Determine Hydrogen in steel accurately, rapidly and conveniently with LECO's RH-101 & DH-102! • Direct reading to 0.01 ppm • Blanks less than 0.02 ppm • 3-4 minutes analysis time The LECO® RH-101 and DH-102 inert gas extraction technique eliminates undesirable conditions such as interfering gases (oxygen and nitrogen are not released because the sample is heated below its melting point), system outgassing time, significant system blanks, and potential reduction reactions. The LECO® RH-101 determines residual hydrogen in solid samples or samples taken from molten steel. The LECO® DH-102 determines both diffused and residual hydrogen using the new LECO® vacuum sampler (patent pending).
