  • A Low-Cost Electrolytic Tiltmeter for Measuring Slope Deformation

    The tiltmeter described consists of an electrolytic sensor (a glass jar containing an electrolyte and six electrodes) and a portable AC digital conductivity meter, which reads conductivity changes resulting from tilting deflections. The tiltmeter has a sensitivity of 2 to 8 min of arc/cmu (conductivity meter unit), with a measurement range of more than 45°. This tiltmeter measured earth flow ...

  • Electrochemical synthesis of polypyrrole for biosensor application

    Polypyrrole nanowires were electrochemically synthesised on platinum electrode at ambient temperature. The potentiostatic potential was set at 0.75 V in the presence of gelatin as soft mould. The whole process only took few hundred seconds. The morphologies, chemical composition and conductivity of nanowires were evaluated by means of Scanning Electron Microscopy (SEM), Fourier Transform Infrared ...

  • Reliable pH measurement in Oily applications

    pH measurement in the petrochemical industry is frequently extremely difficult. Operating in high temperatures with highly reactive contaminants traditional pH reference electrodes can, in some applications, last only days. IC Controls 613 sensors reference is designed for difficult applications particularly where fouling or poisoning conditions exist. The reference uses a highly stable ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Get the scoop on the newest technology for the measurement of pH

    SENTRON had its 20th birthday in April 2005 and is world wide known as the manufacturer of glass free ISFET (Ion Sensitive Field Effect Transistor) pH systems. During the 20 years we developed and manufactured not only ISFET pH sensors but also pressure sensors in our own silicon chip production facility. This facility for development and manufacturing of solid-state sensors, enables us to ...

  • Detection of trace cobalt ions in in vivo plant cells using a voltammetric interlocking system

    This experiment was conducted to establish a system for detecting trace cobalt ions in water and plant tissues using a voltammetric in vivo sensor. Cyclic and stripping voltammetry was devised from hand-made, macro-type implantable three-electrode systems. The results reached micro and nano working ranges at 100 sec accumulation time. The statistical detection limit (S/N) was attained at 6.0 ...
