Digital pH Sensor

Product Name: Digital pH Sensor

Product model: FLD1701CD

Product brand:FLUIDINGS

Power supply voltage: 9-36VDC

Purpose: To measure and control pH value of water samples for industrial and production water treatment, easy to connect to PLC, DCS, industrial control computers, general purpose controllers, paperless recording instruments or touch screens and other third party devices.


DESCRIPTION



lThe long-distance reference diffusion path greatly prolongs the service life of the electrode in harsh environments. With built-in temperature sensor (NTC10K, Pt100, Pt1000, etc. can be selected according to user requirements) and wide temperature range, it can be used in explosion-proof areas. 

 

lThe newly designed glass bulb increases the bulb area, prevents the generation of interfering bubbles in the internal buffer, and makes the measurement more reliable. Adopt PPS/PP shell, upper and lower 3/4NPT pipe thread, easy to install, no need for sheath, and  low installation cost. The electrode is integrated with pH, reference, solution grounding, and temperature compensation. 

 

lThe electrode adopts high-quality low-noise cable, which can make the signal output longer than 20 meters without interference. 

 

lThe electrode is made of ultra-bottom impedance-sensitive glass film, and it also has the characteristics of fast response, accurate measurement, good stability, and not easy to hydrolyze in the case of low conductivity and high purity water.
