Physical Balance Manufacturer,Supplier and Exporter in India

Physical Balance (Product Code: SLE/LB/08) is a general purpose beam balance used by students to find mass and specific gravity in school and college physics practicals. It takes up to 250 g at 2 mg sensitivity, and its hangers carry double hooks so an object can be weighed while suspended in water. It is made by OEM manufacturer Jain Scientific Equipments Pvt Ltd (ScienceLab) at its own factory in Ambala, as part of its physics lab equipment in India.

Specifications

What Is the Physical Balance Used For?

Physics students use this balance to find the mass of solids and, most often, to determine specific gravity (relative density). The object is first weighed in air from the pan; it is then hung by a thread from the lower hook of the double-hook hanger so that it sits fully immersed in a beaker of water placed beneath, and weighed again. The loss in weight gives the upthrust, and the ratio of the two readings gives the specific gravity — a classic Archimedes’ principle experiment for mechanics lab equipment in India.

Before each practical, adjust the levelling screws until the plumb line hangs centrally, then use the balancing nuts to bring the empty beam to zero. Load masses with forceps, starting with the largest, and let the pointer swing evenly on both sides of centre rather than waiting for it to stop. Detach and wipe the nickel plated brass pans after use, and store the balance with its case closed.

OEM Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited sells the Physical Balance, and the company is its OEM (original equipment manufacturer). The cast alloy beam, nickel plated brass pans and polished wooden case are brought together at the company’s own licensed factory at Saha, Ambala, Haryana, India. The balance goes factory-direct to schools, colleges, dealers and importers; read our company profile to learn more.

Frequently Asked Questions

Can the Physical Balance be used for specific gravity experiments?
Yes. The Physical Balance is suited to specific gravity experiments because its hangers have double hooks, so an object can hang below the pan and be weighed while fully immersed in a beaker of water.

How do I level the Physical Balance?
Level the Physical Balance by turning its levelling screws until the plumb line hangs centrally, then use the balancing nuts on the cast alloy beam to bring the empty beam to zero before any weighing begins.

What are the capacity and sensitivity of the Physical Balance?
The Physical Balance has a capacity of 250 g and a sensitivity of 2 mg, which covers the mass and specific gravity practicals commonly set for school and undergraduate physics students.

Are masses supplied with the Physical Balance?
Masses are not listed with the Physical Balance. The matching Physical Balance Mass Set, with chrome plated brass masses, forceps and light metal fractional weights in a lidded case, is available separately.

How is the Physical Balance different from a chemical balance?
The Physical Balance takes up to 250 g at 2 mg sensitivity and has double-hook hangers for specific gravity work, while our Chemical Balance is more sensitive and has a rider scale for finer chemistry weighing.

Who manufactures the Physical Balance?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Physical Balance (SLE/LB/08). It is made at the company’s own licensed factory at Saha, Ambala, Haryana, India, and quoted factory-direct to schools, colleges and distributors.

Is a calibration certificate available for the Physical Balance?
A calibration certificate is not listed for the Physical Balance. If your lab needs calibration documentation, discuss it with our team through the contact page before ordering so we can advise what is possible.
