Low-Temperature Oil-Filled Pressure Gauge
The low-temperature version of the multi-refrigerant gauge, the 191# keeps the same R22/R134a/R404A/R407C pressure–temperature scale but extends the medium range down to −40 °C for freezers and cold storage. It shares the 2.5" full stainless flanged case, wide beryllium-bronze tube and oil-damped, vibration-proof movement.

Multi-Refrigerant Oil-Filled Pressure Gauge
A glycerin-filled, vibration-damped refrigeration pressure gauge built for freezers, cold-rooms and air-conditioning units. One gauge reads multiple refrigerants — R22, R134a, R404A and R407C — on a combined pressure–temperature scale, with a 2.5" full stainless case, wide beryllium-bronze Bourdon tube and a flanged edge for axial panel mounting.
R410A Oil-Filled Pressure Gauge
Purpose-built for high-pressure R410A systems, this oil-filled gauge uses an imported high-precision pressure movement with a micro-adjustable zero and a special over-pressure limiting device. The 2.5" stainless, flanged axial gauge covers −40 °C to +120 °C, suiting modern high-pressure split and VRF air-conditioning equipment.
