Ankur Speciality Gases & Technologies Pvt Ltd provides you highly accurate calibration gas mixtures with national or international traceability as required. Calibration gas, also known as a calibration gas mixture, is generally a compressed mixture of gases or gaseous components. Calibration gases are used as comparison standards in the calibration of many instruments. They ensure that instruments such as gas analyzers or gas detectors read correctly. Single flammable gas detectors are usually calibrated using a methane gas calibration or isobutane calibration. You must calibrate a single toxic gas detector with the specific single toxic gas it is designed to monitor. Common single-gas calibration gases include carbon monoxide, hydrogen sulfide, and ammonia. Welding and Cutting. Laser Technology. Modified Atmosphere Packaging. Making Glass.
