Temperature Guard has been making quality products since 1977. We currently specialize in Food Service, Medical, and Industrial grade applications. We offer quality products from a family business.

Sensors for use with our products

Temperature sensor in vial filled with glycol


The BP2-G temperature sensor is perfect for monitoring product in refrigerators and freezers.

Temperature sensors in glycol are recommend by the CDC as well as the VFC program.

This sensor can be ordered with a NIST certificate.

BP2-G $50.00
BP2-G-NIST: $70.00

Lead time for NIST Cerificate is up to 10 days.

Spec Sheet for BP2-G

Temperature sensor in vial filled with glass beads


The temperature sensor in beads helps to prevent sudden temperature spikes when a door is opened.

The BP-V is perfect for applications where glycol is not required.

The vial with glass beads can be ordered seperately.

BP-V $40.00
BP-V-NIST $60.00
Lead time for NIST Cerificate is up to 10 days.

Vial with glass beads only $16.00

Spec Sheet for BP-V

Temperature Sensor Installation Kits

For a clean installation, any of our sensors can be ordered as a kit that includes a thin flexible cable that wraps smoothly around the edge of the fridge/freezer and does not interfere with its seal.

The kit includes:

  • One Temperature sensor in vial
  • One 25' of extension cable
  • One Flexible cable


BP2-G Flex Kit $85.00
BP2-G-NIST Flex Kit: $105.00

BP-V Flex Kit $75.00
BP-V-NIST Flex Kit $95.00

Installation Guide
