Temperature, humidity, barometric pressure, and mass values Isnt it troublesome to unify and process these data from different recording devices? The AD-1687 Weighing Environment Logger, which also detects vibration, is ideal for managing environmental conditions that influence the performance of precision analytical balances.

By simply connecting it to an A&D balance, the AD-1687 saves mass values sent from the balance while simultaneously collecting temperature, humidity, barometric pressure, and vibration data from the setup environment, all with date and time of recording. The AD-1687 can store up to 10,000 data sets in CSV format, which can be opened using common spreadsheet software for easy processing and graphing. You can also have the AD-1687 send data to a PC in real time without saving the data on the device itself.

The AD-1687 doesnt require battery power when connected to either a balance or a PC because it receives power directly from these devices. When used alone and operated on batteries, the AD-1687 saves power by automatically turning off after a set period of inactivity. (Only the display turns off while recording with the interval time setting.)

Depending on your purpose, you can set the AD-1687 to display either all data items or just two primary data items of your choosing. You can also choose to display data either numerically, or by trend graph, in which results are graphed using automatic scaling so that you can grasp chronological changes quickly and intuitively.

The AD-1687 is compact enough to be carried around and, with the protective cover, becomes IP65 dust and waterproof for use at various locations other than laboratories.
