Sentinel Fuzzy Logic CO2 PPM Controller CPPM-4i

The CPPM-4i features Sentinel Intelligent CO2 Enrichment (S.I.C.E.) which allows interfaced CO2 enrichment with Sentinel ICG series generators for unparalleled control (Patents Pending).

The Sentinel True Fuzzy Logic gives the most precise compressed CO2 regulator enrichment available. The large, pixelated LCD display makes user programming intuitive and simplified.

The Time Clock control provides greater user flexibility and control vs. older photocell models. The Remote Sensor is 15 ft (5m) expandable up to 160 ft (50m) which accommodates a wider range of growing environments. The RoHS compliant construction is environmentally friendly.
