High Accuracy Water Quality Tester. This Total Dissolved Solids (TDS) meter measures the quantity of any salt, metal or mineral or other contaminants that may be present in your water source. With the push of a button, the TDS meter will indicate your overall water purity level which is measured in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS meter is great for checking your tap water, aquarium, or any other source. It can be used to determine if your filters need to be replaced. Usage: The Starden TDS meter is very simple to use. Just follow these simple steps: ①Remove protective cap. ② Press the "on" button and place the unit into about an inch of water. ③ Wait for the reading to stabilize to see your final reading. Compare your readings against the to following to determine the quality of your water: ✓ Ideal PPM Range for drinking water from reverse osmosis, distillation, deionization, microfiltration, filters 0 - 50 PPM ✓ Ideal Range for carbon based filters, mountain springs or aquifers. 50 - 150 PPM ✓ Ideal range for average tap water: 150 - 400 PPM ✓ Generally any value over 500 is considered unsuitable for human consumption The water we drink is this planets most precious resource, each year more and more of our water supply is being contaminated making it unsuitable for human consumption. Don't assume that the water you're drinking is safe to drink. Know for sure by periodically testing it with this meter.

The Thomas 4365 Traceable Conductivity meter is a waterproof, pen-style instrument designed for easy routing analysis and quality control, with automatic or manual range selection. The LCD screen displays readings in digits that are 0.5†in height, and the meter housing is ABS plastic for durability in harsh laboratory or plant environments. Automatic shutoff after 20 minutes of non-use helps preserve battery life. Conductivity meters are commonly used in the water-quality testing, waste-water treatment, hydroponics, agriculture, and aquaculture industries, in cosmetics manufacturing, and in laboratory research. To ensure accuracy, the meter includes an individually serial-numbered Traceable certificate from an ISO 17025 calibration laboratory accredited by the American Association for Laboratory Accreditation (A2LA). The certificate indicates traceability to standards provided by National Institute of Standards and Technology (NIST). The meter also fulfills requirements for CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, ISO, and federal and state regulations. Specifications Conductivity range 0 to 1999μS, 0.00 to 19.99mS Conductivity resolution 1, 0.01 Temperature compensation Automatic from 0.0 to 50.0 degrees C, with temperature coefficient equal to 0.0 to 4.0% per degree C, 0.1 increments Power source Four 357/LR44 silver oxide batteries Dimensions 6.5 x 1.25 x 1.25†(H x W x D)Weight2.25oz Conductivity meters, also known as electrical conductivity (EC) meters, measure the ability of a solution or material to conduct an electrical current. This measurement helps determine if the solution is, for example, contaminated or contains too much saline. In general, pure solutions, such as distilled water, have low conductivity. More saline- or nutrient-rich solutions, such as seawater or fertilizers, have high conductivity. Conductivity measurements are often used with total dissolved solids (TDS) measurements, which are typically expressed in ppm (parts per mill...

The Oakton 35661-08 replacement conductivity/TDS electrode is made with 316 stainless steel for strength and chemical resistance, and works with the Oakton TDSTestr 11+, ECTestr 11+, and SaltTestr portable meters. A replacement electrode, also called a sensor or probe, is used with a meter to measure the total dissolved solids (TDS) and electrical conductivity (EC) of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This electrode has a cup-style to grab or draw samples, and has an easily gripped ribbed collar attachment system for ease of electrode replacement. It has a replaceable sensor to extend tester life. Its waterproof and dustproof housing is Valox resin, and the meter has Ingress Protection (IP) 67-rating for protection against solid objects or liquids. The 35661-08 electrode has an integral stainless steel sensor, and works with the Oakton TDSTestr 11+, ECTestr 11+, and SaltTestr portable pocket meters. TDS, such as salts and minerals, contribute to the conductivity of a solution. A TDS meter measures substance conductivity and converts it to a TDS reading. TDS readings are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing, and for scientific applications. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

What is TDS? Total Dissolved Solids(TDS) are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water,expressed in milligrams per liter (mg/L) or in parts per million (PPM). About TDSThe lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water you drink; The higher the TDS level in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. The EPA's maximum contaminants levels of TDS in secondary drinking water is 500mg/L( (500PPM) Why buy Poit TDS Meter?The Poit TDS Meter with advanced CPU that automatically calibrated per temperature.
