAtwin is IP67 rated.

The meter and sensor are fully waterproof^*3 and dustproof, so you can take it anywhere.

*3 Will withstand immersion for 30 minutes at 1 m. Not suitable for underwater use.
