Product Description 
 Outburst prevention instrument standard calibrator (hereinafter referred to as the "calibrator" ﹞ applies to the pressure sensing element, do the inspection of the various models of anti sudden instrument of detection probe calibration. Coal mine production conditions, anti- sudden instrument site were seriously damaged during use, the need for regular testing, calibration and design can also be applied in outburst prevention equipment manufacturers in the production process and product delivery inspection.
