For determining the amount of dissolved oxygen (using the Clark principle) or carbon dioxide (using the Severinghaus principle) in water: regardless of colouring, turbidity and flow rate.
3- Conductivity measuring cells
Conductive two- or four-electrode cells for measuring the electrolytic conductivity of the solution (the salt content).
2-electrode conductivity cell
4-electrode conductivity cell
4- PH measuring systems
Vista Mehr Negar PH Measuring Equipment products,are PRONOVA and Stelzner journalist for portable and handheld usability to be useful in labratoary and environment.
PH AGARA 2000
for measuring pH either directly on-site in the soil or in the lab to form of portable
The manual system can be directly used for the measurement of pH and temperature. Lightness and portability makes its application useful in the measurement of pH and temperature of small objects. Operating temperature is up to 50 ° C.
The pH/T pocket tester is designed for taking simple and speedy pH measurements in liquids and features automatic temperature compensation. The tester is housed in a waterproof enclosure and features a double display and battery-charge meter (so you can avoid taking bad measurements with a weak battery). The tester also enables electrodes to be swapped in seconds. Additional features include a stability indicator for reading measured values, automatic shut-off, automatic calibration (single or double point), and a HOLD function for freezing measured values.
Pocket system is very cheap for quick measurements.
Additional information see the product catalog .
5- Portable liquid measurements
These measuring devices offer the advantages of a mobile field unit together with the precision and comfort of a laboratory instrument: with high measurement accuracy, a multifunction graphic display, integrated data logger and heavy-duty IP65 housing. The important GLP functions – such as date/time, primary measured value, secondary measured value (including the physical units), tem- perature and device number – are transmitted and recorded in the data file.
Measures pH, redox, ion concentrations, conductivity and dissolved gases.
6- Stationary liquid measurements (Indoor & Outdoor)
Single-channel measuring transducer
The MV 50XX series of measuring transducers is perfect for taking stationary measurements directly at the measuring point in the open field. The measuring transducer is simple and intuitive to use. It also maintains the essential functionality with maximum operational reliability and safety. Each MV 50XX features a large OLED display and plain-text menu navigation. The software also enables you to configure, calibrate, view and record measured values at your PC using a standard USB port.
Areas of use:
- Water treatment
- Water-quality monitoring systems
- Process monitoring
- Process control
- Cost-effective measurement of process
- Easy to use (plain text menus)
- Simultaneous temperature measurements and
