HZQW_JPB-70A pen type intelligent dissolved oxygen analyzer (hereinafter referred to as the instrument), mainly for the convenience of users to carry to the site operation design. The instrument can be divided into two parts: sensor and electronic unit. The sensor adopts polarographic coated dissolved oxygen electrode. The electronic unit is composed of high integrated circuits. The instrument adopts the lattice liquid crystal display, which can show the dissolved oxygen value and temperature.
