It has an accuracy of ±1.00%, a pressure range of 0 psi to 300 psi, and uses Halocarbon as the seal fill liquid with no gauge case liquid. The gauge wetted parts are stainless steel, and the seal lower housing material is Hastelloy C-276.

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 ASHCROFT pressure gauge with diaphragm seal used for?

This ASHCROFT gauge measures pressure from 0 psi to 300 psi in corrosive or viscous media. The Hastelloy C-276 Mini-Seal and Halocarbon fill isolate the gauge from process fluids, making it suitable for chemical, petrochemical, and pharmaceutical applications where stainless steel wetted parts are required.

What are the specifications of the ASHCROFT 451259SD04L/50312HH04TXCF300#?

This ASHCROFT gauge has a 4 1/2 in dial, bottom connection, ±1.00% accuracy, and a 0 psi to 300 psi range. It uses Halocarbon seal fill, no gauge case liquid, stainless steel wetted parts, and a Hastelloy C-276 seal lower housing. The model is 1259/311-312.

Where to buy the ASHCROFT pressure gauge with diaphragm seal worldwide?
