Tab Mount Surface Thermometer

Two types of tabs are available for these thermometers. Tab 1 is for on-surface mounting and Tab 2 for in-surface mounting. The drawings show both methods of mounting. For in-surface mounting, a hole, -1/8", in diameter by 1/4" deep is machined in the part to be measured. Holes also need to be drilled for mounting screws. The tabs are provided with holes for the screws. Ancillary hands are available for both Tab 1 and Tab 2 Models and are designated by adding an "L" to the model number (eg. 312F T1L would be a 0°F to 250°F thermometer with Tab 1 mounting and an ancillary hand)
