Elitech RC-4HC Digital Temperature and Humidity Data Logger

A) Product overview

Elitech RC-4HC is a digital temperature and humidity data logger designed for storage and transport monitoring. It measures temperature and RH using an internal sensor, and extends temperature measurement using an external probe for wider range applications. It features an LCD display, buzzer alarm, 16,000-record memory, IP64 protection, and Micro-USB data download. Using ElitechLog software on Windows or macOS, users can generate and export reports in PDF, Excel, or TXT formats for documentation and audits.

Key specs (quick):

• External temperature range: -40°C to 85°C

• Internal temperature range: -30°C to 60°C

• Temperature accuracy: ±0.5°C

• Humidity accuracy: ±3%RH (25°C, 20–80%RH)

• Memory: 16,000 groups

• Protection: IP64

• Interface: Micro USB

• Reports: PDF, Excel, TXT via ElitechLog (Windows, macOS)

B) Working principle

1. Measurement: The logger continuously measures temperature and humidity through its internal sensing element, while the external sensor measures temperature over a wider range where required.

2. Sampling and storage: At the selected logging interval, the device converts the sensor signals into digital readings and stores them as time-stamped records in internal memory (up to 16,000 groups).

3. Alarm monitoring: If readings cross preset high/low limits, the device triggers an on-screen indication and buzzer alarm, alerting users to potential excursions.

4. Data retrieval and reporting: When connected via Micro USB, ElitechLog software reads the stored data and allows users to export reports in PDF, Excel, or TXT for analysis and compliance documentation.

C) Why it is used

Elitech RC-4HC is used to maintain product quality, process stability, and compliance by proving that temperature and humidity stayed within required limits. It helps users:

• Detect temperature excursions during shipment, storage, or production holding

• Maintain cold chain compliance for pharma, vaccines, biologics, and temperature-sensitive materials

• Validate warehouse, cold room, and laboratory environmental conditions

• Generate audit-ready reports for QA, customers, and regulatory requirements

• Reduce spoilage, rejects, and disputes by providing traceable data logs

D) Suitable buyers

This model is best suited for buyers who need reliable, documented temperature/RH monitoring with easy reporting:

• Cold chain and logistics companies (refrigerated transport, distribution hubs)

• Pharmaceutical manufacturers, distributors, and cold room operators

• Vaccine storage and healthcare supply chain teams

• Food and beverage processors, exporters, and cold storage operators

• Laboratories, calibration/QA teams, and controlled environment facilities

• Greenhouse, horticulture, and controlled agriculture operators

• Warehouse managers for humidity-sensitive goods (packaging, electronics, chemicals)

• System integrators and facility managers needing downloadable audit reports

FAQ

Q1. What is the Elitech RC-4HC used for?
It is used to record temperature and humidity over time for storage and transport monitoring, especially in cold chain logistics, pharma, food, and laboratory environments.

Q2. Does RC-4HC measure both temperature and humidity?
Yes. It measures temperature and humidity using the internal sensor, and also supports a separate external temperature sensor for wider temperature range monitoring.

Q3. What is the temperature range of Elitech RC-4HC?
External sensor range is -40°C to 85°C. Internal sensor temperature range is -30°C to 60°C.

Q4. What is the accuracy of the Elitech RC-4HC data logger?
Temperature accuracy is ±0.5°C. Humidity accuracy is ±3%RH (at 25°C, 20–80%RH).

Q5. How many records can RC-4HC store?
It can store up to 16,000 groups of logged data (time-stamped records).

Q6. How do I download data and generate reports?
Connect via Micro USB and use ElitechLog software on Windows or macOS to export PDF, Excel, or TXT reports.

Q7. Does the device have alarms?
Yes. It has an LCD display and buzzer alarm to indicate temperature/humidity excursions beyond set limits.

Q8. Is Elitech RC-4HC suitable for vaccine storage monitoring?
Yes. Its accuracy and continuous logging make it suitable for vaccine and pharmaceutical cold chain monitoring when used as part of a validated storage process.

Q9. What is the protection rating of the device?
It has an IP64 protection rating, suitable for typical industrial storage and handling environments.

Q10. What battery does Elitech RC-4HC use?
It uses a 3.0V disposable lithium battery (CR2450). Battery life depends on the logging interval and alarm usage.
