OUTLINE

The P-880 is an area purgemeter for measuring micro flow rates of

gases. 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) are

available for various applications.

❏

Compact, lightweight design

3 mm smaller in width and half the weight compared with the P-810.

MAJOR APPLICATIONS

1. Built-in use for equipment

2. Biotechnology industry

3. Semiconductor-related gas equipment
