ZO-802 Zirconia Oxygen AnalyzerDetailed product description：

Characteristics of ZO-802 Zirconia Oxygen Analyzer:

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 eight ranges from trace to constant, with automatic range conversion.
The upper and lower limit alarm points can be set arbitrarily within the full range.
The instrument has an automatic storage function for measurement data, and the storage interval time is set by the user.
Equipped with a paperless recorder function, it automatically records the curve of oxygen concentration changes over time.
Has 0~10 or 4~20mA current signal output.
The instrument has a standard RS232C communication port, which can be connected to a serial printer or achieve bidirectional communication with a computer.
The instrument adopts a small flow meter, making it more compact.
