Product Number: E41M010
The Radiometer ISE21Na-9 Sodium Ion Selective Electrode (ISE) has a glass body, a non-refillable internal electrolyte, and sodium ion (Na+) specific glass sensor. The ISE21Na-9 is a half-cell ISE and requires an external reference. The Radiometer REF251 (article no. E21M001) or REF451 (article no. E21M005) reference electrode is recommended. This ISE is a screw cap electrode and requires the CL114 cable (part no. A94L114) for compatibilty with Hach sensION+ benchtop meters (or any ion meter with a BNC connection).
To meet your analysis needs, the Radiometer Analytical ion selective electrode range offers high quality sensors for a variety of ionic species in solution.
Each Radiometer Analytical Ion Selective Electrode is carefully controlled in production. Each ISE is delivered with an individual control report including information on the response curve, checkpoint value, and slope.
