What is an industrial temperature data logger?
An industrial temperature data logger records temperature readings continuously over time and stores every reading with a cryptographically verified timestamp.
The AIOTHUB logger adds what cold chain managers, lab technicians, and process engineers need on top: real-time alerts the moment temperatures leave safe bounds, local SD buffering that keeps logging through power cuts or network dropouts, and Modbus/MQTT for immediate SCADA and cloud integration.
It is the most dependable, low-cost way to ensure cold room integrity, prevent thermal batch spoilage, and pass strict FDA 21 CFR Part 11 or GxP audits.
Immediate Thermal Anomaly Detection, Complete Process Safety
From vaccine cold rooms to high-temperature furnace validation, the Temperature Data Logger keeps your records complete and your team notified.
Audit-ready compliance data
Tamper-evident, time-stamped records built for FDA 21 CFR Part 11, GxP, HACCP, and ISO 22000 quality standards.
Real-time alerts, zero downtime
Instant SMS, email, and WhatsApp notifications when temperatures spike, freeze, or cross your configured threshold limits.
Never lose a reading
On-board flash and expandable SD buffer continuously log temperature data through power disruptions or network dropouts.
Works with what you already run
Modbus RTU/TCP, MQTT, and OPC-UA drop straight into your PLCs, SCADA systems, and industrial cloud dashboards.

How to Choose the Right Temperature Data Logger
Six factors separate a logger that safely protects your thermal processes from one that fails during audit reviews.
Sensor type selection
Choose RTD Pt100 for high precision (±0.1°C in cold chain) or Thermocouples (J/K/T) for broad high-temperature furnace ranges.
Measurement resolution
Ensure 0.01°C resolution and low annual drift so your records maintain precision without frequent recalibration cycles.
Real-time cloud & alerting
Select units with Wi-Fi, 4G, or Ethernet to push excursion alerts instantly via SMS, WhatsApp, and email.
Memory & battery backup
Confirm internal SD buffering and rechargeable lithium backup so power outages cause zero gaps in your thermal records.
Regulatory compliance
Choose systems supporting FDA 21 CFR Part 11, GxP, and NABL traceability with automated tamper-proof PDF generation.

Temperature Data Logger FAQs
The questions engineers, cold chain managers, and purchase teams ask us most before ordering.
A temperature data logger automatically measures and records temperature over time. It gives you a time-stamped history of temperature changes, helping you verify cold chain stability, prevent product spoilage, and maintain regulatory compliance.
A thermometer only shows you a live reading. The AIOTHUB Temperature Data Logger records and stores every reading digitally with a timestamp, sends instant alerts when temperatures exceed safe limits, and maintains complete historical logs for inspections and audits.
The logger supports industrial RTD sensors (Pt100, Pt1000 in 2, 3, or 4-wire configs), Thermocouples (Types J, K, T, E, N, R, S), NTC thermistors, and digital IC temperature probes.
Depending on the connected sensor, the logger can record cryogenic freezer temperatures (−200°C) up to high industrial furnace temperatures (+1200°C).
The logger continues recording seamlessly to an industrial SD card. An internal rechargeable lithium battery provides 48 to 120 hours of backup, automatically synchronizing data to the cloud when power and connectivity return.
You can set upper and lower temperature limits. When temperatures drift out of safe range, instant notifications are broadcast via SMS, email, WhatsApp, and the onboard audio buzzer.
Yes. Every record is protected with AES-256 encryption and cryptographic SHA256 checksums that detect any unauthorized changes, ensuring the logs hold up as trustworthy evidence during audits.
Yes. Combined with the AIOTHUB cloud platform, it provides tamper-evident time-stamped electronic records, user access control, and automated compliance summaries meeting USFDA 21 CFR Part 11, HACCP, and ISO 22000.
Yes. Every unit can be supplied with an NABL-traceable 2-point and 3-point calibration certificate across your desired operating range.
Yes. It supports Modbus RTU (RS485), Modbus TCP, MQTT, and OPC-UA, allowing direct integration into existing PLC, SCADA, and building automation systems.
Yes. The external probes operate down to −80°C and −200°C, while the IP65 enclosure withstands frost, condensation, and cold storage room environments.
The AIOTHUB single-channel Temperature Data Logger starts from ₹12,000 for standard RTD/Thermocouple models. Multi-channel configurations are quoted based on channel count and probe specifications.
