Food Safety HACCP Temperature/RH Thermometer

NEW HACCP Thermometer- Designed for food safety in compliance with HACCP principles

Sper Scientific is excited to announce the launch of the HACCP Thermometer- 800042. This thermometer is designed specifically for the food safety industry in compliance with HACCP principles. The thermometer offers a wide temperature range and high degree of accuracy. Hazard Analysis Critical Control Point (HACCP) is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. HACCP itself was conceived in the 1960s when the US National Aeronautics and Space Administration (NASA) asked...

Useful Temperature Information and Conversion Chart

Temperature is defined as the degree of hotness or coldness, as measured on a definite scale. Three temperature scales are in general use today: The Fahrenheit (°F) temperature scale is used in the United States and a few other English-speaking countries. The Celsius (°C) temperature scale is standard in virtually all countries that have adopted the metric system of measurement, and it is widely used in the sciences. The Kelvin (K) scale, an absolute temperature scale (obtained by shifting the Celsius scale by −273.15° so that absolute zero coincides with 0 K), is recognized as the international standard for scientific temperature...

About Infrared (IR) Thermometers: Distance to Spot Ratio

Infrared IR Temperature/RH Thermometer

About Infrared (IR) Thermometers: Distance to Spot Ratio

The actual area being measured is determined by the distance-to-spot ratio of the IR thermometer you are using, and this varies from model to model. As the distance from the object being measured increases, the spot size of the area being measured also increases.  For example, Sper Scientific’s IR Pen has a distance to spot ratio of 6:1 meaning that at 6" from the target it will measures the temperature of a 1" circle. At 2" it will measure a 12" diameter and so forth. See Sper's full line of Infrared Thermometers here.

Why Is Temperature Important?

Why Is Temperature Important?

   Temperature plays a crucial role in medical care (both humans and animals), food, beverages, and agriculture. Our overall health is often reliant upon temperature in many ways as well. Maintaining proper temperature levels in medical cold storage areas is critical.  Incorrect temperatures can compromise the medications or vaccines stored in medical refrigerators. High temperature and high humidity are the two most important factors in drug degradation. When exposed to these conditions, the medications can weaken. Moreover, you can face fines or penalties if your medical refrigerators are not performing properly. The CDC conducted a study that highlighted the improper storage and handling of vaccines. Unfortunately, 76 percent...
