In order to reduce normal contamination coming from industrial use, this electrode combines a polymer reference and double junction technology. With this technology, no refilling is required and the electrode can be used in samples such as organic compounds, proteins and heavy metals. In addition, the pH electrode uses a unique annular PTFE junction that minimizes clogging.
Some models also feature a built-in amplifier, which allows for measurements to be taken far from the location of the instrument without requiring a transmitter. HI1003 probes incorporate a BNC connector that enables connection to any pH meter quickly and easily. Models with 3 or 5 meters (9.8 or 16 feet) cable are available.
