According to regulations, all ships should have the standard set of calibration gases for portable gas detectors. At times it is difficult to be supplied in short notice and the safety of the crew is jeopardized.

Our Calibration gas ShipCalas is available for standard shipboard requirements to overcome the delivery uncertainty in Indian ports

Accuracy & traceability:

We offer certified gas standards which provides the ultimate in accuracy and traceability. We can provide custom gas mixtures as well.

These multi-component gas mixtures which are a part of wide range of specialty gases are available in a wide range of concentrations upto ppb levels. The certification confirms their suitability for demanding applications which require the highest levels of accuracy.
