Comprehensive guide for your INKBIRDPLUS Air Quality Monitor

1. Introduction

The INKBIRDPLUS Indoor CO2 Detector (Model PTH-9C) is a multifunctional air quality monitor designed to accurately detect and display the current CO2 concentration, temperature, and relative humidity in the air. This device provides essential information to help you maintain optimal indoor air quality in various environments such as grow tents, wine cellars, homes, offices, and cars.

Understanding your indoor air quality is crucial for health and comfort. The PTH-9C offers a clear, distinct LED screen for easy data viewing and features an alarm system to alert you when CO2 levels exceed customized safe values.

2. Product Features

  • Premium Detector: Accurately detects CO2 concentration, temperature, and humidity.
  • CO2 Concentration Stage & Sound Alarm: Features 3 stages (Normal: 400-700 ppm, Warning: 700-1500 ppm, Dangerous: 1500-5000 ppm) with a customizable sound alarm for unsafe CO2 levels.
  • Convenient Calibration: Supports calibration for accurate measurements using a simple three-button press in an open environment. Utilizes an NDIR CO2 sensor.
  • Long Battery Standby: Equipped with a 2400 mAh lithium battery for extended continuous use. Features a large, distinct LED screen for easy viewing.
  • Wide Application: Portable design with a hanging hole, suitable for grow rooms, offices, kitchens, schools, cellars, and cars.

4.2 CO2 Concentration Stages and Alarm

The device categorizes CO2 levels into three stages, indicated by color changes on the display and an optional audible alarm:

  • Normal Stage: 400-700 ppm (Green indication)
  • Warning Stage: 700-1500 ppm (Yellow indication)
  • Dangerous Stage: 1500-5000 ppm (Red indication)

The device will emit an audible alarm when the detected CO2 concentration exceeds the safe value you have customized. To set or adjust the alarming value, double-press the appropriate button (refer to the device's physical buttons for exact labeling, typically the 'UP' button).

CO2 Warning Alarm feature
The detector will alarm when CO2 concentration reaches a preset value. Double-press to enter alarming value settings.

4.3 Temperature Unit Selection

To switch between Celsius (°C) and Fahrenheit (°F), press the 'UP' button (often labeled with a '+' symbol) on the top of the device.

4.4 Charging the Device

The device is powered by a built-in 2400 mAh lithium battery. When the battery indicator shows low power, connect the device to a 5V-1A power source using the USB-C cable. Due to the presence of three sensors, continuous operation is best achieved by keeping the device plugged in.

Convenient USB Charging
The INKBIRDPLUS CO2 Detector features convenient USB charging with its 2400 mAh large-capacity battery.

5. Maintenance

To ensure the longevity and accuracy of your INKBIRDPLUS CO2 Detector, follow these maintenance guidelines:

  • Cleaning: Gently wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the screen or casing.
  • Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
  • Regular Calibration: While the device uses an NDIR sensor for high accuracy, periodic calibration in a fresh air environment (as described in the Setup Guide) is recommended to maintain optimal performance over time.
  • Avoid Obstructions: Ensure the sensor vents on the device are not blocked by dust, debris, or other objects, as this can affect reading accuracy.

6. Troubleshooting

If you encounter issues with your INKBIRDPLUS CO2 Detector, refer to the following common problems and solutions:

ProblemPossible CauseSolution
