The EDT directION 4001 Reference Electrode is designed for use with the ISE flowcells for Nitrate, Ammonium, Chloride, Potassium and Calcium. This electrode has a 2.3mm bore and is not suitable for use with the Fluoride flowcell which requires Cat Number 4001/1.2.

The Reference cell is slotted into the 2 or 3 place flowcell holder with an ISE to make a working electrode system. It incorporates an Ag/AgCl reference refillable at the top of the cell by peeling back the label and revealing the fill hole.

Connection to the Ion Meter is made via a 1mm pin at the top of the electrode next to the fill hole. When configuring the flowcell holder it is important that the reference electrode is upstream. i.e. the first to come into contact with the standard and sample flow. This will ensure good integrity of contact between the cells. 

The reference junction is of porous Teflon and is resistant to blockage.

The reference is already supplied filled with Saturated KCl/AgCl filling solution and it is normal for some of the KCL to remain un-dissolved. This will not detract from the performance of the system.

For a complete system you will require a reference and ISE flowcell, a holder, a combination cable to a BNC connector and an Ion meter EDT model DR359TX.

Tubing and pump not supplied.
