Bulletin TE-UHH

he Model UHH Universal Handheld Test Instrument is a highly versatile

T

instrument that offers the utmost flexibility and ease of user operation by having
the capacity to work with a variety of Dwyer Instruments, Inc. compatible sensing
modules and probes. Additional wired and wireless probes or modules are
instantly recognized by the UHH without any user reprogramming or alteration,

llowing seemless sensor addition, upgrade or replacement. See the AQTI Series

a

n the Dwyer Instruments, Inc. catalog or website www.dwyer-inst.com for

i

vailable packages and sensors.

a

The Universal Handheld offers numerous features that enable a technician to
quickly set up and intuitively navigate through their daily activities. Data is stored
via the internal memory or a separate SD card in various auto or manual logging
operations. Logged files can be quickly transferred to a PC or laptop through a
USB cable or by a portable SD card. The display can operate in standard
numerical meter mode, gage mode with an analog needle, gage mode with
additional pass/fail operation zones, and strip chart mode which enables a
simplified visual tracking of the process. The four directional buttons, combined
with the three soft key buttons that are aligned to corresponding screen functions,
allow for quick navigation through the four main operation menus.

The rugged plastic case, with protective thermo-plastic over-mold and the dust­shielding rubber caps, permit the unit to handle abuse and properly withstand
dusty environments. The base UHH includes an integral molded compartment that
securely holds wireless modules. The storage compartment offers convenient
transportation of a module with the base instrument during testing. A flexible hand
strap, included with every UHH, allows the base handheld to be safely connected
to a belt, pipe, ladder or similar structure freeing the user's hands to focus on the
sampling test. A 6-pin connector enables one wired probe at a time to be plugged
in to the base instrument without worry of becoming disconnected during sampling.
Additional wireless units can be paired to the base handheld allowing users to
quickly switch between multiple parameters that need to be measured.

The rechargeable battery via the included USB cable provides long term operation
to last through several days of work. At just under 10 oz, the compact UHH base
is lightweight. Included with the UHH is a soft carrying case, universal office / car
charger, and USB cable.
