Smart Sensor ST8900 Multi Gas Monitor 4 in 1 Detector

Product Description

Mendeteksi 4 jenis gas: karbon monoksida (CO), hidrogen sulfida (H₂S), oksigen (O₂) dan gas mudah terbakar (LEL).
Pantau terus konsentrasi gas CO, H₂S, O₂, dan LEL di lingkungan sekitar dengan pengukuran yang profesional dan akurat.
Alarm getaran suara & cahaya bekerja ketika salah satu konsentrasi gas CO, H₂S, O₂ & LEL mencapai tingkat alarm.
Dapat mengatur waktu shutdown otomatis dan konsentrasi nilai alarm.
Layar LCD besar dengan lampu latar.
Dapat terhubung ke pompa pengambilan sampel untuk beroperasi di tempat tertutup.
Banyak digunakan dalam pengiriman, pertambangan, eksploitasi minyak, kimia, pipa gas, konstruksi terowongan, batu bara, metalurgi, kertas, api, kota, tekstil dan industri lainnya.
