Primex provides two types of temperature probes - Cryo and Standard. Standard probes are available as a standalone probe or with a thermobuffer*.
Each type of probe has a unique catalog part number and quality control number. You can identify the type of probe by its quality control number (Q-XXXXX-X) that is printed on the label attached to its cable.
Using its quality control number, refer to the chart below to identify the probe type. When you are needing a replacement probe, be sure to provide the corresponding catalog part number.

*Why a thermobuffer?
The use of a thermobuffer can eliminate temperature spikes due to frequent refrigerator or freezer door opening and decrease false alarms.
A Thermobuffer is used to simulate the temperature of refrigerated assets rather than the air temperature of a refrigeration unit. The bottle, either filled with food grade glycol or solid wax, allows for slower reaction to abrupt temperature changes, yet still maintain long-term accuracy if the temperature change remains permanent.
