A purgemeter for measuring micro flow rates of gases

P-880

Purgemeter
OUTLINE
The P-880 is an area purgemeter for measuring micro flow rates ofgases. This purgemeter is equipped with an improved valve to accurately
control the flow rate. The P-880 is ideal for measuring and controlling
micro flow rates.

FEATURES❏ Micro flow rate measurement
Can measure flow rates from 0.15 to 1.5 mL/min (nor) to 6 to 60 L/min (nor)❏ Easy flow rate control
Can control flow rates accurately. The optimum valve will be provided
for your specification of inlet and outlet pressures.
❏ Selectable face-to-face dimensions
Three face-to-face dimensions (115 mm, 130 mm, and 145 mm) areavailable for various applications.
❏ Compact, lightweight design
3 mm smaller in width and half the weight compared with the P-810.
