The 20BTG-250-4-1/2 B-Series Temperature Murphygage is a 2" dial, diaphragm-actuated temperature-indicating gauge with a temperature range of 130-250°F and a 4 foot capillary length.
The instrument is a high quality, diaphragm-actuated indicating gauge. With the same heavy-duty design as the standard 20 series Swichgage instrument, the B-gauge is more compact and is the optimum instrument for gauge-only applications. B-Series gauges have a high-impact polycarbonate lens, sturdy steel case, and a polished, low-profile stainless steel bezel.
