The Oakton® Food TempTestr® II Infrared Thermometer is the easy way to determine safe food preparation or storage temperatures. Non-contact measurement eliminates the risk of cross-contamination. Temperature measurement is essential when ensuring proper food storage, cooking and serving environments, and is required by the FDA. Quick checks with a non-contact thermometer can remove the hazard of cross-contamination and reduces cycle time over a traditional penetration probe. This thermometer provides this safe, non-contact reading in under a second. Use the TempTestr ® to monitor HACCP danger zone temperature standards for food (40 to 140degF or 4 to 60degC), the critical range where harmful bacteria grows most rapidly. LED’s on the meter quickly indicate if the food temperature is within a green or red bacterial growth zone. A green LED light indicates food-safe hot and cold holding temperatures. Red LED light indicates that food is exposed to potentially danger. Includes one (1) 9 V battery and wrist strap.
