ATMOS-B1 is a simple solution to controlling temperature and humidity inside the growing area. ATMOS-B1 is the first basic atmosphere controller that maintains a perfect balance between cost and accuracy.

ATMOS-B1 pairs a precision solid-state temperature and humidity sensor with a reliably engineered circuit board. The user selects desired temperature, humidity, and appropriate mode of operation for the unit. Once simple set-up is complete just plug in external equipment such as fans, dehumidifiers and CO2 equipment and ATMOS-B1 does the rest.

• ATMOS-B1 controls a cooling device such as a fan.
• ATMOS-B1 controls a dehumidifier OR a humidifier. (user selectable)
• ATMOS-B1 has a built-in photocell that can activate a CO2 device during the day. Can be coordinated with the exhaust fans.
• Offers multiple modes of operation (user selectable)

A 15-amp circuit breaker and heavy-duty internal construction ensures that the unit will operate for years without fail. We only use high-quality UL / CE listed components.
