Beebird™ NH3 Analyzer Module

    HealthyPhoton introduced BeebirdTM -- the next-generation QCL based, cost-effective OEM solutions for ultra-sensitive NH3 online monitoring . This lightweight and compact measurement unit includes a variety of communication interfaces. Before deployment, users can test, calibrate and read data through the PC interface. The unique mid-infrared spectral analysis determines the performance of the product far exceeds the current generation products. The characteristics of the semiconductor production process determine the volume price will be very competitive.
