• Triple Alarm System: Audible, visual and vibration alarms provide multiple warning methods.
• Adjustable Alarm Levels: High and low alarm thresholds can be configured according to monitoring requirements.
• Natural Diffusion Sampling: Continuously detects ambient gas without requiring an external sampling pump.
• Digital LCD: Displays ammonia concentration and operating status for quick field inspection.
• High-Strength Housing: Compact construction is designed for portable industrial and agricultural use.
• Rechargeable Operation: Built-in rechargeable power supports mobile monitoring without continuous mains power.
• Flexible Sensor Platform: The BH-90A series can be configured for different gases according to application requirements.

• Pig house ammonia concentration monitoring
• Poultry house air-quality inspection
• Cattle and goat-farming-equipment/" target="_blank" class="keylink">sheep housing areas
• Manure pits and manure handling zones
• Livestock waste treatment facilities
• Composting and organic waste areas
• Ventilation system performance checks
• Farm environmental safety inspections
• Worker exposure monitoring in livestock facilities
• Environmental troubleshooting during high-ammonia conditions

• Fully charge the detector before routine field use.
• Perform the required start-up and self-check procedures before entering the monitoring area.
• Keep the sensor inlet unobstructed during measurement.
• Allow sufficient stabilization time when moving between environments with significantly different temperature or humidity.
• Set suitable low and high alarm thresholds according to the site's safety and environmental monitoring requirements.
• Perform periodic calibration using suitable reference gas according to the manufacturer's instructions.
• Check alarm, battery and sensor status regularly.
• Clean the housing with a soft cloth and keep dust away from the sensor opening.
• Do not immerse the detector in water or clean it with corrosive solvents.
• Replace the gas sensor when its service life has expired or when calibration performance is no longer acceptable.

Q: What gas does this detector measure?
A: This configuration is designed specifically to detect ammonia gas, identified chemically as NH3.

Q: What is the ammonia measurement range?
A: The listed measuring range is 0–100 ppm.

Q: What is the minimum displayed reading?
A: The listed resolution is 1 ppm.

Q: How does the detector warn the operator?
A: It provides audible, visual and vibration alarms when the programmed alarm threshold is reached.

Q: Is it suitable for pig and poultry houses?
A: Yes. Portable NH3 monitoring is useful for identifying elevated ammonia levels in pig houses, poultry houses and other enclosed livestock facilities.

Q: Does the detector require a sampling pump?
A: No. The BH-90A uses natural diffusion sampling for ambient gas detection.

Q: How often should the detector be calibrated?
A: Calibration should follow the manufacturer's maintenance schedule and the requirements of the user's safety program. More frequent checks may be required in demanding operating environments.

Q: Can this detector control ventilation equipment automatically?
A: This handheld model is primarily intended for portable detection and alarm. Fixed ammonia sensors integrated with a farm environmental controller are more suitable when automatic ventilation control is required.
