Temperature Monitoring Services

Biomedical Engineering and Equipment Service Co. Inc. (BEESCO) offers a simple cost effective system for continuous temperature monitoring of EMS pharmaceuticals. The system employs Thermochron temperature recording I-buttons. Each Thermochron I-Button stores 1024 date and time stamped temperature readings. Data is retrieved through a standard personal computer serial connection. The data can be imported directly into Excel or similar software for analysis. The Thermochron I-Button can be programmed to record temperatures at intervals from 1 minute to 255 minutes. A sample interval of 20 minutes provides 28 days of temperature monitoring. A one hour sample interval provides 90 days of monitoring. Thermochron I-Buttons s may be reprogrammed for other missions and reused over and over. They have a typical life of five years

Customers may purchase Thermochron I-Buttons; software and the I-Button reader for use with there own computer system or BEESCO can provide a temperature monitoring service.

With our temperature monitoring service, the customer is mailed a supply of Thermochron I-Buttons preprogrammed for a sample rate specified by the customer. When the Thermochron I-Button has filled with temperature data the customer will mail them back to BEESCO via a supplied prepaid mailer. The data will be retrieved and then emailed back to the customer. Replacement Thermochron I-Buttons will then be sent to the customer for the next cycle of temperature monitoring.

Below is an example of data extracted from a Thermochron I-Button
