Digital Salinity Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-SM-2200
Jlab Export is a leading Digital Salinity Meter Manufacturer,and suppliers in India
This bench meter reads the salt content of water and soil extracts in parts per thousand (ppt). It works on three ranges up to 50 ppt and picks the right one by itself. A platinum dip cell does the measuring, and its cell constant can be found automatically with a standard solution. Soil labs, swimming pools and mineral water plants use it to keep a check on dissolved salts.

Lab Exercises with Salt Solutions and Soils
A good first practical is checking the cell constant. Students dip the cell in a standard solution made from Potassium Chloride, run the automatic cell constant function and note the value on the display. Next they make up salt solutions of rising strength from Sodium Chloride, each in a Beaker 250 ml. Reading them in turn gives a plot of salinity against the mass of salt dissolved.
For soil work, a class shakes air-dried soil with distilled water, lets it settle and reads the clear extract. Samples from an irrigated field and a garden bed show where soluble salts build up. A water survey runs the same way with tap, well, pond and seawater, rinsing the cell between samples.
Frequently Asked Questions
How does this meter measure salinity?
The platinum dip cell measures how well the sample conducts electricity. Dissolved salts carry that current, so the microcontroller converts the conductance into salinity in ppt and selects the range itself.
Is ppt on this meter the same as PSU?
For teaching work it is close enough. PSU belongs to the practical salinity scale, which is defined from conductivity, and its values come out very close to parts per thousand of dissolved salt. This meter shows salinity in ppt.
Why do I have to set the temperature by hand?
A salt solution conducts better as it warms, so the same water reads higher when it is warm. This model has manual compensation from 0 to 50 °C. Measure the sample with a thermometer and set that temperature on the meter before you read.
Which range will seawater or a soil extract fall in?
The meter chooses for you. Low-salt water such as tap or well water reads on the 0–2.000 ppt range. Brackish water and strong soil extracts move up to 0–20.00 ppt, and seawater-strength samples read on the 0–50.0 ppt range.
How does it compare with a refractometer?
A refractometer reads salinity from how strongly a drop of water bends light. This meter reads conductivity through its platinum cell and picks its range itself, so it also suits weak soil extracts and long series of samples. Check either one against a known standard.
