Length Gauge Manufacturer,Supplier and Exporter in India
Product Code : EL-M-8889
Jlab Export is a leading Length Gauge Manufacturer,and suppliers in India
Length Gauge (code EL-M-8889) is an aggregate length gauge for determining the elongation index of aggregate, built from steel studs mounted vertically on a hardwood base. Particles count as elongated when their length is more than 1.8 times their normal size, and the gap between the studs lets each particle be checked by hand. JLab manufactures the gauge in Ambala, India.

What Is the Aggregate Length Gauge Used For?
Highway, concrete and materials testing laboratories use it to judge the shape of coarse aggregate, because elongated particles affect the workability and strength of concrete and the stability of road layers. The sample is first sieved into size fractions; each particle is then tried lengthwise between the studs set for its fraction, and those that will not pass are collected and weighed as elongated. Keep the wooden base dry and wipe the studs clean after use.
Frequently Asked Questions
What is the elongation index?
It is the proportion by weight of a coarse aggregate sample made up of elongated particles, those longer than 1.8 times their normal size, expressed as a percentage.
What is the gauge made of?
Steel studs are mounted vertically on a hardwood base, so the gauge sits steadily on the bench while particles are tested.
Who uses a length gauge?
Concrete and highway materials laboratories, quarries checking the shape of their aggregate, and civil engineering colleges teaching aggregate testing.
Who manufactures the Length Gauge?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it in Ambala, Haryana, as part of its aggregate and cement testing apparatus.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a company incorporated in 2017 with its works on Hargolal Road, Ambala. Buying the gauge direct from the maker lets colleges and testing laboratories add matching apparatus, such as flasks and moulds for aggregate and cement work, to the same factory order. JLab exports worldwide, including to Sudan in North Africa, Bahrain in the Middle East, Myanmar in Southeast Asia and Ireland in Northern Europe.
