Volume Change Apparatus
Volume Change Apparatus (Product Code: SLE/CE/19) is a mould-and-comparator set used to measure the change in length of cement mortar and concrete specimens as they shrink or expand, in materials testing laboratories. It combines a specimen mould with base plate and four reference pins with a length comparator frame whose dial gauge reads 0.002 mm over 5 mm. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes the set as the OEM at its own factory in Ambala, India.

What Is the Volume Change Apparatus Used For?
Volume change in hardened cement mortar and concrete is usually tracked as a change in specimen length. The reference pins are set into the ends of the specimen when it is cast, giving fixed gauge points; after demoulding, the specimen is placed in the comparator frame and its length is read on the dial gauge, then read again at intervals as it dries, cures or is exposed to test conditions.
Zero the comparator with the stainless reference bar before each set of readings. The insulated grip matters: holding the bar or specimen with bare hands warms it and adds error at the 0.002 mm level. Keep the comparator in the same room as the specimens. Buyers comparing lab instruments manufacturers in India will find the complete set saves matching a mould and comparator from different sources.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Volume Change Apparatus. The mould, pins, comparator frame and reference bar are supplied as one set from the company's own licensed factory at Saha, Ambala, Haryana, India, so the parts are matched from the start. For institutional and tender buyers who need vendor details, the company is registered under GSTIN 06AAECJ8618A1ZT and holds LEI 3358004HRD1JIVXKYX49.

Frequently Asked Questions
What does the Volume Change Apparatus measure?
The Volume Change Apparatus measures the change in length of cement mortar or concrete specimens over time, which indicates shrinkage or expansion. Readings are taken between reference pins in the specimen using a length comparator frame and dial gauge.
What is included in the Volume Change Apparatus set?
The Volume Change Apparatus comprises one mould complete with base plate, four reference pins, one length comparator frame, one stainless reference bar with insulated grip and one dial gauge of 0.002 mm × 5 mm.
What is the resolution of the Volume Change Apparatus dial gauge?
The dial gauge supplied with the Volume Change Apparatus reads 0.002 mm and has a travel of 5 mm. That resolution is fine enough to follow small shrinkage or expansion movements in mortar and concrete specimens.
What gauge length does the Volume Change Apparatus mould have?
The effective gauge length of the Volume Change Apparatus mould is not stated in this listing. Tell us the test method or specimen size you work to through the contact page, and the gauge length will be confirmed in writing with your quotation.
Who manufactures the Volume Change Apparatus?
The Volume Change Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. The company handles quotations, repeat supply and spare-part enquiries itself.
Is a calibration certificate available for the Volume Change Apparatus dial gauge?
Calibration-certificate availability for the Volume Change Apparatus dial gauge should be discussed with us before ordering. Mention the requirement in your enquiry through the contact page so it can be addressed in the quotation.
