TFA LT-102 30.1034 Digital Probe Thermometer with Alarm

Reliable Temperature Monitoring with Instant HI/LO Alerts

The TFA LT-102 digital probe thermometer is designed for professional temperature monitoring in refrigerators, freezers, liquids, food processing, laboratories and industrial environments. Its waterproof external sensor is connected by a generous 3 metre cable, allowing the probe to remain inside the monitored area while the display is positioned conveniently outside.

Adjustable upper and lower temperature limits provide both visual and audible warnings when readings move outside the required range. Combined with HACCP and EN 13485 compliance, this makes the LT-102 particularly suitable for professional food temperature control and refrigerated storage monitoring.

3 Metre Waterproof Temperature Probe

The waterproof immersion probe is connected to the display unit by an approximately 300cm cable. This makes it easy to monitor temperatures inside refrigerators and freezers while keeping the display accessible outside, or to measure the temperature of suitable liquids without immersing the main instrument.

Visual and Audible HI/LO Temperature Alarms

Set upper and lower temperature limits according to your application. If the measured temperature moves outside these limits, the thermometer provides both visual and audible alerts, helping users identify temperature deviations quickly.

Ideal for Refrigerators and Freezers

The remote cable probe makes the LT-102 particularly practical as a fridge and freezer thermometer. The sensor can remain inside the refrigerated area while the display is positioned externally, allowing temperatures to be checked without unnecessary door opening.

HACCP and EN 13485 Compliant

The LT-102 is compliant with HACCP requirements and EN 13485, making it suitable for professional temperature measurements within food industry self-monitoring procedures. It is an excellent choice for catering, food preparation, refrigerated storage and other applications where dependable temperature control is important.

Monitor Liquids with the Waterproof Probe

In addition to refrigerated storage, the waterproof probe can be used for temperature measurement in suitable liquids, extending the thermometer’s use to food processing, laboratories, industry and other professional applications.

MAX, MIN and HOLD Functions

The thermometer records maximum and minimum measured temperatures, helping users review temperature extremes. A data hold function can also retain the current measurement on the display when required.

Flexible Magnetic or Freestanding Display

The display unit features an integrated magnet for attachment to suitable metal surfaces and can also be positioned freestanding, providing flexible placement around refrigerators, freezers, workbenches and laboratory equipment.
