Frequently Asked Questions

Is this electrical equipment made by Science Lab Supplies?

Yes. All 57 items in the range are built at the company's factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India. Each product page gives the ratings, materials and scope of supply for that item.

Which items suit Class 12 current electricity practicals?

The meter bridge finds unknown resistance and resistivity, and the potentiometer has a 100 cm scale and jockey. Resistance boxes, rheostats, plug and tapping keys, the post office box and a battery eliminator complete the usual circuit set.

What do the electronics trainers include?

The op-amp trainers carry two 741 op-amps with built-in regulated supplies such as ±15 V. The digital trainers cover logic gates and IC circuits, two of them add a digital voltmeter, and the analog and logic board includes a 10 Hz-100 kHz function generator.

What supply do the load banks need?

It depends on the model: 240 V or 220 V single phase for the 3 kW, 2.5 kW lamp and 12 kW units, 415 V three phase for most inductive and capacitive banks, 240 V three phase for one inductor and 440 V for the 50 kW rheostat.

Can a complete electricity and electronics lab be quoted together?

Yes. Components, trainers, power supplies, meters and load banks from this page can share one offer, together with supplied meters, magnets or power system trainers from the related ranges.

What should an electrical lab quotation request specify?

State the resistance values and current ratings for boxes and rheostats, the voltage and kW or kVAR for load banks, the trainer models and the number of benches. Post the list on the contact page or add the items to the enquiry cart; tenders and OEM orders for electrical benches have their own lab tender page.
