21 CFR Part 11 Compliant Data Loggers & Monitoring

Part 11 is a US regulation, but its reach in India is wide. Any site that makes, tests, stores or ships product for the US market and keeps GMP records electronically falls under it: formulation and API plants filing with US-FDA, contract research organisations generating study data, CDMOs manufacturing for US sponsors, and the warehouses and 3PLs that hold their stock. Temperature and humidity records are GMP records, so the monitoring system in a stability chamber, cold room or finished-goods warehouse is in scope as soon as those records are used to release a batch or defend it.

Domestic-only manufacturers now meet the same questions from export customers, from the auditors of multinational partners and, under Revised Schedule M, from Indian inspectors who expect computerised systems to be validated and their data protected.

21 CFR Part 11 sets the conditions under which the US-FDA accepts electronic records (Subpart B) and electronic signatures (Subpart C): system validation, secure audit trails, limited access, operational checks and signature controls. FDA guidance allows a risk-based approach to some provisions, but audit trails and access control still feature heavily in inspection findings.

EU GMP Annex 11 covers computerised systems for the European market. It asks for many of the same record controls but puts more weight on the life cycle: supplier assessment, risk management, periodic review and business continuity. Revised Schedule M, India's GMP rule, expects validated computerised systems and reliable data without prescribing Part 11 mechanics. A monitoring system built for Part 11 usually covers the record controls of all three; the life-cycle items live in your SOPs.

Inspectors rarely ask whether a system is Part 11 compliant. They ask to see evidence. Part 11 requires audit trails that are computer-generated, time-stamped, record the operator, never obscure earlier entries and are kept as long as the record itself. In a monitoring review, expect requests like these:

The checklist above follows the order most validation teams work in: identity and access first, then the integrity of the data, then signatures, then evidence and retention. For each row, ask the vendor to demonstrate the control live rather than tick a questionnaire, and record the result in your supplier assessment.

Keep the split of responsibility clear. The vendor supplies a system capable of compliance and documents that support validation. You, the regulated user, own the user requirement specification, the risk assessment, performance qualification in your own facility, the SOPs for access, data review and backup, and periodic review. No data logger is compliant on its own out of the box; a validated system operated under approved SOPs is.

Ideabytes IoT has built data loggers since 2009. Its networked loggers, on Wi-Fi, 4G M2M with a built-in SIM, or Ethernet, send readings to a cloud platform with web and mobile apps for iOS and Android. Listed software features include 21 CFR Part 11 compliant PDF reports, scheduled and on-demand reports, MKT values, audit trail, alarm logs, trend graphs, live alerts with app push notifications, optional SMS and CAPA records. Some software features are delivered in different plans, so confirm the plan at quotation.

On the hardware side, single-channel loggers store 90 days of readings at a 15-minute interval and the 8-channel PT100 units hold 40,000 records if the network drops, with internal Li-ion batteries to ride through power cuts. The USB logger UT70 produces an encrypted PDF report when plugged in, with no extra software. 44 of the 46 products in our catalogue list FDA 21 CFR Part 11, CE, FCC and IC in their compliance data.

Electronic signatures are the row buyers most often skip. If QA signs off monthly temperature reports or excursion investigations electronically, each signature must show the printed name, date, time and meaning of the signature, be linked to the record so it cannot be copied to another, and belong to one unique user. If your process prints reports and signs them by hand, the signature controls apply less directly, but the electronic record behind the printout must still be protected and retained. Tell us which workflow you use and we will explain how the platform supports it.
