ZO-802A Zirconia Oxygen Analyzer (Reflow Soldering Furnace Specific)Detailed product description：

The ZO-802 zirconia oxygen analyzer is a new type of analytical instrument developed using the latest zirconia detection technology and microcomputer technology. It can be used for continuous automatic analysis of oxygen content in air separation nitrogen production, chemical processes, glass, and building materials. It can also be used for measuring oxygen content in protective atmospheres of high-temperature sintering furnaces such as protective gases and magnetic materials in the electronics industry. The instruments designed specifically for reflow soldering furnaces and wave soldering furnaces are equipped with built-in sampling air pumps, external dedicated filters, and sampling pipelines.

ZO-802A Zirconia Oxygen Analyzer (for Reflow Soldering Furnace) Features:
High quality zirconia detection components are selected, which have the characteristics of long lifespan and fast response.
Adopting a large screen dot matrix LCD display, it can simultaneously display parameters such as oxygen content, temperature, date, and time.
Adopting a fully Chinese human-machine dialogue menu, the operation is intuitive and convenient.
Adopting a convection diffusion structure reduces the influence of flow rate on the measurement of trace oxygen.
The instrument has four ranges from trace to constant, with automatic range conversion.
The upper and lower limit alarm points can be set arbitrarily within the full range.
Equipped with a paperless recorder function, it automatically records the curve of oxygen concentration changes over time.
It has the function of automatic storage of measurement data, and the storage interval time is set by the user.
Has 0~10 or 4~20ma current signal output.
The instrument is equipped with an imported sampling pump.
The instrument has a standard RS232C communication port, which can be connected to a serial printer and a computer for bidirectional communication.
