ZO-801S Zirconia Oxygen Analyzer (for sulfuric acid)Detailed product description：

ZO-801S zirconia oxygen analyzer (sulfuric acid specific) is a new type of oxygen measuring instrument developed in recent decades. Due to its simple structure, easy maintenance, fast reaction speed, and wide measurement range, it is widely used in power, metallurgy, heating, building materials, electronics and other departments to analyze the oxygen content of flue gas in various industrial boilers and kilns. The ZO-801S zirconia oxygen analyzer consists of a converter and a detector. The detector adopts a direct insertion probe structure, which does not require a sampling system and can timely reflect the combustion status inside the boiler. If used in conjunction with an automatic control device, it can effectively control the combustion status and is applied in sulfuric acid manufacturing systems.

The main features of ZO-801S zirconia oxygen analyzer (sulfuric acid specific) are:
Large screen LCD display screen
Full Chinese operation menu
Real time clock display
Can be connected to a printer to achieve timed automatic printing
Equipped with timed automatic storage function and the ability to view stored data at any time
Equipped with a paperless recorder function, it automatically records the curve of oxygen concentration changes over time
Equipped with RS232 communication port, it can be connected to a computer to achieve real-time data transmission, data storage, curve trend chart, printing report and other functions
Can set upper and lower limit alarm points, with alarm contact output
Online calibration with available standard gas
Optional output current of 0-10mA or 4-20mA
