pH electrode

COMBINATION pH ELECTRODE  EPX 4 & EPX 4U
The   combination   glass   electrodes  EPX 4   and   EPX 4U are used for pH measurements in cooperation with pH meters equipped with BNC connector they
may be also used for continuous measurements in flow in pipelines with use of, offered by us, GXP 2t flow head.
The EPX 4U model may be used for  measurements in deionised, pure and
ultra pure water. Teflon junction limits the penetration of the measured solution
into the electrode and ensures a good contact with the measured sample what
results in accurate and stable measurements even in ultra pure water. There is no
need to add anything to the samples to obtain stable readout of the results.  
The EPX 4  model is designed for measurements in liquids containing strong
acids or alkalis, may be used in chemical wastes.
The electrodes may work in liquids with temperatures up to 90°C.
The measuring membrane is a round glass bulb. Electrolyte is in a gel form and it
is not refillable. Standard length of the cable is 1m.
In case of using the electrode with our industrial meters and controllers it is connected with use of a cable with a pre-amplifier in case of work with meters of 801 or 804 series. In case of pH meter CP 421 the pre-amplifier needs to be used in case of 10m or greater distance between the electrode and the meter.
