Altitude gauge in 3-1/2 in and 4-1/2 in — dual PSI and feet-of-water scale (0–100 PSI / 0–231 ft H2O), steel case, brass socket, 1/4 in NPT low mount, for water-tank level and boiler altitude indication. Configured to order.
Combined boiler pressure and temperature gauge in 2-1/2 in — dual 0–75 PSI and 60–320 °F dial, steel case with chrome-plated ring, 1/4 in NPT center-back mount, for hydronic boilers and heating systems. Configured to order.
4-1/2 in mechanical contractor's test gauge — low-lead brass (2011 Reduction of Lead in Drinking Water Act compliant), precision geared movement with zero-adjust, ±1½-1-1½% of span (ASME Grade A), for plumbing and hydronic commissioning. Configured to order.
Welding and compressed-gas regulator gauges (Models 601, 607, 612, and 618) in 1-1/2, 2, and 2-1/2 in — brass or gold-painted steel case, brass movement. UL 252A recognized on the low-pressure regulated gauges and UL 404 listed on the high-pressure cylinder gauges, for oxygen, acetylene, and inert-gas service. Configured to order.
Corrosion- and weather-resistant utility gauge in 1-1/2 in and 2 in — gray ABS case and ring, brass wetted parts, ±3-2-3% of span. Low- and center-back-mount NPT for outdoor, washdown, and mildly corrosive environments. Configured to order.
3-1/2 in fire-sprinkler gauge — FM approved and UL listed, with water (0–300 PSI), air (0–80 PSI retarded to 250), or air/water dials for wet and dry fire-protection risers. Brass, 1/4 in NPT low mount. Configured to order.
HVAC/R manifold test gauge in 2-1/2 in — red (P1785) or blue (CR1785) case with refrigerant pressure/temperature scales for R-12/R-22/R-502, R-134A, and R-410A. Brass, 1/8 in NPT low mount for service manifolds. Configured to order.
2 in dial tire pressure gauge — brass- or chrome-plated steel case, phosphor-bronze Bourdon tube, straight tire chuck, 0–60 PSI (other ranges available). A protective rubber boot is available separately. Configured to order.
