Collection: 4-Series
The 4-series, also referred to as the A-Series by some manufacturers, is a 20mm diameter compact sensor format with either 2, 3 or 4-pin confguration depending upon the application.
Frequently used in portable instruments, the 4-series package balances performance with size and is the most commonly used electrochemical sensor package globally.
The DDS 4-series sensor range includes dual-toxic and both lead and lead-free O2 sensors among almost 40 models, with more being added frequently.
