The user manual specifies 32,000 readings, while several current listings describe the capacity as 32,700; this appears to reflect different published specifications/versions, so 32,000+ readings is the safer website description. 

Data Logging

The Easy Log allows the user to select the measurement interval according to the application. Recording can be configured from once every second to once every 24 hours. This makes it suitable for both short-term investigations and long-term environmental monitoring. 

The logger can operate in different recording modes. When the memory becomes full, the selected mode can either stop recording or overwrite older readings with newer measurements. 

Alarm Function

High and low alarm thresholds can be configured for temperature and humidity. When a measured value exceeds a programmed limit, the alarm indicator provides a visual warning. Some versions also provide an alarm output connection. 

PC & USB Software

Recorded measurements can be transferred to a computer through the USB interface. The accompanying software allows users to:

• Download recorded measurements
• View temperature and humidity graphs
• View readings in text/data-list format
• Examine date and time information
• Save recorded datasets
• Export data to Excel
• Review logger settings and measurement parameters 

Display Information

The LCD can indicate:

• Current temperature
• Relative humidity
• Date and time
• °C/°F
• Battery status
• Recording status
• MAX/MIN status
• Memory-full status
• Recording mode
• Alarm status 

Applications

The HTC Easy Log is suitable for monitoring environmental conditions in:

• Pharmaceutical storage
• Cold-chain transportation
• Warehouses and storage rooms
• Laboratories
• Refrigerators and temperature-controlled areas
• Food and agricultural storage
• Blood banks and healthcare storage
• Greenhouses
• Telecommunication rooms
• Libraries and archives
• Museums
• Offices and buildings
• Logistics and transportation

It has also been used for recording temperature and humidity in scientific field environments. 

Standard Accessories

Depending on the particular package, the standard accessories include:

• HTC Easy Log data logger
• 3.6 V lithium battery
• USB cable
• PC analysis software
• Carrying/holding case
• Safety/combination lock
• User documentation 

Product Advantages

HTC Easy Log is particularly useful when environmental conditions need to be recorded over an extended period rather than simply viewed at the moment of measurement. Its large memory, adjustable sampling interval, alarm system and USB data transfer make it suitable for documentation, quality control and environmental monitoring.
