The CHHC-4 Total Environmental Controller has the same button controls, layout and design as its predecessor, the CHHC-1, but we've made some drastic improvements! We've added plant friendly green LED displays to avoid plant cycle disruption. We've introduced weather resistant housing to avoid controller contamination. We have installed a removable remote probe assembly for easy product placement and probe replacement. We have added a dual beam CO2 sensor - the highest tech, most accurate sensor available to the hobby hydroponics industry. Most importantly, we have incorporated ROHS compliant construction to reduce the use of hazardous materials in the construction of Sentinel products. It is our mission to produce high quality, reliable products while remaining environmentally responsible. The CHHC-4 accomplishes that and so much more!
