There are many ways to measure EC, but most common way of measuring EC that I found on the Internet can be traced back to a design described in September 1977 issue ofElectronicsmagazine on an article"One-chip conductivity meter monitors salt concentration"by Michael Ahmon. Ahmon's design c...
Here comes an analog pH meter, specially designed forArduino controllersand has built-in simple, convenient and practical connection and features. It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. To use it, just connect the pH sensor with BNC conn...

Abundances of hundreds per square meter have been reported. The multinucleate protoplasm is enclosed within a labyrinthine organic tube encrusted with foreign particles. The organism also contains numerous crystals of barium sulfate, which have no obvious function. Growth is episodic, with intervening ...

But, when ultraviolet radiation is 56 made to fall on A, there is no deflection in the galvanometer. These observations reveal that the particles emitted by the plate C due to the photoelectric effect are negatively charged. These particles were found to be electrons. The observed current ...
The pH of the medium was measured with a pH meter (Sension + pH3, HACH, USA). Salinity was measured with a salinity refractometer (Diesella, UK). Nitrates were measured following the APHA Method 4500-NO3 (Baird et al. 1992)., Briefly, this measurement method is based on the ...

The UV-Vis analyses of the aqueous aluminium solutions were performed on a Spec- trometer CamSpec M550 (Spectronic CamSpec Ltd., Leeds, UK). The electrochemical processes were followed up with a PARSTAT 2273 Potentiostat (Princeton Applied Research, AMETEK Inc., Oak Ridge, TN, USA). It has...
