WIKA TI.31 bimetal thermometers offer the same features as the TI.30, with a fixed lower mount (bottom) connection. The hermetically-sealed case offers protection from weather and dust, and is guaranteed against fogging up. The TI.31 has a 7-year guarantee. Ranges: -100 degree F to 1000 degree F (and equivalent Celsius). Working range - steady: full scale value and short time: 110 percent of full scale value. Over range: temporary over or under range tolerance of 50 percent of scale up to 500 degree F. (260 degreeC). For ranges above 500 degree F, maximum over range is 800 degree F, continous. 1000 degree F intermittent. Connection: material 304 stainless steel, lower mount (CBM), 1/2" NPT. Measuring element: bi-metal helix. Pointer: black aluminum. Stem: 304 stainless steel material, stem measures 1/4" diameter by 4" length. TIG welded at tip and case connection. Case: 304 stainless steel Material, hermetically sealed per ASME B40.3 standard Ingress protection IP 65 external reset slotted hex head on back of case. Dial: anti-parallax, heavy gauge aluminum with white matte finish. Dampening: inert gel to minimize pointer oscillation. Standard scales: single: fahrenheit or celsius, dual: fahrenheit (outer) and celsius (inner). Window gasket: neoprene silicone (-100 degree F and over 550 degree F). Window: flat instrument fully gasketed glass. Movement: viscous inert gel to enhance pointer operation. Hermetic Seal: Per ASME B40.3, IP65, NEMA 4X.
