Series Description

The Greystone GH Series greenhouse/horticulture sensor is designed for a greenhouse or indoor grow facility to monitor and allow control for optimum plant-growing conditions. The GH Series is available in two models: temperature & humidity or temperature, humidity, & carbon dioxide. The GH Series utilizes a highly accurate and reliable dual-channel, non-dispersive infrared (NDIR) sensor to monitor CO2, a precision thermistor to monitor temperature, and a thermoset polymer-based capacitance sensor to measure humidity levels. All sensors are encapsulated in filtered sensor pods that are field replaceable. Features include an LCD for configuration and visual indication, various output signal types, and optional relays for alarm indication. An IP65-rated enclosure, that can be either wall-mounted or suspended from the ceiling, is provided to protect against moisture penetration.
