Vendeur: top-messtechnik (61.133) 99.2%, Lieu où se trouve: Erding, Lieu de livraison: Worldwide, Numéro de l'objet: 361842371928 Description: Drinking water OK? Water change necessary? Osmose water OK? Resins of demineralizer OK? Our professional conductivity measuring instrument YK-2005CD is one of the most exact and most progressive devices presently available. By the enormous measuring range of 0µS - 200mS and 0 - 132,000 PPM a universal use is possible. A for this equipment specially designed LSI circuit provides a high measuring accuracy and quick gate times. With the external probe (carbon rod electrode) you can reach every measuring point. More quality characteristics: - data-hold function - auto shut-off - RS-232 interface - automatic storage of measuring values (up to 16.000 data) Ideal for use in food processing, cleanliness of swimming pools, water test, paper and beverage industry, laboratory, school and college for the physics and chemistry lessons, aquarium, office, fish farming, household and boiler water. 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. - Many further measuring instruments to special prices in our shop - Technical details: Display: large LCD-Display (58mm x 34mm) Measuring range: 0 µS/cm bis 200 mS/cm 0 - 132.000 PPM Resolution: 1µS/cm - 0.1ms/cm 0.1 PPM - 100 PPM Measuring accuracy: ± 2% Automatic temperature compensation: 0°C - 60 °C variable: 0 - 5 % Operating environment: Device: 0 °C - 50 °C Probe: 0 - 60 °C Humidity : 80% Power supply: Battery: 4x 1.5 V Weight: 425 g Dimension: 203 mm x 76 mm x 38 mm Conformity: CE-konform EN 50081-1, EN 50082-1, ISO 9001 Marque: OCS.tec
