Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
Fluorescent optical sensor has the following salient features:
● The measurement does not consume oxygen, regardless of the sample flow rate, the measurement is stable.
● No electrolyte and electrode film, without preheating and regular calibration, easy to use.
● Fluorescent cap coated with light-shielding layer, not affected by external light source; Non-chemical sensors, measuring water from the various heavy metal ions, H2S and NH4 and other chemical interference.
● In addition to mechanical damage (such as scratch the light barrier), fluorescent cap up to 8000 hours of life. Supporting electrode calibration kits, calibration and maintenance more convenient and reliable.
Intelligent meters have the following salient features:
● Automatic temperature compensation, automatic pressure compensation, manual salinity compensation.
● Large white LCD backlight, clear display.
● Stable reading mode and automatic lock display mode.
● IP57 waterproof grade, standard equipment suitcase.
