The temperature buffer sensor, sealed in a bottle with propylene glycol, is unaffected by sudden changes in internal temperature caused by opening and closing the refrigerator door, ensuring the stability of vaccines and investigational drugs.
■Features ● High/low temperature alarm setting function ● By adopting a temperature-buffered sensor using propylene glycol solution, measurements can closely approximate the temperature of liquid measurement subjects. Additionally, it prevents alarm malfunctions caused by rapid temperature changes due to the opening and closing of refrigerator doors. ● Uses gold-plated stereo jack connectors to reduce reading errors ● Memory function to record the highest/lowest measured temperatures ● Large display screen ● Comes with a fixing magnet and a folding stand ● Retains previous settings even during battery replacement ● Function to delay the buzzer alarm ● Achieves continuous temperature monitoring for over one year ● Ideal for temperature monitoring of liquid vaccines and investigational reagents stored in refrigerators and freezers ● Temperature calibration certificate compliant with ISO/IEC 17025:2017, with one point calibration between -30°C and 30°C ● Alarm delay function ● Memory function for maximum/minimum values ● Allows arbitrary setting of upper/lower limits, notifying with a warning sound and red LED blinking when the set values are exceeded ● Large display ● Battery level indicator ● Maintains settings during battery replacement*6 ● Includes a mounting magnet on the back of the product

basic information
■Usage Examples Hospitals, laboratories, pharmacies, refrigerators, freezers The M994EL-2334912D adopts a temperature-buffering sensor method that immerses a sensor probe in propylene glycol sealed in a bottle, allowing it to measure temperature changes of liquid vaccines and liquid clinical trial reagents without being affected by sudden temperature fluctuations caused by frequent opening and closing of refrigerator and freezer doors. The propylene glycol used for temperature buffering is certified as a GRAS* substance by the FDA (U.S. Food and Drug Administration), ensuring safety even in the event of a liquid leak. It provides temperature measurements that approximate the temperature behavior of clinical trial reagents and vaccines stored in liquid form in refrigerators and freezers. *GRAS: Generally Recognized As Safe, a designation by the FDA for substances considered safe. The M994EL-2334912D digital thermometer with maximum/minimum alarm features a maximum/minimum memory function, a large and easy-to-read display, and high/low temperature alarm settings. This product is ideal for monitoring temperatures inside freezers, refrigerators, and refrigerated display cases.
