Features:

Acid sensing component that changes color when exposed to acid with a pH ≤ 3.0.
Pressure ranges available up to 10,000 psi.
Gauge welded to seal for tamper-proof design.
Options for Halocarbon® fill for oxidizing acids and custom dials.
Available with Silicone-free PLUS!™ Performance.

Key Benefits:

Visual indication of leaking process media.
Dual containment for enhanced safety.

Specifications:

Accuracy: ±1.0% of span for 1259 and 1279, ±1.5% for T6500.
Process Connection Size: 1/2 NPT.
Case Style: Solid front with pressure relief back.
Weather Protection: Hermetically sealed, IP66 rated.
Pressure Rating: Vacuum to 1,500 psi standard, up to 10,000 psi optional.

Materials:

Wetted Components: Diaphragm made of 316L SS, Hastelloy® C-276, or Monel®.
Non-Wetted Components: Top housing made of 316L SS or Monel®.

Ordering Information: The document provides a detailed ordering code system, specifying options for dial size, assembly type, case, material, process connection size, system fill fluid, and additional options like high-pressure seals and case color.

Pressure Ranges: The document includes tables for pressure ranges in various units (psi, bar, kPa, mPa, kg/cm²) for both 1259/1279 and T6500 models.

Dimensions: Detailed dimensions are provided for the 1259/510 and 1279/510 Seal Assemblies, as well as for the 1279 or 1259/DF Seal Assembly, with measurements in both inches and millimeters.
