PH ep4
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.

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
Special features:
- Cost-effective measurement of process
:variables
- Easy to use (plain text menus)
- Simultaneous temperature measurements and
:compensation
- 2 scalable analogue outputs and 2 relay outputs
