Microprocessor EC-TDS-Sal Meter Manufacturer,Supplier and Exporter in India

Product Code : EL-CM-2189
Jlab Export is a leading Microprocessor EC-TDS-Sal Meter Manufacturer,and suppliers in India

Seawater, brackish groundwater and saline soils call for a salinity reading, and this microprocessor bench meter gives one next to conductivity, TDS and temperature. TDS and salinity are both calculated from the conductivity reading. The meter selects its range automatically, takes a programmable reference temperature and coefficient, and keeps up to 90 results for printing.

Water and Soil Salinity Practicals

A calibration-curve exercise starts with Sodium Chloride dissolved in Distilled Water and made up to the mark in Volumetric Flasks, Class A Borosilicate Glass Plastic Stopper JLab. Students read conductivity, TDS and salinity for each solution and plot them against the known salt content. The straight-line graph shows why conductivity can stand in for dissolved salt.

For an environmental survey, groups collect tap water, well or canal water and a saline soil extract, then compare the salinity readings in ppm and ppt. The Backpack Water Quality kit adds field tests on the same samples. The memory holds up to 90 readings until the class prints them.

Frequently Asked Questions

How is salinity different from TDS on this meter?
Both are worked out from conductivity. TDS estimates all the dissolved solids, while salinity expresses the result as dissolved salt. Here the TDS scale runs to 200 ppt and the salinity scale to 50 ppt, each over five ranges.

What does the adjustable cell constant setting do?
The cell constant links the conductance the meter measures to conductivity. Set it to the constant of the cell in use, anywhere from 0.05 to 10.5. To check it, read a standard potassium chloride solution of known conductivity and adjust the setting until the meter shows that value.

Which samples suit the higher salinity ranges?
Seawater, brackish well water, marine aquarium water and saline soil extracts give readings in ppt and use the upper ranges. Tap and drinking water normally read in the ppm ranges. The meter changes range by itself, so you only need to watch the units on the display.

Why does sample temperature matter for salinity readings?
Salinity comes from conductivity, and conductivity rises with temperature. The meter corrects each reading to the reference temperature you program, using a coefficient adjustable from 0.1 to 4.0%. Samples measured at different temperatures can then be compared fairly.
