A probe per unit, independent of the equipment.
Each unit gets a sealed probe placed inside it, wired back to a TempGuard device mounted outside, reporting over its own SIM. It does not connect to the equipment, replace a built-in display, or need anything from the instrument's own controller.
That independence is the point. A unit's own thermostat is a control device: it reports what it is trying to do. A separate probe reports what the space is actually at, which is the reading you want when the two disagree.
Every unit carries its own range and its own recipients, so a -80 °C freezer, a 2–8 °C reagent fridge and a 37 °C incubator are three separate records with three different escalation paths.
Through the refrigerated, ambient and incubator bands the sensor reads to within ±0.5 °C. The operating range runs from -55 °C to +125 °C. For ultra-low freezers below -55 °C, or anywhere you need a tighter margin than the standard probe carries, tell us the range and the tolerance and we will scope the sensor for it.
Continuity, not spot checks.
The question a lab has to answer about stored material is not what the freezer reads today. It is whether the storage condition held for the whole time the material was in it.
- Continuous readings
- Every unit, around the clock, each reading timestamped by the server rather than by the device.
- All four channels
- A breach dispatches a phone call, WhatsApp, email and mobile push together. Out of hours, the call is the one that reaches somebody in time to move material.
- Escalation
- An alert nobody acknowledges within 60 minutes escalates, and the absence of a response is recorded alongside it.
- Excursions with duration and depth
- How far out, and for how long. That is what decides whether material is still fit to use, and it is the part a twice-daily log cannot reconstruct.
- Silence detected
- A device that stops reporting is flagged after 24 hours, so an unmonitored period is visible rather than blank.
- Nothing can be rewritten
- A stored reading cannot be edited or deleted by any account, including ours. The database refuses the write.
- Attribution
- Who acknowledged, who resolved, and when. Changes to thresholds, devices and user access are logged separately, showing the person, the field and both values.
- Export per unit or per window
- Readings, excursions and the change log as CSV, plus a summary as PDF, for any date range.
Where it goes in practice.
- Sample & specimen storage
- Material that is often irreplaceable, sometimes consented for a single study, and worth more than everything around it.
- Reagent refrigerators
- Two-to-eight units opened constantly through a working day, where a failed door seal is the usual cause.
- Incubators & controlled rooms
- Spaces held at a setpoint rather than kept cold, where drift in either direction matters.
- Stability & retention storage
- Long-horizon storage where the evidence has to cover months, and where nobody notices a slow drift without a trend.
- Diagnostic labs holding medicines
- Where a lab also stores pharmaceutical stock, the pharmaceutical storage rules apply to that stock as well as its own protocols.
- Multi-site groups
- Several labs under one quality system, on one dashboard, with users scoped to their own sites.
What your auditor is likely to ask for.
Laboratories are not governed by a single UAE temperature regulation the way food premises and pharmacies are. What you are held to comes from the accreditation your lab holds, the standards your methods are written against, and your own study protocols. Those differ between a diagnostic lab, a research group and a contract testing house.
What they tend to have in common is the shape of the evidence, and it is the same shape TempGuard produces:
- The storage condition, continuously
- Not a reading at a moment, but the whole period the material was held.
- Deviations, quantified
- Every excursion with its duration and depth, so an impact assessment has something to work from.
- The action taken
- Who was alerted, who responded, when, and what they recorded. Corrective action with a name against it.
- A record that cannot be adjusted
- Readings that no account can edit or delete after the fact, with configuration changes logged separately.
- Instrument status
- A calibration date and expiry per device, reported as valid, expiring or expired, so a lapsed unit surfaces before an assessor finds it.
Where a laboratory also stores pharmaceutical stock, that stock carries the expectations of pharmaceutical storage as well as the lab's own: the 2 °C to 8 °C cold chain band, conditions monitored and recorded rather than spot-checked, and records available on request.
Your requirements come from your accreditation body, your licensing authority and your own protocols, and only you know which those are.
This page describes what TempGuard records. It is not regulatory advice, and it is not a statement that using TempGuard makes you compliant or accredited. Your assessor and your own quality team decide that.
