• Position the logger at a representative monitoring point away from direct sunlight, heaters and concentrated ventilation airflow.
• Connect the optional external temperature probe securely when remote temperature measurement is required.
• Use the magnet, hook-and-loop fastener, screw or mounting bracket according to the installation location.
• Download and archive recorded data regularly when long-term environmental traceability is required.
• Keep the sensor openings clean and unobstructed.
• Avoid direct immersion of the logger or exposure to corrosive cleaning chemicals.
• Replace the battery when the low-battery indication appears or before critical long-duration monitoring projects.

Q: What does the RC-4HC record?
A: It records environmental temperature and relative humidity at programmable time intervals.

Q: What is the temperature range?
A: The built-in sensor typically measures from -30°C to 60°C, while the optional external temperature probe extends the range to approximately -40°C to 85°C.

Q: What is the humidity range?
A: The specified relative humidity measurement range is 0% to 99% RH.

Q: How many records can the logger store?
A: The RC-4HC can store up to approximately 16,000 records depending on the configured recording mode.

Q: Can the recording interval be changed?
A: Yes. The logging interval can be configured from approximately 10 seconds to 24 hours.

Q: Can recorded data be transferred to a computer?
A: Yes. The logger connects through USB and compatible software can be used to download, analyze and export monitoring records.

Q: Does the unit support environmental alarms?
A: Yes. Alarm limits can be configured for temperature and humidity, with visual and audible indication when specified conditions are exceeded.

Q: Can an external temperature probe be used?
A: Yes. An external temperature sensor is available for applications requiring remote measurement or a wider temperature range.

Q: Is the RC-4HC suitable for livestock farms?
A: Yes. It can be used for environmental monitoring and record keeping in pig houses, poultry houses, feed rooms, medicine storage areas and other farm facilities.
