At Microval Technologies, we understand that accurate acoustic measurements are essential for health, safety, environmental monitoring, and regulatory compliance. Whether you’re working in audiology, industrial noise monitoring, or sound testing, precise calibration ensures the reliability of your acoustic instruments.
Our trained technicians use traceable sound calibration equipment to perform detailed checks and adjustments, ensuring your devices deliver dependable and repeatable results.
On-Site & In-Lab Calibration
Acoustic equipment is sensitive and must perform consistently in critical applications. We offer both in-lab and on-site calibration services across Pakistan to minimize downtime and ensure your instruments remain compliant with IEC, ISO, and OSHA standards.
Diagnosis, Adjustment & Certification
If we detect deviations during calibration, our team will consult with you before proceeding with any necessary adjustments or repairs. Once corrected, your instrument will be recalibrated and certified, guaranteeing accurate and safe operation.
At Microval Technologies, we are committed to providing acoustic calibration services that meet international standards and deliver confidence in every decibel.
Acoustic Calibration ensures that sound-measuring instruments such as sound level meters, audiometers, microphones, and noise dosimeters are performing accurately and in accordance with international standards. In critical environments like hospitals, laboratories, environmental monitoring, and industrial safety, precision in sound measurement is non-negotiable.

For dependable acoustic calibration services, MICRO-VAL is your trusted source across Pakistan. Our acoustic calibration capabilities include equipment used in occupational health, audiology, noise regulation, and building acoustics.
Using advanced calibrators and sound generators, our trained technicians ensure traceable, repeatable, and reliable calibration results. Each device is tested under strict protocols to verify compliance with IEC and ISO standards.
At MICRO-VAL, we focus on accuracy, traceability, and compliance, ensuring your sound measurement devices deliver reliable data when it matters most.
WHY CHOOSE MICROVAL LAB TECHNOLOGIES
Unfortunately though, so few laboratories or text books contain the correct procedures for calibration of volumetrics. Everyone should know to take into account temperature variations on the water and glassware, but how many people take into account the different shrinkage rates between Borosilicate glass and Soda Lime glass. With Borosilicate’s tighter molecular structure than Soda Lime glass it is less responsive to changes in temperature resulting in minimal thermal expansion which needs to be taken into consideration when testing calibrations. So how do I tell them apart I hear you ask. As a general rule Soda Lime glass is labelled in amber stain, while Borosilicate glass not being able to be stained successfully with conventional amber staining techniques, will be labelled in white or blue ink. Some brands such as Duran are a trade name for Borosilicate glass 3.3, so these will all be in Borosilicate.
Calibration procedures are also influenced by air pressure and temperature at the time of reading, regardless of what type of glass you are testing. By measuring a barometer reading and calculating the air temperature the results may be used in an “Air Pressure And Temperature Correction Table” to obtain a correction figure which is taken into account to obtain a final gravity result to ensure a consistently accurate result is obtained.
We strongly recommend that to comply with good laboratory practice, all Class A volumetric glassware should be check calibrated on receipt. If you consistently find that the glassware falls outside the Class A tolerances for accuracy or delivery time, it should be sent back to your supplier.
For your convenience we at MICRO-VAL have collated all of the relevant procedures and tables from ISO Standards and British Standards We aIso offer a variety of flexible delivery options, including a pick-up and drop-off service, or you can send us your equipment directly.
