Gas detection
An uncalibrated monitor is worse than no monitor at all.
A drifting sensor reads safe in an atmosphere that isn't. Zokal calibrates, bump tests, repairs and certifies portable and fixed gas detection so entry decisions rest on real numbers.
Authorised service centre with traceable calibration gas and documented test results.
