Overview
The ST8310A Carbon Dioxide Logger is a SMART SENSOR brand device for monitoring carbon dioxide (CO2) concentration in the environment. It integrates components such as Sensor, data logging function and display screen to monitor CO2 concentration in the air in real time and record the data for subsequent analysis. The device is powered by 18650 rechargeable batteries, has a standby time of ≥ 6 hours, supports WIFI connection, and the operating language is Chinese/English.
Features
1. Multi-Parameter monitoring: measurement of carbon dioxide concentration (ppm and percentage), temperature, humidity, dewpoint temperature and wet-bulb temperature.
2. High Accuracy and resolution: CO2 measurement accuracy is +/- 50ppm +/- 3% reading, resolution up to 1ppm; temperature accuracy +/- 1 ℃/ +/- 2 ° F, resolution 0.1 ° C.
3. Large-capacity data recording: can store up to 80,000 sets of data.
4. Intelligent alarm function: support alarm value setting, with buzzer and light alarm prompt.
5. Convenient connection and display: Support WIFI connection, equipped with a display screen, and can view real-time trend charts and historical records.
6. Flexible settings: with real-time clock display, screen function, time setting and recording mode setting.
Principle
The recorder detects the CO2 concentration in the environment air in real time through the built-in CO2 Sensor. The Sensor converts the detected concentration signal into an electrical signal, which is processed and analyzed by the internal circuit, and displays the value in real time on the display screen. At the same time, the data recording function of the device will automatically store the measurement data according to the set time interval (such as 1 piece/minute set by the factory), including CO2 concentration, temperature, humidity and other related parameters, forming a historical record for inquiry and analysis. When the measurement value exceeds the alarm threshold set by the user, the device will trigger the buzzer and light to alert.
Applications
Offices, schools, hospitals, shopping malls and other indoor environments, factory workshops, chemical plants and other industrial production environments, building ventilating systems, greenhouse gas emission sources, scientific laboratories and research institutions
Steps
1. Power on: Long press the power button to start the device.
2. Settings: Set the time, recording mode (such as recording interval), alarm threshold, and select the operation language (Chinese/English) through the menu.
3. Connection: If you need to use the WIFI function, connect to the wireless network in the settings.
4. Monitoring: Place the device in the environment to be tested, and the display screen will display parameters such as carbon dioxide concentration, temperature, and humidity in real time.
5. View data: Browse stored measurement data through the history viewing function, or observe parameter changes through real-time trend charts.
6. Alarm Response: When the measurement value exceeds the set alarm value, the device will issue a sound and light alarm, and corresponding measures need to be taken according to the situation.
7. Data export: Connect to the computer through the USB interface and export the stored 80,000 sets of data for analysis.
8. Charging: Charge the built-in 18650 rechargeable battery with a USB DC 5V power supply.
Notice
* Do not operate the equipment in an environment beyond the operating temperature (0~ 50 ° C) and humidity (0~ 90% RH) range, so as not to affect the measurement accuracy or damage the instrument.
* Avoid exposing the Sensor to corrosive gases or high concentration dust environments that can cause damage.
* Periodically calibrate Sensors to ensure the accuracy of measurement data. Please refer to the relevant specifications or usage for the specific calibrating period.
When setting the alarm value, please set it reasonably according to the safety standards of the actual application scenario.
* When not in use for a long time, it is recommended to turn off the device and charge the battery regularly to maintain battery performance.
When exporting or connecting data, make sure to use a compatible and stable USB cable and power supply.
Do not disassemble or modify the equipment yourself. If there is any malfunction, please contact a professional for repair.
