Calibration unit for Rousemont sensors

Calibration unit for Rousemont sensors

(OP)
Please help me choose what calibration unit better buy. Dpi325 or Dpi 620.
I work for Gas industry. Mostly i need to calibrate Rosemount sensors, model 1151 and 3051 with ranges 0.....150 in H20, 0.....500 in H2O, 0....60 psi, 0...1500 psi, 0....2000 psi.
Maybe is some other pneumatic calibration units with built-in cylinder for nitrogen.
Maybe anybody have experience work with Wally box 65-2000II or BetGage 330 prior to small ranges 0....500 in H2O.
Just now i use Walley&tiernan 65-125 for range 0...60 psi and Condec UPC5100 for range 0....2000 psi.
I need to displace this two units with the latest developments in technology.

RE: Calibration unit for Rousemont sensors

Druck make a really good calibrator.
For the low ranges (in the workshop) I still prefer a mercury manometer with a Moore regulator.
Wally boxes were great but quite fragile.
Good Luck
