Product: AQL TDS Meter
TDS Meter is a conductivity pen ATC for the measurement of TDS (total dissolved solids). And 'one of the smallest and lightest TDS meter on the market. And 'ideal for measurements in the treatment and purification of water, aquaculture, hydroponics, reverse osmosis systems and all applications which need to know the value of purity of the water used or to be treated.
The TDS or total dissolved solids is the amount of minerals, salts, metals, anions and cations present in a given volume of water and is expressed in ppm (parts per million). Its value is directly related to water quality. The higher the measured data and the lower the purity of the water. The EPA (U.S. Environmental Protection Agency) recommends a maximum of 500 ppm / l and 1000 ppm / l for human consumption.
Highly efficient and accurate due to advanced microprocessor technology
Auto power off. The unit turns off after 10 minutes of non-use for a longer battery life.
Double automatic reading. From 0-999 ppm with a resolution of 1 ppm and from 1000 to 9990 with a resolution of 10 ppm with an indication on the display of the "X10" flashing.
The instrument comes supplied calibrated. Can be calibrated with a mini screwdriver and the solution 342 ppm NaCl.
Automatic temperature compensation
Measuring range: 0 to 9990 ppm
Accuracy: + / - 2%
ATC electrode for automatic temperature compensation
Battery power supply included in the package (2 x 1.5V)
