Handheld CO2 Detector 400-5000ppm Carbon Dioxide Meter Air Quality Monitor Temperature Humidity Sensor with Alarm

DescriptionDue to transportation regulations, batteries are not included in the shipment.Thank you for your support.Warm TipsThis device has a measurement range of 400–5000 ppm. If the CO2 concentration exceeds 5000 ppm, "H1" will be displayed along with a continuous beeping sound. To resume measurement, please turn off the device and restart it.Model S8601 uses a semiconductor sensor, while S8601A features an infrared sensor. Infrared sensors offer greater sensitivity and accuracy.SummaryThe S8601/S8601A CO2 Detector is equipped with a high-precision carbon dioxide sensor and also monitors ambient temperature and humidity. It is widely applicable in agriculture, industrial safety, and everyday environments.It helps improve air quality, prevent the spread of infectious diseases, and enhance public health and safety.FeaturesCO2 concentration measurementTemperature unit switch: °C/°FMeasurement hold functionDual-line LCD display showing CO2 levels and temperatureBacklight color indicator: green/yellow/redAuto power-off functionFAQsQ1: Can this CO₂ detector be used in greenhouses or agricultural environments?A1: Yes, both S8601 and S8601A models are suitable for use in greenhouses, plant nurseries, and other agricultural settings to monitor air quality and optimize plant growth conditions.Q2: Does the device need calibration before use?A2: No calibration is required before initial use. The device comes factory-calibrated. However, for long-term accuracy, it's recommended to place the unit in a well-ventilated area periodically for self-calibration.
