2. Safety Information
Please read this manual thoroughly before operating the device to ensure safe and effective use. Improper use may lead to inaccurate readings or damage to the device. Always operate the detector within specified environmental conditions.
Ammonia Hazard Index
Understanding ammonia concentration levels is crucial for safety. Refer to the following guidelines:
Image: A chart detailing the hazard index of ammonia gas to the human body, ranging from sensory odor threshold (5 ppm) to severe cough and potential death (2500 ppm). The detector is shown mounted on a tripod, demonstrating hands-free operation.
- 5 ppm: Sensory odor threshold; some people may detect an odor.
- 20 ppm: Most people experience obvious irritation; considered harmless.
- 20-30 ppm: Time-weighted safety threshold.
- 100 ppm: Most people feel uncomfortable; generally harmless.
- 250 ppm: Stimulates the nose, throat, eyes, and other senses.
- 400 ppm: Eye pain, tears for 30 minutes.
- 700 ppm: The limit that the human body can endure; not advisable to stay.
- 2500 ppm: Severe cough, irritation of the nose, throat, etc.; 15 minutes may cause death.

4. Setup
4.1 Unboxing
Carefully open the packaging and remove the GR-5800G detector and its accessories. Ensure all components listed in the package content are present.
Image: The package contents include the GR-5800G detector, a USB charging cable, a user manual, a packaging box, and a protective carrying bag.
4.2 Charging the Device
Before first use, fully charge the device. Connect the provided USB cable to the charging port (DC 5V) on the side of the detector and plug the other end into a suitable USB power source. The charging indicator light will provide feedback on the charging status. A full charge provides up to 30 hours of continuous use.

4.3 Sensor Preparation
Remove the protective cap from the sensor at the top of the device before operation to allow for proper air circulation and accurate readings.
Video: This video demonstrates the unboxing of the Ammonia Gas Detector, showing how to remove the sensor cap, power on the device, switch between Celsius and Fahrenheit, and set the alarm thresholds. It provides a visual guide for initial setup and basic operation.
5. Operation
5.1 Power On/Off
Press and hold the central power button to turn the device on or off. The LCD display will illuminate upon activation, showing current readings.
5.2 Temperature Unit Conversion
Press the '°C/°F' button to toggle the temperature display between Celsius and Fahrenheit.
5.3 Setting Alarm Thresholds
The device features two alarm thresholds (AL1 and AL2) for ammonia concentration. When the detected ammonia level exceeds these thresholds, the device will alert you with light and sound.
- Press the 'ALARM' button to enter the alarm setting state. The display will show "AL1".
- Use the increment (up arrow) and decrement (down arrow) buttons to adjust the value for AL1. A short press adjusts by 0.1 ppm, a long press adjusts by 1 ppm.
- Press the 'ALARM' button again to switch to "AL2" setting mode.
- Adjust the value for AL2 using the increment and decrement buttons.
- Press the 'ALARM' button a third time to save the settings and exit.

5.4 Auto Power Off (APO) Function
The device includes an auto power off function to conserve battery life.
- Press the 'MODE' button to cycle through settings. The display will show "APO ON" or "APO OFF".
- Use the increment/decrement buttons to enable ("APO ON") or disable ("APO OFF") the auto power off function.
- Press the 'MODE' button again to save the setting and exit.
5.5 Taking Measurements
Once powered on, the device will automatically begin detecting ammonia, temperature, and humidity. Ensure the sensor is exposed to the air in the area you wish to monitor. For stable, continuous monitoring, utilize the tripod screw hole on the back of the device to mount it on a tripod.

6. Maintenance
6.1 Cleaning
To maintain optimal performance, regularly clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or internal components. Keep the sensor area free from dust and debris.
6.2 Sensor Care
The electrochemical sensor has an extended lifespan of over two years under normal operating conditions. Avoid exposing the sensor to extreme temperatures, high humidity, or corrosive gases for prolonged periods, as this can reduce its accuracy and lifespan. Do not attempt to clean the sensor directly with liquids or sharp objects.
