英國MUNRO水質(zhì)探頭/150/ WQ10水質(zhì)探頭

這個(gè)多功能探頭有利于大范圍水質(zhì)參數(shù)的測量。

光學(xué)溶解氧（DO）：水質(zhì)的主要指標(biāo)之一，是測量在水中溶解氧的濃度。

相對電導(dǎo)率(EC)

Absolute Electrical Conductivity (EC): Provides an indication of the presence of inorganic dissolved solids and therefore the purity of water. Pure water is an extremely poor conductor of electrical currents and therefore a change in EC can suggest degradation of water quality.

Specific Electrical Conductivity (EC): The EC adjusted to reflect the temperature of the water being tested.

水酸度（PH）：

Water Acidity (pH): Aquatic organisms are often sensitive to the acidity of water. Therefore, monitoring and maintaining the pH balance is important in many situations.

氧化還原電勢（ORP）：

Oxidation Reduction Potential (ORP): Oxidation is the loss of electrons by a chemical species following the introduction of a new species. The corresponding reaction is the reduction process in which chemical species gain electrons. ORP is therefore an indication of the potential for oxidation or reduction reactions to take place.

溶解性總固體（TDS）

Total Dissolved Solids (TDS): Indicates the concentration of minerals, salts, metals and ions

dissolved in water.

Resistivity: The ability of water to resist an electrical current. This is the opposite of EC. Therefore, a body of water with a high EC will have a correspondingly low resistivity.

Salinity: Provides a value for the concentration of dissolved salts in the water.

海水比重

Seawater Specific Gravity (SSG): A measure of the density of water. Saltwater is more dense than pure or freshwater.

溫度

Temperature: Affects a number of chemical processes that take place in water.

Depth: Indicates the depth using EC.
