Model: 8270A Modular High-Pressure Calibrators
Fluke 8270A Modular High-Pressure Calibrators provide the accurate result that you are looking for.
A pressure range 100 times smaller than the full scale will meet the control specifications without reducing supply pressure. For example, an 8370A with a 70 MPa (10 000 psi) high range module and a 700 kPa (100 psi) low range module will be able to control pressures below 700 kPa (100 psi) to within ±0.014 kPa (0.002 psi) without reducing the supply pressure.
Flexible configuration options of Fluke modular high-pressure calibrators
The 8270A and 8370A are modular systems that can be configured with up to five measurement modules at the same time, so they can handle high pressure, low pressure, and everything in between. Three families of modules provide three levels of performance that let you set up a system matching your needs for accuracy and value.
So, surely you can now depend on the rugged and reliable Fluke Modular High-Pressure Calibrators that always provide the value. Quick buy now from Tools Bangladesh.
