There is no better guarantee of quality bimetallic dial thermometers than the name Tel-Tru Manufacturing Company. The models A52, R52 bimetallic thermometers are the entrylevel model among process thermometers. Hold the calibration nut securely with a wrench or other tool and rotate the head of the thermometer until it reads 32°F (0°C). Bimetal thermometers are ideal for local, eye-level temperature readings in most process applications. Many food thermometers have a calibration nut under the dial that can be adjusted. There are also thermometer calibration services who will do this for a price. Red and blue pointers to indicate highest and lowest temperatures reached since reset. Please contact us if you're looking for something in particular. The target markets of this thermometer are air-conditioning and machine building. The procedure varies according to instruments scale. All available with a 3-5 day lead time! Bimetallic stemmed thermometers are calibrated using the ice-point method. One method uses ice water, the other uses boiling water.

In some critical applications calibration against a certified reference thermometer is required. The calibration of the industrial thermometer cannot be done. ... • Bimetallic, dial-faced stem thermometers are produced with a dimple mark located on the stem of the thermometer. reference thermometer used for calibration. These thermometers are classified into two types like the spiral strip and helical type. The target markets of this thermometer are air-conditioning and machine building. The bi-metal coil is enclosed in a stainless steel immersion tube and exposed to the temperature of the measured medium. Models A52, R52 are manufactured in accordance with EN 13190 and already offer a stainless steel case and accuracy class 1 for nominal sizes > 60 mm. Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it. The models A52, R52 bimetallic thermometers are the entrylevel model among process thermometers. Many food thermometers have a calibration nut under the dial that can be adjusted. 2. Periodically, all thermometers should be calibrated or adjusted so that they measure temperatures accurately. 2. After fingers were pointed at equipment manufacturers and at yeast suppliers the end result was the gauge thermometer they were using in their Mashtun was 5 degrees off. We recently heard a story where a commercial brewery was not obtaining the final gravities they were expecting. Models A52, R52 are manufactured in accordance with EN 13190 and already offer a stainless steel case and accuracy class 1 for nominal sizes > 60 mm. Instrument calibration : carried out through thermostatic baths controlled by microprocessor based moni- toring units. A variety of options are available for your specific process needs. The designing of this thermometer can be done by wrapping the bimetallic strip into this thermometer. Dial Thermometers by WIKA - market leader since 1946 Our dial thermometers work on the bimetal, expansion or gas actuation principle. thermometer calibration log. Remove the thermometer from its case and slide the stem through the hole in the wrench pocket (no additional tools required) until the adjusting nut below the dial head snaps securely in place. For an inaccurate, bimetallic, dial-faced thermometer, adjust the temperature by turning the dial while securing the calibration nut (located just under or below the dial) with pliers or a wrench. bimetallic thermometer scale thermometers Prior art date 1946-06-24 ... A series of errors due to vibration and minor shocks will usually tend to compensate for each other and successive calibration adjustments of the thermometer will shift the pointer 12 back and forth in the neighborhood of the zero calibration line l8. Ice Water To use the ice water method, fill a large glass with finely crushed ice. A variety of stem lengths mean they can be fit into projects with limited space availability. Calibrating a Thermometer There are two ways to check the accuracy of a food thermometer: using ice water or using boiling water. Toll Free: 800.544.2843 Models A52, R52 are manufactured in accordance with EN 13190 and already offer a stainless steel case and accuracy class 1 for nominal sizes > 60 mm. Calibration of Liquid-in-Glass Thermometers: The usual method of calibrating these instruments is to determine their ice-points. Ice Water To use the ice water method, fill a large glass with finely crushed ice. Our local reading industrial thermometers operate on the bi-metal coil principle.
