Calibration Scope
What We Calibrate
All calibrations are NABL-accredited, traceable to NPL India, and performed per BIPM/JCGM GUM methodology. On-site or lab-based — your choice.
Patient Monitoring Equipment
Multi-parameter monitors, ECG machines, pulse oximeters, SpO₂ sensors, NIBP modules, and temperature probes — traceable calibration with full uncertainty budget.
ECG
SpO₂
NIBP
Infusion & Syringe Pumps
Flow rate accuracy verification, occlusion pressure testing, and alarm function validation. On-site calibration prevents workflow interruption in ICU and OT settings.
Flow Rate
Occlusion
Alarms
Anaesthesia & Ventilators
Tidal volume, pressure, flow and FiO₂ verification. Gas analyser and O₂ analyser calibration. Breathing circuit testing for anaesthesia workstations and ICU ventilators.
Tidal Volume
FiO₂
Electrotechnical Instruments
Electrical safety analysers (IEC 62353), power quality meters, digital multimeters, LCR meters, and oscilloscopes — all traceable to NPL/BIPM standards.
Safety Tester
DMM
Defibrillators & AEDs
Energy output verification, synchronisation accuracy, pacemaker output, and patient leakage current testing for defibrillators and automated external defibrillators.
