In Indiana, addictions counselors may be licensed at the bachelor's or master's level.
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.
Resistance thermometers measure temperature of an. object based on changes in electrical resistance of the. sensing element. Two types of resistance thermometers are. commonly used: thermistors and resistance temperature. devices (RTD). A thermistor uses a semiconductor as the sensing. element. The electrical resistance of the semiconductor, made mostly from metallic oxides (e.g., NiO), decreases. sharply as the temperature increases.
