What Is the Mains Frequency Meter Used For?
Mains frequency shows how well a supply is being held at its nominal value, and it changes with load on a generator. Fitted into a panel, this meter gives a continuous digital reading for electrical machines labs, where students watch an alternator’s output frequency change with its speed, for diesel generator and inverter test benches, and for switchboards in workshops and polytechnic power labs. Because the reference is crystal-controlled, the reading does not depend on the mains itself for timing.
The meter is wired to the supply being monitored, so it should be installed in a panel by a qualified electrician with the supply switched off. Keep the panel cut-out dry and ventilated.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Your supply voltage and the nominal frequency to be monitored, as the listing does not state the input rating.
- The panel cut-out size you need, so JLab can confirm the cabinet fits.
Frequently Asked Questions
What does the meter display?
The frequency of the mains supply on a three-digit digital display, timed against a crystal-controlled reference.
How accurate is it?
The listing gives 0.05% or 1 digit. Ask JLab to confirm the input voltage range with your quotation.
Can it be mounted in a control panel?
Yes. It has a panel-mounting type cabinet, with its power supply and circuits built on phenolic printed circuit boards.
Who manufactures it?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its Ambala works in Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electrical and digital measuring instruments for teaching and testing labs, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The meter is assembled in the company’s own works instead of being bought from a trader, so colleges, workshops, panel builders, dealers and importers buy factory-direct; each unit is checked visually before packing and repeat orders are handled by the manufacturer. Its tax registration is GSTIN 06AADCJ9848D1ZE and its Legal Entity Identifier is 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example Germany in Western Europe, the Dominican Republic in Central America and the Caribbean, Indonesia in Southeast Asia, Italy in Southern Europe and Vanuatu in Oceania.
