Digital TDS Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-TM-2196
Jlab Export is a leading Digital TDS Meter Manufacturer,and suppliers in India
Reading TDS directly in ppm and ppt, this mains-powered table meter covers five ranges from 0–200 ppm to 0–1000 ppt on a 3½ digit LED display. Its lowest range resolves 0.1 ppm, which suits RO permeate and drinking water. It uses a platinum dip-type cell, with the cell constant set from the front panel and a Check facility for calibration.

Comparing Waters: Student Lab Exercises
A popular practical compares TDS in tap water, RO water, bottled mineral water and Distilled Water. Students rinse the cell from a Wash Bottle between samples so that one water does not carry over into the next. They rank the samples and discuss why RO and distilled water read lowest.
To check the meter itself, students can evaporate a measured volume of tap water to dryness and weigh the residue. They then compare that figure with the meter reading. The Testing Drinking Water kit adds strip tests for hardness, alkalinity and chlorine on the same samples.
Frequently Asked Questions
Does a low TDS reading mean water is safe to drink?
No. The meter estimates dissolved ionic solids from conductivity. It does not detect bacteria, most organic compounds or uncharged substances such as sugar. Use it to track dissolved salts, for example to see whether an RO unit is still removing them.
Which range will RO, tap and bottled water fall in?
RO and distilled water read in the lowest range, 0 to 200 ppm, where the meter resolves 0.1 ppm. Tap and mineral waters usually sit in the same range or the next one up. Salty process water and brines move into the ppt ranges, up to 1000 ppt.
Why is the temperature set by hand on this model?
This model uses manual temperature compensation from 0 to 50 °C. Read the sample with a thermometer and set that value before measuring, because the conductivity behind each TDS figure rises as water warms. Let samples reach room temperature if you want to compare them directly.
How does it differ from the portable Digital TDS Meter?
This one is a 230 V table model with an LED display, five ranges up to 1000 ppt and 0.1 ppm resolution. The portable Digital TDS Meter runs on a 9 V battery, has an LCD and a carrying case, and reads to 1 ppm.
