The SI unit of measure MASS is Kilogram (Kg). We are Calibrating all type of weighing balance and all class weights, PH Meter & TDC Meter also.

Ensuring the accurate pre-production and post-production weights of components used in the manufacture of pharmaceutical and biotechnology products is critical to ensuring product success, efficacy, and safety. Accurate and precise measurement of mass supports the stability, controllability, and repeatability of your sensitive production processes.

GSR Laboratory’s mass calibration service offers high-quality calibration uncertainties, traceable to the International System of Units (SI)

Mail-in calibrations are performed in our 650ft2 Class 10,000 environmentally-controlled mass metrology laboratory, featuring a seismically-isolated mass comparator platform and the highest-quality calibration standards, allowing us to offer minimal measurement uncertainty for your sensitive metrology standards and laboratory instruments.

GSR Laboratory’s metrology laboratory is meticulously maintained at 21-23°C with 40-45% relative humidity, facilitating repeatable and accurate calibration.

Our weight calibration range includes 1mg to 303kg, in accordance with OIML R-111 and ASTM E617

GSR Laboratory provides calibration services that meet GMP requirements. Our reviewed and verified calibration documentation provides the critical information you need to support the accuracy requirements of your standards and instruments. GSR Laboratory’s calibration certificates include both "as found" and "as left" data.

Our normal turn-around times for weights is 2 weeks.

When you choose GSR Laboratory for your mass reference standard and laboratory weight calibration needs, you can enjoy the confidence that comes with knowing that these critical instruments are calibrated with unparalleled accuracy, ensuring precise mass measurement in your own laboratory and production environments.
