THE STANDARD IN PRECISION MEASUREMENT

Introduction

The Digi-Sense Mini Particle Counter with Bluetooth®
Connectivity (model 20250-65) allows you to transmit data
directly to your Android
D/S Particle mobile app. Now you can view data at a safe
distance from potentially hazardous parameters or even
use your smart device as a real-time secondary display for
checking measurements, eliminating the need to write
down readings on paper. The results are automatically
stored in the app with a date-and-time stamp and can be
saved as a CSV file and emailed for future reference,
manipulation, or analysis to help determine trends and
conditions over a long period of time. You can also use the
app to attach photos and notes to the records creating a
clear reference point for your work.

Setup is simple. Download the free D/S Particle app to
your Android or iOS device. Place the particle counter in
Bluetooth mode and open the app on your device. The
counter will be sensed by your device and be listed as an
available source that you can select. Once selected, the
measured data is displayed on your smart device and
some of the instrument functions can also be accessed.
A full description of its operation is available for download
in the app.

This handheld mini particle counter provides fast, easy
and accurate readings for particulate counts, particle mass
concentration, air temperature, and relative humidity. Real­time measurements can be displayed on 2.0" color TFT
LCD or recorded in memory. Proper use and care of this
device will provide many years of reliable service.
