AND AD-1687 Weighing Environment Logger

AND AD-1687 Weighing Environment Logger

Product Overview: AND AD-1687 Weighing Environment Logger

The AND AD-1687 is a versatile and robust data logger designed to simultaneously capture and record both weighing data from a scale and environmental conditions. It integrates four key environmental sensors—temperature, humidity, barometric pressure, and vibration—into a single, compact unit. With a large memory capacity and an IP65 dust/waterproof rating, it is an essential tool for quality control, research, and manufacturing processes where understanding the impact of the environment on weight measurements is critical.

Key Features & Capabilities

• Comprehensive Data Correlation: Simultaneously records weight data from a connected weighing instrument and four types of environmental data (temperature, humidity, barometric pressure, vibration) with a single time stamp.

• High-Capacity Memory: Stores up to 10,000 data sets, ensuring long-term logging for extended experiments or monitoring periods.

• Plug-and-Play Data Transfer: Saves data instantly to a PC via the included USB cable without requiring any special software; appears as a removable drive for easy file access.

• Multiple Power Options: Can be powered by two AA batteries, or directly via the RS-232C connection from a weighing instrument or the USB connection from a PC, eliminating battery dependency during connected use.

• Rugged IP65 Construction: The dust-tight and water-resistant design (protected against water jets) allows for reliable use in various challenging environments.

• Flexible Display Modes:

  • Primary Data Mode: Allows you to customize the display to show only the two most important data items.

  • Trend Graph Mode: Visually displays chronological changes in data using easy-to-read graphs.

• Versatile Connectivity: Comes standard with three different RS-232C cables for compatibility with a wide range of AND weighing instruments, plus a USB cable for PC connection.

• Long Battery Life: Offers approximately 6 months of operation on alkaline batteries with a 1-minute measurement interval, supported by a power-saving function and a remaining battery level indicator.
