The measurement of sea water pH. Marine Chemistry 44, 131-142.Dickson, A. G.: The measurement of sea water pH, Mar. Chem., 4, 131-142, 1993.Dickson,A.G. The measurement of sea water pH[J].Marine Chemistry,1993,(2-4):131-142....
pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
Utilising the measurement chamber for calibration in this way reduces the volume of calibration solution required, which in turn reduces maintenance costs.Smart Sensors Water testing probes in the PRO range come complete with all of the key water quality smart sensors as standard and are equipped wi...
Although ESP is a criterion for classifying sodic soils (Table 10), the accuracy of its values is questionable due to errors that may occur in the measurement of C.E.C and exchangeable Na. Therefore, to detect the risk of soil sodicity, the SAR of the saturated extract, which is more ...
Using the AP-2000-D as a water level logger The AP-2000-D features a Depth Sensor. This sensor is capable of measurement accuracy of 0.5%FS. This is very comparable to a dedicated water level logger such as the LeveLine-ECO: 0.2%FS, and the LeveLine (titanium): 0.1%FS. The depth ...

Temperature measurements were taken as soon the water was sampled to investigate if there was any thermal input in the well water. The electrical conductivity of the water samples was measured using a conductivity meter under standard conditions of temperature and pressure. Measurement of conductivity ...
Measurement of the kinetics of natural assemblies of marine \({{\rm{N}}{\rm{H}}}_4^ +\) oxidizers29 show a lower half-saturation constant than Nitrosopumilis (27.2 ± 4.4 vs. 133 ± 38 nM \({{\rm{N}}{\rm{H}}}_4^ +\)) with respect to a bulk \({{\rm{N...
It may be mentioned that the water parameters viz. Salinity, DO, TSS and pH were analyzed within 4–8 hours of collection using standard methods. In situ measurement of salinity in ppt and DO in mg/l were carried out using pre-calibrated YSI instrument (YSI model 85, accuracy with ±...
The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. Seawater is abundant but must be desalinated before use in typical proton exchange membrane (PEM) electrolysers. Here we report direct electrolysis of real seawater that has ...
