This is a pre-owned Cardinal Health T2960-5 Traceable Digital Thermometer w/ Hi/Low Memory & Alarm. This was removed from a working environment where it was very well cared for. It shows minor signs of use, if any.
This temperature monitor has a probe inside a small vial of liquid so its readings do not “jump” due to transient temperature changes (such as when a door is briefly opened). The device keeps track of maximum and minimum temperatures observed (there is a reset button for this feature). The device can also be programmed to alarm when temperature exceeds or falls below a chosen range.
