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...

At Sper Scientific, we certify two categories of instruments:  Newly purchased instruments are certified prior to shipment, which may extend your order ship day by up to 10 business days. Not all instruments can be certified, when certification is possible an ordering option will appear on the product page. Previously purchased instruments are returned annually to Sper Scientific for certification, and may take up to 10 business days to certify. Purpose of the Program:There is an increasing requirement by customers for documentation supporting manufacturer’s claims of accuracy on their scientific equipment. This is partially due to the increasing acceptance of quality...

   An anemometer is a device used for measuring wind speed. The term is derived from the Greek word anemos, meaning wind, and is used to describe any air speed measurement instrument used in meteorology or aerodynamics. The first known description of an anemometer was given by Leon Battista Alberti around 1450. The simplest form in common use is the cup anemometer, which catches the wind with rotating cups, usually four. Cup anemometers are still used for wind, power performance evaluations and site calibrations. An anemometer is also a common instrument used in HVAC. Specifically for indoor air quality and HVAC / R technicians measuring Heat / Ventilation...

  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.

The Sper Scientific Water Quality Meter Model 850081 uses interchangeable probes to read pH, mV, conductivity, TDS, DO, temperature and ORP, diminishing the need for multiple devices dedicated to testing limited parameters. The user can order probes for only the parameters currently required, and add additional probes in the future. Intelligent probes electronically retain calibration information. No recalibration is required when changing probes. The display simultaneously reads temperature in user selectable °C & °F, and all measurements are automatically temperature compensated. RS232 port enables communication with a computer. Also features auto power off, hold, min/max, fold-out easel back and a tripod...
