Jockey with Insulated Handle (Single)
Jockey with Insulated Handle (Single) (Product Code: SLE/PHY/80) is a hand-held contact probe used to find the balance point on the wire of a Wheatstone bridge or potentiometer in physics practicals. It is 100 mm long overall, with an insulated handle, a plated brass contact and a 4 mm plug terminal for connection to the circuit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Insulated Jockey Used For?
In bridge and potentiometer experiments the jockey is the moving contact: the student touches it onto the resistance wire at different points until the galvanometer shows no deflection, then reads the balancing length from the scale. The 4 mm plug terminal pushes into a lead or socket, so the jockey links the wire to the galvanometer without a loose clip.
The insulated handle keeps fingers off the circuit and stops hand contact from disturbing the reading, which matters in any meter bridge lab in India where many students share the same apparatus. Tap the brass contact gently and lift it between trials rather than sliding it, since a dragged contact scores the wire. Wipe the tip clean if readings start to jump.
What to Specify When Ordering
- Number of jockeys (this listing is for a single jockey)
- The bridges or potentiometers they will be used with, if you also need those quoted
- Whether you prefer this plug-terminal jockey or a pencil (knife-edge) type
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer of this jockey. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, the same factory that makes the bridges and potentiometers it is used with, so labs can match jockeys to their apparatus through one manufacturer. Schools, dealers and importers order factory-direct, and repeat orders for spares are handled by the maker itself. See the company profile for more.

Frequently Asked Questions
How long is the Jockey with Insulated Handle?
The Jockey with Insulated Handle (Single) is 100 mm long overall. That length is easy to hold steady between finger and thumb while tapping the contact onto a bridge or potentiometer wire.
What type of terminal does the jockey have?
The Jockey with Insulated Handle (Single) has a 4 mm plug terminal, which fits standard 4 mm sockets and lead connectors. It connects the jockey to the galvanometer side of the circuit without crocodile clips.
Which apparatus is the Jockey with Insulated Handle used with?
The Jockey with Insulated Handle (Single) is made for Wheatstone bridge and potentiometer work, including metre bridges. It serves as the moving contact that finds the balance point along the resistance wire in these experiments.
Who manufactures the Jockey with Insulated Handle?
The Jockey with Insulated Handle (Single) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and is supplied factory-direct to labs and dealers.
Why does the jockey need an insulated handle?
The insulated handle on the Jockey with Insulated Handle (Single) keeps the user's hand out of the circuit. This prevents body contact from affecting the galvanometer reading and gives a firm, comfortable grip during repeated balance-point measurements.
Can jockeys be ordered as spares in quantity?
Yes, the Jockey with Insulated Handle (Single) can be ordered in quantity as spares for existing bridges and potentiometers. Send the number needed and your delivery location through the enquiry cart or contact page for a quotation from the manufacturer.
