The Weiss Series G, inert gas actuated thermometers combine the most advanced mechanical instrument technology with the unique Weiss gas thermometer patented coil. The coil is produced by edge welding two strips of iso-elastic material and forming it into an extremely low volume, high strength, wall-to-wall C tube.The result is a system with low ambient error and extreme over-temperature capability and can provide narrow and wide ranges with the same small bulb.	SPECIFICATIONS ACCURACY ±1% of range span. AMBIENT ERROR 1/4% of span per 25°F change in ambient temperature at mid-scale. OVERRANGE - minimum 50% of span above top of range or 1300°F whichever is lower. Specific over-temperature capability is range dependant, so consult the factory for application beyond the above conditions. DIAL - white coated aluminum with black markings. POINTER - slotted adjustable type permits "zero set " calibration. THERMAL SYSTEMS - standard with stai nless steel spring armor, (stainless steel spiral interlock is optional) spiral interlock must be furnished on systems above 40ft.
