Our range of rugged, robust pH, conductivity, and oxygen meters are your ideal companion for routine use. You can use the instrument as a battery-powered portable meter or as a benchtop instrument in the laboratory. In addition to measuring conductivity, pH, or both, the instruments also measure Total Dissolved Solids (TDS), salinity, and temperature.
These meters are available as pH meters, conductivity meters, and combined meters.
- Large color display and smart features for easy measurement
- Two-in-one meters: mobile or benchtop use
- Robust instruments with IP67 rating
- Measure pH, dissolved oxygen (DO), ORP, conductivity, TDS, salinity, and temperature
Easy, robust, flexible: portable meters for field and laboratory use
The large color display with backlight on these meters makes reading the result easy in any light conditions. And to make sure that you can always trust your results, the meters are equipped with an integrated sensor quality check.
With one of our meters, you don’t have to worry about harsh environments or long working hours – the meters are dust- and waterproof (IP67-rated), and the powerful lithium battery provides power for hours.
If you use the meter in your lab, no problem! Simply put it on the stand plate, plug it to the power outlet, and use it as a fully functional benchtop meter.
