Could someone recommend a calibration instrument that can be used to calibrate pressure and differential pressure transmitters, covering both large and small measurement ranges?
Our company purchased a pressure calibrator model TL-801; its range is from -95 KPA to 2.5 MPA. It costs around 10,000 yuan or so… I think it’s pretty good.
Beijing Constar CST 2003 intelligent digital pressure calibrator, with a pressure range of -100 kPa to 250 MPa.

The Drucker DPI610 and DPI615 are both quite good
Bemex in Finland offers an excellent cost-performance ratio.
We’re using the one from Beijing Constar, and it works pretty well~~~
