GLASS BODY BULB ELECTRODE – FLS pH/ORP 400
The FLS 400 line of pH/ORP electrodes with glass body has been designed for fitting a wide range of applications. The ceramic junction guarantees high performances in terms of pressure and temperature. Different types of ceramic junction allow finding the proper solution in according with application needs: annular for a faster response time, 3-diaphragmfor higher pressure rate. Moreover the standard double junction prevents the contamination of reference solution granting a long operating time. Version with long outline cable (9 mt) or with head connection
