â¢ If using hot water to sanitize, use a calibrated thermometer to measure the water temperature. Refer to Using and Calibrating Thermometers SOPs. HACCP-Based SOPs 3 Cleaning and Sanitizing Food Contact Surfaces, continued (Sample SOP) MONITORING, continued: 3. Ensure that food contact surfaces reach a surface temperature of 160 o F or above if using hot water to sanitize. MONITORING: Foodservice employees will: 1. During all hours of operation, visually and physically inspect food contact surfaces of equipment and utensils to ensure that the surfaces are clean.
There are various principles by which different thermometers operate. They include the thermal expansion of solids or liquids with temperature, or the change in pressure of a gas on heating or cooling.Radiation-type thermometers measure the infrared energy emitted by an object, allowing measurement of temperature without contact.Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and scientific research.he precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 Â°C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 Â°C.
