HTC Easy Log Temperature & Humidity Data Logger

A. Product Overview

The HTC Easy Log is a compact, high-accuracy temperature and humidity data logger designed for continuous environmental monitoring. It supports a wide measurement range, displays live status on an LCD screen, and stores up to 32,700 total readings (temperature and humidity combined). With a selectable logging interval from 1 second to 24 hours, USB data download, and PC software for analysis, it is suitable for long-duration monitoring in cold chain, storage, laboratories, pharma facilities, and HVAC environments. The unit is battery-powered (3.6V ER 14250) and built for portable, user-friendly operation with clear alarm/record indicators and a rugged form factor.

Key highlights:

• Memory: up to 32,700 readings

• Interval: 1 sec to 24 hrs

• Display: LCD with real-time logging information

• Alerts: high/low alarm indication, LED status indicators

• Interface: USB with PC software (graphical/text viewing)

• Battery life: over 3 years (at 22°C, typical use)

B. Working Principle

The HTC Easy Log works by measuring temperature and relative humidity at fixed time intervals and saving each measurement as a timestamped data record in its internal memory.

1. Sensing: Internal sensors detect temperature and relative humidity.

2. Sampling: The logger samples readings based on the user-selected interval (1 sec to 24 hrs).

3. Storing: Each reading is stored until memory is full (up to 32,700 readings).

4. Monitoring: The LCD displays real-time logging status and basic information during operation.

5. Alarming: When readings cross configured high/low limits, the device provides alarm indication (LED status).

6. Data Retrieval: Logged data is transferred through the USB interface to a computer.

7. Analysis: PC software is used to view and analyze results in graphical or text format for reporting and review.

C. Why It Is Used

The HTC Easy Log is used to ensure reliable documentation and control of temperature and humidity conditions where environmental stability matters for product quality, safety, and process reliability.

Typical reasons to use it:

• Cold chain monitoring: Track storage and transport conditions for temperature-sensitive materials.

• Warehouses and storage rooms: Verify conditions over long periods to prevent spoilage, degradation, or moisture issues.

• Pharma and healthcare facilities: Maintain environmental logs for sensitive items and controlled areas.

• Laboratories and R&D centers: Document test conditions, stability environments, and storage parameters.

• HVAC monitoring: Validate and troubleshoot room and system performance using logged temperature/RH trends.

D. Suitable Buyers

This product is suitable for:

• Pharmaceutical manufacturers and distributors (storage rooms, dispatch, temperature/RH verification)

• Cold chain logistics providers (monitoring during storage and movement)

• Hospitals, clinics, and healthcare facilities (controlled storage areas)

• Warehouse operators and 3PL companies (environment monitoring and audits)

• Laboratories and R&D teams (test condition logging and documentation)

• HVAC engineers and facility managers (performance monitoring, troubleshooting, and validation)

• Quality assurance and compliance teams who need consistent, recorded environmental data
