HACCP Temperature/RH Thermometer Wall Thermometers
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...
Learning Lessons from Hurricanes
The lessons continually learned from hurricanes are still unfolding, but we have one that will help when another natural disaster strikes. As we learned many systems that businesses use to monitor their important environments such as refrigerators and freezers in restaurants, cafeterias, and medical facilities lost power. When this happened, several customers told us the systems they use to track the temperatures also failed since they relied on electrical power as well. A simple precaution is a min/max thermometer that does not rely on power. At Sper Scientific, we have two models that are ideal for this use: 736680 and 736690. These thermometers...
Sper Scientific Min-Max Thermometers Offer Accurate and Affordable Temperature Monitoring
Temperature/RH Wall Thermometers
Used for greenhouse temperature monitoring, the Sper Scientific Min-Max Thermometer is available in two models. Model 736680 includes a magnetic float reset and features dual scales of -50/50°C & -60/120°F. Model 736690 features a push-button reset and dual scales of -50/50°C & -60/120°F. Sper Scientific Min-Max Thermometers allow easy spot checking of temperature in a greenhouse or other temperature-sensitive environment. Sper Scientific Min-Max Thermometers are available at SperDirect.com.
