LittleBear - Temperature Logging Verification System

PDF datasheet and reference files.

Description. LittleBear is a compact, battery-powered, NIST-traceable, laboratory temperature measurement device with 0.1 °C accuracy over an unusually broad range: -55 to 85 °C.  It has enough

battery capacity and memory storage to log data for months.  Data are time stamped.  It uses a USB-C

interface to extract data. BOE’s free EasyPlot app may be used to archive data in spreadsheet or PDF

form. This combination will satisfy the most rigorous standards of ISO 17025, GMP, GLP, and USP.

LittleBear is designed for use in the laboratory, in industry, and in the field.  User settings are easily

programmed.  The case may easily be mounted to a surface.  Its compact size lets it hide

away discreetly in a corner while it does its job.
