Whenever – No chemical reagents to prepare – ready for immediate use.

Wherever – Light weight and compact, Kitagawa’s system is easy to carry in the most difficult situations.

Whoever  – The system is simple and straightforward to operate and no academic knowledge is required – all personnel can operate it with ease.

Speedy – An accurate reading can be obtained within a few minutes and many sample points can be tested in a very short period of time. This gives it a major advantage over the competitive bellow type pumps that are open to user error and take far longer in sampling time.

Safety  – As no electricity or heat is required, tests can be taken without risk of explosion, even in the most flammable of atmospheres.

Low Cost  – The pump and detector tubes offer a low cost solution to gas detection. There are no costly repair bills or spares (a simple leak test can be performed by any user). No expensive calibration is required. One pump can be used repeatedly to sample the vast spectrum of both popular and specialist gases and vapours.

The ORIGINAL Gas Detector Tube System 

KOMYO first developed the pioneering KITAGAWA Gas Detection Tube System in 1947. With Komyo’s experience and state-of-the-art technology, the gas detector tube system has been continuously developed to ensure maximisation of accuracy, operation and safety in the field of gas detection and analysis.

The Kitagawa System is an accurate and cost effective spot gas detector sampling system, offering over 300 gas detector tubes, from Ammonia to Xylene. This System is renowned for its excellent features in the analysis of gas concentration and is widely used throughout the world across a vast array of industries and applications.

Global Certification & Approvals

The Kitagawa Gas Detector Tube sampling system is certified in accordance with the European Standard, EN 1231 (Workplace Atmospheres – Short Term Detector Tube Measurement Systems – Requirements and Test Methods), by the Berufsgenossenschaftliches Institut für Arbeitsschutz (BIA), Germany.

The Kitagawa Gas Detector Tube System pump and tubes are additionally certified by the American Safety Equipment Institute (SEI) in accordance with strict American National Standards ANSI/ISEA 102-1990 (for Gas Detector Tube Unit – Short Term Type for Toxic Gases and Vapours in Working Environments).
