Setup
1. Initial Charging
Before first use, fully charge the device. Connect the provided USB charging cable to the DC 5V charging port on the device and plug the other end into a standard USB power adapter (not included) or a computer USB port. The charging indicator light will illuminate during charging and turn off or change color when fully charged. A full charge provides up to 30 hours of continuous operation.
2. Powering On/Off
To power on the device, press and hold the Power ON/OFF button until the LCD display illuminates. To power off, press and hold the same button until the display turns off.
Operating Instructions
1. Basic Measurement
Once powered on, the device will automatically begin measuring ammonia concentration (ppm), relative humidity (%RH), and temperature (°C/°F). These values are displayed simultaneously on the LCD screen.
2. Changing Temperature Units
Press the °C/°F Switching button to toggle the temperature display between Celsius (°C) and Fahrenheit (°F).
3. Setting Alarms
The device features two alarm thresholds (low and high). When the ammonia concentration exceeds these thresholds, the device will emit an audible beep and a visual light alarm.
- Press the Alarm Setting button to enter alarm setting mode.
- Use the Increment and Decrement buttons to adjust the low alarm threshold.
- Press the MODE key to switch to the high alarm threshold setting.
- Use the Increment and Decrement buttons to adjust the high alarm threshold.
- Press the Alarm Setting button again to save the settings and exit alarm mode.
Figure 4: Dual Alarm System. This image illustrates the device's alarm functionality, which includes both audible and visual alerts when ammonia levels exceed set thresholds.
4. Hands-Free Monitoring
The device includes a screw hole on its back for mounting onto a standard tripod (not included). This allows for stable, continuous, and hands-free monitoring in a fixed location.

Maintenance
- Cleaning: Wipe the device exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the sensor opening or charging port.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective carrying bag for storage and transport.
- Battery Care: Recharge the battery regularly, even if the device is not in frequent use, to maintain battery health. Avoid completely draining the battery for extended periods.
- Sensor Life: The electrochemical sensor has an estimated lifespan of over two years. Regular calibration is recommended for professional applications to ensure continued accuracy (calibration services not detailed in this manual).
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Connect the device to a USB charger and allow it to charge for at least 2 hours. |
| Inaccurate readings. | Sensor contamination or end of sensor life. | Ensure the sensor area is clean. If issues persist, the sensor may require professional calibration or replacement. |
| Alarm not sounding. | Alarm thresholds set too high or alarm function disabled. | Check and adjust alarm settings as described in the “Operating Instructions” section. Ensure the environment’s ammonia level is above the set threshold. |
| Display is dim or flickering. | Low battery. | Recharge the device immediately. |
