This pocket sized waterproof meter is the best portable pH meter we have found available on the market. Use in the lab or in the field. Built-in sensor allows you take measurements two ways, by immersing meter tip in sample or by placing a small amount of your sample directly onto the sensor.

Horiba LAQUA Twin pH Meter (pH 22)

 

Main Features:

  • Waterproof
  • Uses samples as small as 150 µL
  • Easy 3-point auto-calibration
  • Automatic range selection
  • Slope adjustment
  • Length 6 1/2"
  • Weighs only 2oz
  • Includes: hard carrying case, batteries, 14ml bottles of 7.01 & 4.01 pH calibration solutions, deionized water

This meter is portable and can be used anywhere. It takes highly accurate pH readings and requires only a small amount of sample solution. Very useful not just for agricultural purposes, but anywhere that an alkaline or acidity value of a liquid is needed. Simply immerse tip in sample or place a small amount of your sample directly on the ion selective membrane and the pH results are instantly displayed on the convenient 3-1/2-digit LCD.

The glass electrode sensor is protected by a sliding guard. The cartridge-type sensor is easy to remove to replace if needed.  Powered by 2 CR2032 lithium batteries, it has an automatic shut-off feature and an easy to read LCD scale. Measures from pH 2 to pH 12 with an accuracy of 0.1 pH. Instructions are included.

 

Use to measure:

  • Soil pH
  • Plant leaf sap
  • Urine & saliva
  • Foliar and hydroponic fertilizers
  • Rain & drinking water
  • Juices & milk

LAQUA Twin pH Anatomy

1. Sensor guard protects the electrode. The delicate flat sensor is protected by a sensor guard to ensure safety during use. To perform scoop measurement, just slide back the lid.

2. The replaceable sensor prolongs useful life
Cartridge-type sensors are simple to replace.

3. CAL button simplifies standardization
Takes all the fuss out of reference calibrations. The LAQUA Twin automatically makes the calibration with just a push of this button.

4. Auto shutoff saves batteries
If you forget to turn off the LAQUA Twin, after 60 minutes of non-use, the Auto-ShutOff circuit automatically turns it off for you.

Digital Display:

1. pH Readout
Measured pH values are shown to 1/100 pH; calibration values to 1/100. (Readout blinks when pH values is below 0 or above 14 pH.)

2. Battery warning
Alerts you to low battery.

3. Temperature warning
The "°C" blinks when the temperature exceeds the range 0 - 40°C

4. Calibration indicator
Lights up during reference calibration.

5. Stable-readout indicator
Lights up when readout has stabilized.


 

Using the pH Meter

Even if you drop it in the water, there is nothing to fear. Its waterproof structure makes the LAQUA ideal for carefree outdoor use and expands in one stroke the scope of pH measurement activities.
*impervious to water for 30 minutes up to a depth of 1 meter. Proper function is not assured if immersed deeper than 1 meter

With Sliding Lid Open

Immersion measurement
To take measurement of water quality in rivers or lakes, just immerse the sensor in the water and note the measurement results.

Scoop measurement
For hard to reach places, just immerse the sensor in the solution and the sensor guard will scoop up a sample. Lay the LAQUA Twin flat to measure

With Sliding Lid Closed

To measure solids or powders
Just place the sample directly on the sensor. Before measuring earth, powder, and other solid samples with low moisture content, add a drop or two of deionized water.


To measure in drops
Use a eye-dropper to drop about 0.1 mL of the sample solution on the sensor.

To measure rigid surfaces
To measure surface pH, wipe the surface of the sample with a sampling sheet dampened with deionized water and place the sheet on the sensor.
