• Five installation options — probe with mounting flange or bulkhead fitting, plastic, galvanized steel, or NEMA-4 / IP65 steel enclosure offer the industry’s most extensive range to satisfy all HVAC, appliance and industrial applications.
• 304 SS thin wall probe with a cold rolled hermetically sealed end forms a monolithic encapsulation cavity for the sensor and is immune to failures caused by high humidity, contamination, thermal shock and vibration.
• The flat probe end provides a large thermally sensitive area and the sensor is in direct thermal contact to this surface. As a result, extremely fast response is achieved to changes in temperature. 
• Probe is attached to the enclosure or the flange using a patented process to provide a rugged, reliable and low profile attachment for ease of installation.
•  More than 16 types of interchangeable NTC thermistors, precision platinum, nickel or balco RTDs are available for universal compatibility.
