2. Key Features
- High Range Ammonia Gas Detection: Measures ammonia gas from 0 to 100 PPM, ammonia gas resolution 0.1 PPM, accuracy +/- 2%. Measures ambient temperature from -10 ~ 50 ℃, ℃/℉ switchable.
- Ammonia & Temp & Humidity Meter: In a humid, warm environment, ammonia gas is produced faster. Therefore, while detecting ammonia gas, you should also keeping track of the temperature (℃/℉) and humidity.
- Tripod Hole for Mounting: Assembled with electrochemical cell sensor for sensitive measurement. With a tripod mount port so you can mount the meter and have it measure ammonia (NH3) Gas Density continuously, keep track of the gas changing in the same spot. Perfect ammonia air detector for poultry farms, horse stables, livestock.
- Rechargeable Ammonia Air Gauge: The included USB cable can be connected to the plug for charging. Built with green / red charging indicator light. Remaining power indicator, Auto / Manual power off optional to save your battery.
- Alarm Indicator Light: AL1 and AL2 alarm limit values are adjustable. Slow light flash and buzzer indicates alarm level “AL1” reached, Rapid light flash and buzzer indicates alarm level “AL2” reached. This handheld Ammonia detector portable and comes with storage case for testing around.

4. Setup
- Unboxing: Carefully remove the BT-5800G detector and all accessories from the packaging. Verify that all components listed in Section 3 are present.
- Initial Charge: Before first use, fully charge the device using the provided USB cable. Connect the cable to the DC 5V charging interface on the device and a suitable USB power source (e.g., computer USB port, wall adapter). The charging indicator light will show red during charging and turn green when fully charged.
- Power On: Press and hold the power button (center button with power symbol) to turn on the device. The display will illuminate and show current readings.
- Placement: For continuous monitoring, utilize the tripod mount port located at the bottom of the device to secure it in the desired measurement area. This ensures consistent data collection from a specific point.

5. Operating Instructions
- Power On/Off: Press and hold the power button to turn the device ON or OFF.
- Temperature Unit Selection: Press the "°C/°F" button to switch between Celsius and Fahrenheit temperature units on the display.
- Setting Alarm Limits (AL1/AL2):
- Press the "ALARM" button to enter alarm setting mode.
- Use the Up (▲) and Down (▼) arrow buttons to adjust the AL1 and AL2 alarm thresholds.
- Press "ALARM" again to confirm and cycle through settings.
- Auto/Manual Power Off: Press the "MODE" button to toggle between Auto Power Off (APO) and Manual Power Off modes. In APO mode, the device will automatically shut down after a period of inactivity to save battery.
- Reading Measurements: The large digital display shows real-time ammonia concentration in PPM, relative humidity (%RH), and temperature (°C/°F).
- Interpreting Alarms:
- A slow light flash and buzzer indicate that the "AL1" alarm level has been reached.
- A rapid light flash and buzzer indicate that the "AL2" alarm level has been reached.

6. Maintenance
- Cleaning: Wipe the device exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor area is kept clean and free from dust or debris.
- Storage: When not in use, store the BT-5800G in its provided carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: Recharge the battery regularly, even if the device is not frequently used, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Sensor Lifespan: The electrochemical cell sensor has an estimated lifespan of two years. Regular calibration and replacement may be necessary to maintain accuracy over time.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the device using the provided USB cable. Ensure the charging indicator light is red. |
| Inaccurate ammonia readings (e.g., 0.0 PPM near source). | Sensor obstruction or malfunction; device not calibrated. | Ensure the sensor is clear of obstructions. If issues persist, contact customer support for potential calibration or service. |
| Temperature/Humidity readings seem incorrect. | Environmental factors; sensor issue. | Allow the device to acclimate to the environment. If discrepancies continue, refer to specifications for operating conditions. |
| Alarm not sounding or flashing. | Alarm limits set too high; device malfunction. | Verify alarm settings (AL1/AL2) are appropriate for the desired detection levels. |
