Vendeur: top-messtechnik (61.702) 99%, Lieu où se trouve: Erding, Lieu de livraison: Worldwide, Numéro de l'objet: 351907652874 Description: Drinking water OK? Water change necessary? Osmose water OK? Resins of demineralizer OK? This EC measuring instrument EC-1382 is small, handy and ultraportabel. Ideal employment in aquaristic, drinking water production, cleanliness of swimming pool and pool, landed on water, storage water heater water, household, office, aquarium, teaching material for physics and chemistry lessons, galvanic shop, ionized water and laboratory. The values are well readable with the large clear display. The EC meter will come with a storage box. EC/ TDS/ Conductance/ Conductivity in practice use: In the aquaristic is the conductance (conductivity) apart from the pH value an important character-istic for the water quality. With this EC meter you can examine the quality of the pure water from your osmose device or full demineralizer or the quality of your aquarium water/ blend water with the water change. Example 1: The measurement in the fresh water aquarium results in 600 µS/cm, in the tap water however 300 µS/cm. Thus a partial water change is to be done. Example 2: Examine the quality of your water. As appoximate values to water is considered generally: Water to 120 µS as very good deslagging and is favorable to health. Of 300 - 600µS is the water rather loading and starting from 600 µS it is to be designated as bad . Example 3: In the case of control in the sea water basin 53000 results µS/cm. From the usual conductivity tables of sea water (with 25°C) you read a content of salt of 35 parts per thousand with 53,8 (mscm) off. Sea water is correct. Example 4: With control of your permeat of a reverse osmosis device you obtain a measured value from 20 µS/cm. The permeat is thus correct. Click here for further calibration and maintanance liquids What is the electrical conductivity actually? With demineralized water, no solved CO2 contained you measures the conductivity zero (actually it would be 0.055 µS/cm). That corresponds to the intrinsic conductivity of the water (h-ions and OH ions dissociate). In the qquaristic applies: Demineralized water has practically no conductivity. The addition spoon common salt (10g) into a litre demineralized water causes a value of 15000 µS/cm. The common salt (NaCl) dissolves completely in sodium ions (Na+) and chloride ions (Cl -) and so an ionic conduction is produced. - More EC-Meters and other measuring devices to special prices in our shop - Technical details: Measuring range: 0 bis 1999µS/cm Resolution: 1µS/cm Measuring accuracy: ± 2% Operation temperature: 0 °C - 50 °C Power supply: 4x 1,5V (AG13) Weight: 60 g Dimension: 60mm x 55mm x 23mm Conformity: CE-konform EN 50081-1 and EN 50082-1 Marque: OCS.tec
