BetaProbe TI/TI+

High Accuracy

Digital Thermometer

User Reference Manual

1. Introduction

The BetaProbe TI/TI+ is designed to be a high precision digital
thermometer that can be used in place of mercury liquid in glass (LIG)
thermometers. It can also be used as a reference standard to check the
accuracy of other types of digital or analog thermometers. Because of its
intrinsically safe certification it can be used in many of the same
hazardous locations as analog thermometers.

The probe houses a fast responding thin film (TI) or wire wound (TI+)
sensor that allows very accurate readings to be taken quickly and with
minimal insertion depth.

A rotatable probe mount allows for both horizontal and vertical
orientation of the display module.

A unique feature of the BetaProbe TI/TI+ is the trend indication arrows
which the user can configure to show when the readings are considered
to be stable enough to record the reading.

Additional features such as min/max storage, selectable sample rate,
auto-shutoff, backlight and damping allow the user to tailor the TI/TI+ for
their specific application.

Battery life is up to 300 hours. With the auto-shutoff feature the typical
user may only have to change the batteries a few times per year.
