Laser Gas Analyzer menggunakan Tunable Diode Laser Absorption Spectroscopy (TDLAS), realisasi pengukuran non kontak dalam suhu tinggi, tekanan tinggi, debu tinggi, dan kondisi uji keras lainnya. Laser selektif tinggi berdasarkan frekuensi, alat analisa memiliki kinerja anti interferensi yang baik. Dibandingkan dengan metode analisis tradisional, mengurangi sistem sampling yang kompleks, instalasi yang fleksibel dan mudah digunakan, sangat mengurangi instalasi manual dan beban kerja pemeliharaan.
- Selektivitas yang sangat tinggi terhadap gas sasaran
- Keamanan fungsional, pelaporan status berkelanjutan
- Umur panjang (10+ tahun)
- Waktu respons yang cepat
- Konsumsi daya rendah
- Biaya kepemilikan yang sangat rendah (tidak ada penggantian dan / atau kalibrasi reguler)
- Biaya rendah sensor gas melalui biaya penskalaan komponen yang sangat baik
