Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
Fluorescent optical sensor, has the following salient features:
● Measurement does not consume oxygen, not affected by the sample flow rate, measurement stability.
● No electrolyte and electrode film, without preheating and regular calibration, easy to use.
● The fluorescent cap is coated with a light-shielding layer that is not affected by external light sources. Non-chemical sensors are not affected by chemicals such as heavy metal ions, H2S and NH4 in water.
● In addition to mechanical damage (such as scratch the light barrier), the fluorescent cap has a service life of up to 8000 hours. Supporting electrode calibration kits, calibration and maintenance more convenient and reliable.
Smart meters, with 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.
