ION SELECTIVE ELECTRODES
Do you measure Ammonium, Calcium, Chloride, Fluoride or Nitrate in water?Have you used conventional Ion selective electrodes?
If the answer to any of these questions is yes, then direct ION electrodes are just what you've been looking for!
Main features and benefits include: No reference electrode needed
No filling solution
Fully submersible and waterproof
Virtually unbreakable
Solid state sensors
Colour coded caps for identification in the field
Can be left dry for long periods
Ideal for unskilled operatives
Long lifetime
Product Description
direct ION electrodes are rugged solid state sensors with built in reference elements that do not require any filling solution or maintenance.
Fully Submersible
direct ION electrodes are waterproof and submersible. This gives the field operative the ability to cast the probe into the water from awkward sample points, bridges, banks and boats.
Cable length can be stipulated at the time of ordering. Maximum length is 10 metres. Standard products are fitted with 1 metre of cable terminated with a BNC connector.
Laboratory or field use
Though direct ION electrodes have a rugged and waterproof construction, there has been no compromise on technical specification (see table below). Standard Ion selective performance is surpassed under both laboratory and field conditions.
What meter can I use?
direct ION electrodes can be used with any conventional laboratory or hand held pH meter with a millivolt display mode. Please stipulate the connector required on your order.
