technical indicators

Zirconia oxygen analyzer (constant temperature wall mounted)LCD display/Oxygen analyzer model: DP-300

The DP-300 zirconia oxygen analyzer (constant temperature type) consists of two parts: a converter and a zirconia probe. It does not require sampling equipment or auxiliary equipment. The oxygen probe is directly inserted into the furnace or flue, which can quickly and accurately reflect the instantaneous oxygen content during combustion in the furnace, and output an electrical signal proportional to the oxygen content.
