Model:JHH1-CTGD-Ⅱ
Overview
Now, China's coal industry is in-depth study, lasting Publicizing (AQ1029-2007) "coal mine safety monitoring system and instrumentation use management practices", in strict accordance with the provisions and requirements of the standard equipment, high standards of Coal Mine Safety Monitoring System and detection equipment,and do a good job seriously and positively related to management, installation, maintenance, adjustment and other aspects of work.AQ1029-2007 Section 8.3.2 states: "The security monitoring equipment and overhaul before use, you must use the specification requirements by product testing, adjust pass, and run in to the interview can only go down 24 ~ 48h." This provision,coal mine safety monitoring system for ensuring the well run, and thus indirectly protect the normal coal mine production safety is important; order to make this provision to be successfully implemented, the company successfully developed the scientific and technological personnel JHH1-CTGD-Ⅱ type gas detector integrated calibrationTaiwan, the integrated verification platform for various small and medium sized mines in China, can easily and quickly adjusted, test the existing coal mine safety monitoring system in a variety of mine detection sensors and instruments.During the trial in the respective mine got good results, we sincerely welcome the experts, leaders and colleagues on the introduction of continuous improvement, sound advice and recommendations to help us to improve the calibrator more in line with mine siteactual needs and jointly make contributions to mine Safety and Health.
