ZDO-I,ZDO-III Thermocouple vacuum gaugeDetailed product description：

Characteristics and Applications of Thermocouple Vacuum Gauge:
Thermocouple vacuum gauge (400-10-1 Pa)
The thermocouple vacuum gauge adopts a new type of short wire thermocouple gauge tube, which has the advantages of fast reaction speed (small opening for 3 seconds), long service life, and strong anti pollution ability. This instrument adopts popular microcontroller technology and linearizes the regulation of non wires; And it has added functions such as computer communication interfaces, making the instrument's readings intuitive, accurate, flexible in control and communication, convenient, and reliable, providing a means for the digital display and control automation of rough and low vacuum measurement in vacuum systems and equipment to become a reality.
LED digital display, with a display format of two digit coefficients and one digit index.  
Microcomputer automatically corrects and regulates nonlinearity.  
Optoelectronic isolation, strong anti-interference ability.
PVC colored panel, with a beautiful and elegant appearance.  
Dual control, relay output, point control or area control, control points can be set arbitrarily and have power failure protection and memory function.
