Cold storage temperature log
A per-shift temperature log for walk-in coolers, freezers and cold rooms: the display reading, an independent thermometer reading and a product temperature against your limits, a short condition check of door seals, ice build-up, drains and alarms, and a corrective action when a reading is out of range.

Before you use it
- A general log. It makes no claim about what any regulation requires: the temperature limits, the reading frequency and how long to keep the records come from your product specifications, your food safety or quality plan and the unit manufacturer, so enter those limits before the first reading.
- Record two temperatures, not one: the unit’s own display and an independent calibrated thermometer placed where the product sits. A display that reads fine while the product is warm is the failure this log is meant to catch.
- Run it per unit so each cooler, freezer or cold room has its own history. A reading outside the limit becomes a corrective action with an owner, and a repeat of the same unit becomes a work order on the unit, not another line in the log.

In Vardian, readings are checked against their limits as they are entered, and photos and signatures attach to the check itself.
From the sheet to the round
Build a template as a Vardian form, and each line becomes a checkpoint that knows its limit.
Animation: a paper checklist line, compressor discharge pressure with a blank for the reading in bar, becomes a Vardian checkpoint with a limit of 7.0 to 8.5 bar. Scanning the compressor's NFC tag verifies the checkpoint, a reading of 9.1 bar is flagged out of range, and a work order is created from it.

We'll set it up in Vardian with your checkpoints and limits during a demo.
