Series BDL Button Data Logger
Specifications - Installation and Operating Instructions
Bulletin DA-USB
The Series BDL Button Data Logger records temperatures and humidi-
ty in applications where size and cost effectiveness are key. The BDL is housed
in a stainless steel case and is water resistant, making it durable in hostile
environments where excessive moisture is present. The BDL is self-powered
and features a USB interface. Sample rate and high/low alarms are user
selectable through the Windows
®
-based application. The included software
displays downloaded data graphically with trace and zoom functions. The
logger is very small which enables it to be inserted into small items and pack-
ages. The Series BDL-K Logger Kit includes 2 buttons, 2 magnets, an inter-
face cable, and a plastic button holder.
