Dilution Solution Pressure Gauge, 0-100 PSI, 1/4" Mount

Stainless Steel Pressure Gauge, 0-100 PSI, 2 Inch Face – PG100-SS

The Dilution Solutions PG100-SS is a stainless steel pressure gauge with a 2-inch dial face and 1/4-inch brass NPT bottom-mount threads. It reads 0-100 PSI. Stainless steel construction is specified for NDS installations because grow facilities and irrigation environments are damp to wet, and a standard carbon steel gauge case will corrode over time in these conditions — affecting readability and gauge longevity.

The 2-inch face provides a readable dial without requiring a large gauge body in a compact NDS assembly. Bottom-mount connection means the 1/4-inch brass threaded connection enters from the bottom of the gauge rather than the back, which is the appropriate orientation for tee or branch connections in NDS plumbing where the gauge is mounted upright. The PG100-SS is compatible with Dilution Solutions NDS Starter Kits and Monitor Kits.

Key Features & Benefits

• Stainless Steel Case — Resists corrosion in wet and damp irrigation and grow room environments.
• 0-100 PSI Range — Appropriate range for monitoring inlet and system pressure in NDS installations.
• 2-Inch Dial Face — Readable gauge size for compact NDS assembly mounting locations.
• 1/4-Inch Brass Bottom-Mount — Standard NPT thread size and bottom-mount orientation for tee-mounted gauge installations.
• NDS System Compatible — Designed for use with Dilution Solutions NDS Starter Kits and Monitor Kits.
• Extended Service Life — Stainless construction extends gauge life compared to carbon steel alternatives in damp conditions.

Who Should Use This Gauge

The PG100-SS is the correct Dilution Solutions gauge for NDS system installations requiring system pressure monitoring in a wet or damp environment. It replaces a corroded or failed gauge in an existing NDS installation, or serves as a spare for facilities stocking maintenance parts.

Why Stainless Steel Matters for Grow Facility Pressure Gauges

Standard pressure gauges use a carbon steel case and internals to keep manufacturing costs low. In dry indoor environments, these perform well for years. In grow facilities, however, the combination of high ambient humidity, occasional water spray, and the presence of liquid fertilizers and nutrients creates conditions where carbon steel corrodes relatively quickly. Corrosion on the gauge face and bezel affects readability, while internal corrosion can cause the needle to seize or read inaccurately. Stainless steel cases eliminate the external corrosion issue and extend the gauge's readable service life in these conditions.

Frequently Asked Questions

What is the pressure range?

The PG100-SS reads 0-100 PSI. That range covers typical inlet and system pressure monitoring points in Dilution Solutions NDS installations.

What is the dial face size?

The gauge has a 2-inch diameter dial face. That size keeps the gauge readable while staying compact enough for tee-mounted installations in a crowded NDS assembly.

What thread type and size does it have?

1/4-inch NPT brass threads in a bottom-mount configuration. Bottom-mount orientation is what lets the gauge read correctly when installed upright on a branch tee.

When should I replace an existing gauge with the PG100-SS?

Replace an existing gauge when it shows visible corrosion on the case or bezel, or when the needle sticks or reads inconsistently. Stainless construction on the PG100-SS is specifically meant to avoid that failure mode going forward in damp grow-room conditions.

Is this compatible with Dilution Solutions NDS kits?

Yes, the PG100-SS is designed for use with Dilution Solutions NDS Starter Kits and Monitor Kits. Its bottom-mount 1/4-inch NPT thread matches the tee connections used in those kits.
