Hi Bosean Team,
Could we get the copy certificate for SO2 Gas Detector type BH-90A which declare this product is explosion proof  : Ex ib IIB T3 Gb?
We had to order 2 ea of this SO2 Gas detector and because we want to use it for rig / site operation we need the explosion proof declaration certificate (COC).
Could we get the password? As we will use local 3rd party here for calibration. 
And also could you advise how much PPM of SO2 Gas which suitable for calibration?Really appreciate for your response & feedback.
Thanks and regards,
