Analisis konsentrasi garam alkali asam cerdas NMD-99 adalah instrumen pemantauan online kontinu baru yang dirancang berdasarkan prinsip metode induksi elektromagnetik.
Sensor tidak bersentuhan dengan medium, sehingga tidak ada efek polarisasi.
Alat ini memiliki keunggulan yang tak tertandingi dibandingkan dengan sensor umum dalam pengukuran konsentrasi dan konduktivitas online kontinu asam, alkali, garam, medium korosif, dll.
Key Features
Measuring range: Conductivity: 0~1999mS/cm
Temperature: -20~60 DegC (PT1000)
Measuring Medium: Hcl, H2SO4, HNO3, NaOH, Nacl, H3PO4
Electromagnetic detecting element doesn’t contact with the measured medium directly. There is no electrode polarization effect, nearly no need maintenance.
MODBUS RS485 digital output, 4~20mA analog output.
Power supply: AC85-265V, 50/60Hz, 10W.
