Elitech LogEt 1TH Temperature and Humidity Data Logger

A) Product overview

The Elitech LogEt-1 Series is a single-use cold-chain data logger family for shipment and storage monitoring. It records temperature (LogEt-1) and temperature and humidity (LogEt-1 TH) with high-accuracy sensors, shows status on an LCD, and generates an auto-encrypted, password-protected PDF report via a built-in USB plug-and-play interface. With up to 16,000 readings, configurable logging intervals and alarms, and a light sensor for door-opening/handling violation detection, it is designed for pharmaceutical cold chains, vaccine logistics, food storage, and temperature-sensitive transport.

Key differentiators

• Single-use temperature (LogEt-1) or temperature and humidity (LogEt-1 TH) monitoring

• Auto-encrypted PDF report with password protection (USB plug-and-play)

• LCD display for real-time visibility and status checks

• Light sensor to detect door-opening/unauthorized exposure events

• 16,000-reading memory, up to 120-day recording duration

• Protection: IP67 (LogEt-1), IP65 (LogEt-1 TH)

• Compatible configuration tools: ElitechLog software and Elitech iCold cloud

B) Working principle

1. Measurement: The device uses an internal high-precision sensor to measure temperature continuously; the TH variant also measures humidity (0–100% RH).

2. Sampling and storage: Readings are captured at a configured logging interval (12 minutes default, adjustable) and stored in internal memory (up to 16,000 readings).

3. Alarm evaluation: Pre-set or customised alarm limits evaluate whether the product has exceeded temperature/humidity thresholds during transit or storage.

4. Event detection: A light sensor detects exposure events that typically indicate door opening, package opening, or handling violations, and flags them in the trip record.

5. Display and status: The LCD provides at-a-glance visibility of current readings and device status for quick field checks.

6. Report generation: After the trip, plug the logger directly into a PC USB port; it automatically generates an encrypted PDF report with password protection for easy sharing and compliance records.

7. Configuration (before use): Logging interval, start/stop method, and alarm thresholds can be configured using ElitechLog software or Elitech iCold cloud (as applicable).

C) Why it is used

The LogEt-1 Series is used to create an auditable, easy-to-share record of cold-chain conditions for temperature-sensitive goods. It helps reduce product loss, prevent disputes with transporters, and meet compliance requirements by providing clear documentation of temperature (and humidity, on TH) from dispatch to delivery.

Common reasons companies choose LogEt-1 / LogEt-1 TH

• Cold-chain compliance documentation with secure, encrypted PDF reports

• Shipment validation for pharma, vaccines, and biological samples

• Food logistics and cold storage monitoring for perishables

• Quick in-field verification via LCD display

• Incident detection through light sensor (door-opening/handling exposure)

• Disposable single-use format for one trip without retrieval logistics

D) Suitable buyers

Pharmaceutical and healthcare cold chain

• Pharma manufacturers, vaccine distributors, cold-chain 3PLs, CFAs, hospitals, blood banks, diagnostic labs, clinical trial logistics providers

Food and perishables logistics

• Dairy and frozen food companies, seafood/meat exporters, fresh produce distributors, cold storage operators, reefer truck operators

Life sciences and research supply chain

• Biotech companies, laboratories, reagent suppliers, research institutes shipping temperature- and humidity-sensitive materials

Quality, compliance, and operations teams

• QA/QC managers, compliance officers, warehouse managers, logistics heads, procurement teams standardizing trip validation and documentation

Thermal packaging and export channel partners

• Cooler-box/thermal packaging vendors, freight forwarders, exporters shipping temperature-sensitive cargo by road/air/sea

FAQ

1) What is the Elitech LogEt-1 Series used for?
It is used for cold-chain monitoring of temperature-sensitive shipments and storage in pharma, vaccines, life sciences, and food logistics, with documentation via PDF reports.

2) What is the difference between LogEt-1 and LogEt-1 TH?
LogEt-1 records temperature only. LogEt-1 TH records both temperature and humidity (0–100% RH).

3) Does it require software to download the report?
No. The logger generates an encrypted, password-protected PDF report automatically when plugged into a PC via USB.

4) How many readings can it store?
Up to 16,000 readings (temperature, or temperature + humidity, depending on the model and configuration).

5) Can I change the logging interval and alarm thresholds?
Yes. Logging interval (12 minutes default) and alarm limits can be configured using ElitechLog software or Elitech iCold cloud (as applicable).

6) How long can it record data?
Up to 120 days depending on the logging interval and configuration.

7) Is the device waterproof?
Yes. LogEt-1 is rated IP67. LogEt-1 TH is rated IP65 (splash/dust protection).

8) What is the purpose of the light sensor?
It helps detect door-opening or unauthorised exposure events during transport, supporting traceability and handling compliance.

9) Does it show readings on the device?
Yes. The LCD display provides real-time visibility of readings and status for quick checks.
