Digital gas detection controller UPA3 (16 or 32 detectors)

A digital gas controller for 16 or 32 detectors

The UPA III digital gas detection controller with an excellent quality/price ratio has many advantages such as great modularity, a large LCD screen, 4 alarm levels per channel, the alarm history over the last 34 days and the possibility of inserting an 8 analog 4-20 mA input card (specific sensors) in addition to the digital inputs (or up to a total of 40 detectors).
