The temperature-buffering sensor sealed in the 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 ● Utilizes a temperature buffer-type sensor with propylene glycol solution, allowing measurements that closely approximate the temperature of liquid measurement targets. Additionally, it prevents false alarms caused by rapid temperature changes due to the opening and closing of refrigerator doors. ● Employs 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 sound alarm ● Enables 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 and lower limits, with notifications via warning sound and red LED flashing 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 employs a temperature-buffered sensor method that immerses a sensor probe in a bottle-sealed propylene glycol, allowing it to measure temperature changes of liquid vaccines and liquid clinical trial reagents without being affected by rapid 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 liquid clinical trial reagents and vaccines stored in refrigerators and freezers. *GRAS: Generally Recognized As Safe, a designation by the FDA for substances that are 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.
