Zoro Select Altitude Pressure Gauge

This Zoro Select altitude pressure gauge measures system pressure from 0 to 35 psi with a stated accuracy of +/- 1.0 percent. It features a 4 1/2 inch dial housed in a stainless steel case with a plastic lens. The instrument uses a copper sensor and copper socket with a 1/4 inch male NPT bottom connection. It operates across a process temperature range of -40 to 140 degrees Fahrenheit.

Suitable for hydronic

This gauge suits technicians monitoring boiler or hydronic system pressure where an altitude reading is required. The stainless steel case and copper wetted parts provide compatibility with typical water and air media. It is not panel-mountable, so installers needing a flush panel fit should look at a different design. Buyers requiring a hazardous location rating or a specific IP or NEMA enclosure rating will need an alternative model.

Accuracy of +/- 1.0 percent full scale

The +/- 1.0 percent full-scale accuracy specification is the primary figure that determines if this gauge meets your measurement tolerance requirements. Verify this precision level against your system documentation or quality standards before purchase. The 0 to 35 psi range and 1/4 inch NPT process connection must also match your existing port and expected operating pressure.

Questions about this item

Will the 1/4 in NPT connection fit my existing copper piping without adapters?

The gauge has a male 1/4 in NPT bottom connection and copper socket, so it threads directly into a matching female NPT fitting on copper pipe.

How do I verify the gauge reads correctly once installed?

Apply a known pressure up to 35 psi; the needle should stay within +/- 1.0 percent of the reference value across the 4 1/2 in dial.

Does the box include any sealant or mounting hardware for the 1/4 in NPT thread?

The gauge ships alone; thread sealant and any panel-mount hardware must be purchased separately.
