8 Best Calibration Services in Singapore (2026)

Calibration keeps measuring instruments such as thermometers, gauges, torque wrenches and weighing scales giving readings you can trust, and many factories, labs, clinics, kitchens and workshops need it done regularly. This page lists eight Singapore calibration firms that describe their services on their own websites, from temperature and pressure to acoustics, weighing and force. Each write-up summarises what the firm says it offers and where it is based, and statements about accreditation are the firms' own claims, not LocalRank's. Use the list to shortlist providers by instrument type, then use the guide below to ask about scope, on-site visits and certificates before you request a quote.

Micro Precision Calibration runs a Singapore laboratory in the Ang Mo Kio industrial area, part of a wider international calibration group. Its Singapore page lists laboratory and on-site calibration across electrical, optical, mechanical, thermodynamic, RF and microwave, and semiconductor categories. Instruments it names include multimeters, oscilloscopes, power supplies, pressure gauges, torque wrenches, flow meters and infrared thermometers, and it also mentions repair, equipment sales and rental. The site states the lab is ISO 9001 verified and ISO/IEC 17025 accredited, and mentions optional ANSI/NCSL Z540 compliance; LocalRank has not checked the scope behind either statement. Quotes are requested through an online form or by contacting the office directly. A reasonable pick for electronics and test-equipment fleets that need one supplier for several instrument types.
