Digital CO2 Carbon Dioxide IAQ Monitor Controller with Relay Function Cable NDIR Sensing Probe for Greenhouse Home Office Factory 4.5m

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 【Smart Control】This controller has a built-in light sensor that overrides the CO2 control and turns off the CO2 device when it senses darkness. Helps monitor and control CO2 values in greenhouses and homes. 【Control CO2 Generator】Minimum and maximum CO2 level. In plant mode, power is supplied to the CO2 generator or regulator via the output socket when a minimum level is sensed. When the maximum level is reached, the power will be turned off. In human mode, it's the opposite. 【Altitude Adjustable】The monitor can be used at different altitudes. You can adjust the current altitude to get the most accurate value. 【Expandable Sensing Probe】Display CO2 chart with adjustable time scale (week/day/hour/minute/auto). The sensing probe cable has a length of 4.5 meters and can extend the measurement spot up to 4.5 meters from the display. 【High Accuracy】Accurate 2-channel low-drift NDIR CO2 measurement, programmable CO2 control value and zone value allows you to set the required CO2 level for different plants. This 7530 wall-mount CO2 controller comes with an external CO2 sensing probe that helps you measure CO2 levels in enclosed spaces. It can be used for indoor air quality CO2 monitoring and greenhouse CO2 measurement. It can also be used and operated in other work spaces, such as offices, hospitals, schools, stations, residences, commercial buildings, or home use. It can also be used to control other connected equipment, such as CO2 generators and ventilation fans, and is easily controlled with two modes (Plant OR Human mode) that disable control for low and high CO2 concentrations. The 7530 provides a simple and affordable way to control and monitor CO2 levels in greenhouses, homes, hydroponics, mushroom farms, commercial buildings, and more. Features: Accurate 2-channel low-drift NDIR CO2 measurement Comes with 4.5M external CO2 sensor for use in closed spaces Displays real-time CO2 values Displays CO2 charts with adjustable timescales (weeks/days/hours/minutes/auto) Auto max. /min. Recall on CO2 chart Programmable CO2 to control output power on/off Zone value and CO2 center value Audible alarm to warn of CO2 concentration Target zone indicator on CO2 chart Built-in day/night automatic detection of CO2 probe to override CO2 control Backlight to assist in dark operation Directly powered by AC100~240 VAC Sensing probe cable length is 4.5 meters, allowing the measurement spot to be 4.5 meters away from the display. Install a 3kA@300VAC fuse on the meter to avoid damage due to power overload.
