Hand Held Refractometer Manufacturer,Supplier and Exporter in India
Product Code : EL-GLE-13237
Jlab Export is a leading Hand Held Refractometer Manufacturer,and suppliers in India
Hand Held Refractometer (code EL-GLE-13237) is a hand-held optical instrument, model JL229, that reads the salt content of a liquid in parts per thousand (0–100 ppt) and as specific gravity. Food plants use it to control brines, sauces and diluted concentrates by measurement instead of by taste. JLab manufactures this salinity refractometer in Ambala, India.

Two Scales: Food Brines and Marine Aquaria
The ppt scale suits food processing, where a recipe fixes how much salt a brine, sauce or mixture should carry. One drop gives the figure, so a batch or a diluted concentrate can be corrected before it moves on, rather than judged by tasting.
The specific gravity scale serves marine aquaria, where the water is held between 1.020 and 1.026 for the health of the fish and other animals in it. A reading above that band calls for fresh water; a reading below it calls for more salt.
Taking a Reading
Lift the cover plate, put two or three drops of sample on the prism and close the plate so the liquid spreads into a thin film without bubbles. Point the instrument towards daylight, focus the eyepiece and read the scale where the light and dark fields meet. Rinse the prism with clean water and dry it after each sample, because salt left to dry on the glass blurs the next reading.
Other Ways to Measure Dissolved Content
- Hand Held Refractometer — the JL245 sugar-scale model, reading 0–32% sugar.
- Hand-Held Refractometer — a Brix model for 45–82% juices, soft drinks and sauces.
- Nicholson Hydrometer — finds the specific gravity of liquids by flotation instead.
- Conductivity Meter — gives total dissolved solids in ppm from a conductivity reading.
More bench instruments are in General Lab Equipment.
