CUSTOM Data logger multi-function environmental measuring instrument AHLT-102SD

A multi-functional environmental measuring instrument that can measure wind speed, illuminance, temperature, and humidity and record data to an SD card.

• By connecting an optional K-type/J-type thermocouple sensor, it is also possible to measure thermocouple temperature and record data to an SD card.
• The recorded data can be used with commercially available spreadsheet software, making it suitable for a variety of purposes.
• Data recording can be selected from automatic recording or manual recording.
• The sampling time of the automatic data logger can be set to any of the following: 1, 2, 5, 10, 30, 60, 120, 300, 600, 1800, or 3600 seconds.
• Comes with a green backlight function that makes it easy to see even in dark places.
• Equipped with a hold function that temporarily freezes the measurement value on the display.
• Comes with a MAX (maximum value)/MIN (minimum value) display function for measurement values.
• To prevent battery drain, the device is equipped with an auto power off function that automatically turns off the power if the device is not operated for a certain period of time.

Measurement results can be recorded by inserting an SD card.

The data recorded on the SD card can be imported into spreadsheet software such as Excel as a CSV file.

About SD cards

• Although commercially available SD cards (1-16GB) are compatible, operation has not been certified for all SD card products from all manufacturers. Please note that some SD cards may not be compatible.
• The SD card is not included and must be purchased separately.
• Other types of memory cards, such as SDXC cards and MMC cards, cannot be used.
• SDXC and SDHC are registered trademarks of the SD Association.

Precautions when using a light meter

• Illuminance meters are calibrated using a filament-type light bulb known as a standard light bulb as a standard light source. Fluorescent lamps and LED lighting, which are commonly used in general workplaces, have different wavelengths of light compared to standard light bulbs, so measurements may differ.
  In such cases, it may be necessary to take measures such as measuring with multiple illuminance meters (different models from different manufacturers) and taking the average value.
