AD-1687 weighing environment logger, from A&D

A&D has introduced the AD-1687 weighing environment logger that can simultaneously and chronologically record weighing values as well as temperature, humidity, atmospheric pressure and vibration.

When connected to a weighing instrument, weighing data (zero point and weight value) and time, temperature, humidity, atmospheric pressure and vibration are simultaneously recorded each time the print key is pressed. Even when the logger is not connected to a weighing instrument, it can be used to log environmental data in locations ranging from cleanrooms and labs to production facilities.

By connecting the AD-1687 to a PC, recorded data can be imported into software, such as Microsoft Excel, for data analysis, without using special data transfer software. When connected to a PC, the PC recognises it as USB storage.

Data trends can be graphed using automatic scaling and the display of environmental data can be limited to, for example, temperature and humidity. Acquired data, saved to a PC, can be used to calculate span values and repeatability from span values.

Designed to be compact, portable and rugged, it has an IP65 waterproof construction (main unit) and enough shock resistance to avoid breakage from falls from as high as 1.5 m, making it suitable for applications such as the measurement of factory wastewater and various other difficult measurement situations.
