Laboratory Fridge Thermometer TFA LT-105 — ISO‑certified monitoring for cold storage

Protect your sensitive samples with the TFA LT‑105, a purpose‑built digital thermometer designed for laboratory refrigerators and freezers. Its ISO‑certified accuracy, HI/LO alarm and Max‑Min memory help you maintain traceable control over critical temperatures. A mineral glass bottle prefilled with Glysofor thermal buffer stabilises the probe response to avoid false alarms during door openings, while the compact display mounts easily outside the appliance for quick checks. Ready to use out of the box with an included battery and mounting accessories, the LT‑105 brings reliable, audit‑friendly temperature monitoring to any laboratory workflow.

Key Benefits and Applications

• ISO‑certified confidence — Supplied with an ISO certificate at key cold‑storage points for trustworthy documentation and simplified audits in regulated environments.
• Fewer false alarms — The included glass bottle with Glysofor creates a stable thermal mass that reflects stored product temperature, reducing nuisance alerts from brief door openings.
• Two readings at a glance — Monitor the storage temperature via the cable probe and check room temperature on the same device for complete situational awareness.
• Immediate threshold protection — HI/LO alarm lets you set custom limits so you are alerted as soon as temperatures drift beyond acceptable ranges.
• Track excursions with ease — Max‑Min memory displays the highest and lowest values reached, supporting investigations and routine temperature logs.
• Fast, clean installation — Magnetic mounting and adhesive pads position the display outside the fridge while the probe sits inside, keeping doors sealed and cables tidy.
