Engineers who have used what they sell
Calibration, testing and inspection with as-found and as-left values, stated uncertainty and an unbroken traceability chain.

Electrical, temperature and pressure instruments calibrated against traceable references, with as-found and as-left values on every certificate.

Thermographic surveys of switchgear and motors under representative load, with findings ranked by severity and timescale.

Your whole fleet on one calibration schedule, with recall reminders, collection and delivery, and a single annual contract instead of dozens of purchase orders.

Earth resistance, insulation and continuity testing with certified reports for compliance and insurance records.

Infrared survey of switchgear, motors and terminations under representative load, with every anomaly ranked by severity and a recommended timescale.

Annual contract
We hold your asset register, calibrate before each due date and guarantee priority turnaround.

“Certificates that satisfy the auditor.”
Their certificates carry as-found values, which is exactly what our auditor asks for. We stopped having to explain ourselves at every inspection.

Calibration3 min read
Twelve months is a convention, not a rule. The right interval comes from drift, duty and what a wrong reading costs.
