BH-90A-NH3 is a cost-effective Portable single Gas detector of BOSEAN brand, dedicated to detecting ammonia (NH3). The product adopts mainstream 8-bit micro-control technology, with the characteristics of fast Response speed, high Measurement accuracy, Stability and Repeatability. The fuselage is compact, easy to operate, and has a high-strength ABS material shell and IP65 protection level. It has good waterproof performance and can adapt to harsh working environments. The instrument is equipped with sound, light and vibration three-level alarm, which is safe and reliable, and the high and low alarm value is adjustable. Built-in 3.7V rechargeable lithium battery, long battery life.
1. Adopt Industrial Sensor to Ensure Reliability. 2. The mainstream 8-bit micro-control technology is applied, and the performance is stable. 3. The fuselage is compact, and the operation is simple and convenient. 4. With IP65 protection level, waterproof and dustproof. 5. Fast Response and High Sensitivity. 6. The battery has a long standby time and can operate continuously for more than 10 hours. 7. Support three-level alarm of sound, light and vibration, which is not easy to ignore. 8. High and low alarm values can be set as required. 9. Supports more than 30 types of Sensors, and can be flexibly configured according to customer needs.
The detector uses a diffusion-type Sampling method. The target gas in the environment (such as ammonia) diffuses into the interior through the ventilation hole of the instrument shell. The industrial-grade Electrochemical sensor (for NH3) at the core of the instrument reacts with the gas to generate an electrical signal proportional to the gas concentration. The signal is processed by the built-in 8-bit microcontroller, and finally the gas concentration value is displayed in real time on the 1.77-inch high definition screen. When the concentration exceeds the preset high or low alarm value, the instrument will trigger an acoustic, optical and vibration alarm.

1. Press the power button for a long time to turn it on, and the instrument will self-test. 2. After the self-test is completed, the instrument enters the normal working state, and the screen displays the real-time gas concentration. 3. Through the menu button, you can enter the setting interface to view or modify parameters such as high and low alarm values. 4. Place the instrument in the environment to be tested to ensure that the Sensor part is not blocked. 5. Observe the screen reading, if the concentration exceeds the standard, the instrument will automatically trigger the alarm. 6. After use, press the power button for a long time to shut down. 7. When the power is insufficient, use the matching charger to charge the instrument.
• Do not use outside the -20~ 50 ℃ Temperature range or 0~ 95% RH (non-condensation) Humidity range. • Avoid instrument from being strongly impacted or immersed in water for a long time. • Do not disassemble or replace the Sensor by yourself. The Sensor life is about 2 years and needs to be calibrated regularly. • Please use the original charger when charging, and the Charging time should be less than 5 hours. When the instrument alarms, please take immediate safety measures and evacuate to a safe area. • The instrument is explosion-proof (Exib IIB T3 Gb), but still needs to be used under safety regulations. The instrument can record 1000 sets of alarm data, please check and manage it regularly.
