They need to be imported; domestic ones do not meet the requirements. The specifications are as follows: 1. Digital pressure gauge: Medium: steam, pure gases； 1/4VCR internal thread connection ； Pressure range: 0.1 Pa–1,000,000 Pa; display unit: Pa. The displayed values must have three decimal places (0.001), with an accuracy of 0.1%. Medium temperature: 100°C. 2. Digital pressure gauge: Medium: steam, pure gases ； 1/4VCR internal thread connection ； Pressure range: 0.1 Pa–5,000,000 Pa; display unit: Pa. The displayed values must have three decimal places (0.001), with an accuracy of 0.1%. Medium temperature: 100°C. Currently, neither SWAGELOK nor HOKE nor WIKA is capable of handling this. Are there any other brands you can recommend? Thank you!
High-purity digital pressure gauge. For high-purity applications, digital pressure gauges are easy to understand when they are separate; but what about when they are combined? How should that be understood?
Three decimal places refer to a representation like 0.001. 0.1% is the accuracy of the pressure gauge; it was my description that was incorrect. I’m sorry for that, please forgive me!
Many domestic instruments can meet the requirements stated by the poster; unless what’s meant is to display the value as 1,000,000.000, with three zeros added after the unit ‘pa’. Is the poster a beginner who is following instructions mechanically, thereby misinterpreting the intentions of the designers or managers?
It seems to be a question from an amateur.
Hello, I just asked my colleague as well, and they said it was the end user who made this request. To be honest, I really don’t know much about digital pressure gauges; all I can do now is pass on the information that others have given me to my colleague. Thank you!
It’s the FLUCK 700G series; it has a precision of 0.05%, a maximum range of 300 PSI, and the unit can be adjusted as desired. However, its price is not cheap.
