Product Description

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator (MPN 555A-25.0) is a differential pressure indicator with a maximum static pressure of 300 psig. It features an accuracy of ±5% (0-3.5 psid to 0-43 psid), a Buna-N sensor, and a glass-filled nylon housing. The indicator uses three color-coded transition points: green from 0 psid to 11 psid, yellow from 11 psid to 18.5 psid, and red from 18.5 psid to 25.5 psid.

Supplied to the Philippines — compatible with 60 Hz installations. DHL Express delivery to Manila, Quezon City, Cebu, customs and duties handled door-to-door.

Frequently Asked Questions

What is the MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator used for?

This indicator provides a quick visual status of differential pressure in fluid systems, such as filtration or pump applications. The three-color scale (green, yellow, red) allows operators to see at a glance whether pressure is normal, cautionary, or critical, helping prevent equipment damage.

What are the specifications of the MIDWEST INSTRUMENT 555A-25.0?

The MIDWEST INSTRUMENT 555A-25.0 has a maximum static pressure of 300 psig and accuracy of ±5% over ranges from 0-3.5 psid to 0-43 psid. It uses a Buna-N sensor and glass-filled nylon housing. Transition points are 0-11 psid (green), 11-18.5 psid (yellow), and 18.5-25.5 psid (red).
