Guide · CalibrationMeasurement uncertainty in medical laboratory temperature monitoringEvery temperature reading carries measurement uncertainty, and ISO 15189 expects a laboratory to take it into account when it decides whether a fridge, freezer or incubator is in or out of limits. You do that with a documented decision rule, usually guard banding or shared acceptance, applied consistently to your calibration results and alarm limits.2 August 2025 · 6 min read
Guide · Cold chainEnd-to-end cold chain monitoring, depot to deliveryEnd-to-end monitoring puts the store, the loading bay, the vehicle and the handover on one platform, so an excursion can be traced to where and why it happened. Separate systems for each stage leave gaps at exactly the points where most problems start: the handovers.16 July 2025 · 5 min read
Guide · CalibrationISO 17025-accredited calibration: why it mattersISO/IEC 17025 accreditation means an independent body, in the UK UKAS, has assessed a laboratory as competent to make specific measurements, so its calibration certificates carry traceability an inspector or auditor can rely on. For monitoring, it is the simplest way to show that the readings behind your records are right.13 July 2025 · 6 min read
Guide · How monitoring worksChoosing monitoring hardware for sites and fleetsPick hardware by what you are measuring, where it sits and what your inspector or auditor needs to see: LoRaWAN sensors and gateways for fixed sites, cellular trackers with Bluetooth sensors for vehicles and moving assets. This guide sets out the questions to ask and which device fits each job.6 June 2025 · 5 min read
Guide · Inspections and recordsEnvironmental monitoring in healthcare facilitiesHealthcare environmental monitoring means a continuous, traceable record of temperature (and where needed humidity) for every fridge, freezer, room and store that holds medicines, blood, samples or tissue, with alarms that reach a person and a recorded response. That record is what the CQC, MHRA, HTA and UKAS assessors look for, each in their own remit.1 June 2025 · 5 min read
Guide · Cold chainCold chain management for food logistics: a practical guideGood cold chain management means every stage from supplier to shelf is temperature-controlled, monitored and recorded, with no unmonitored handovers. In practice that takes five things: live monitoring in vehicles and stores, door visibility, calibrated sensors, one platform for storage and transport, and alarms that escalate to a person.18 May 2025 · 6 min read
Guide · Cold chainRolling out telematics in a logistics fleetTelematics puts a tracker in each vehicle that reports location, vehicle data and load temperature in real time, so you can act on a problem during the journey and prove the load stayed in range afterwards. It pays back when it is rolled out with clear goals, the right device for each vehicle class, a pilot, and someone who owns it.14 May 2025 · 5 min read
Guide · Cold chainUsing monitoring data to make better cold chain decisionsData-driven decisions in the cold chain means using your temperature, door and route records to find where and why problems happen, then fixing the cause rather than the symptom. The same data that proves compliance to an inspector can show which store, vehicle or shift needs attention.1 April 2025 · 4 min read
