Pressure Models: Models 126-164, S164B, 610-614:-40 to 160°F (-40 to 71°C);Models 22-28; 16008, 16009: 0 to 160°F (-18 to 71°C)
Temperature Models: -40 to 160°F (-40 to 71°C). Set point typically shifts less than 1% of range for a 50°F (28°C) ambient temperature change.
SHOCK: Set point repeats after 15 G, 10 millisecond duration
VIBRATION: Set point repeats after 2.5 G, 5-500 CPS
