The HH-USD series has been discontinued. Please see the HHEM-SD1 Series as a possible alternative or contact our Flow Engineering department.

The HH-USD universal handheld test instrument is a highly versatile meter that offers the utmost flexibility and ease of user operation by having the capacity to work with a variety of compatible sensing modules and probes. Additional wired and wireless probes or modules are instantly recognized by the HH-USD without any user reprogramming or alteration, allowing seemless sensor addition, upgrade or replacement. The HH-USD offers a slew of features that enable a user to quickly set-up and intuitively navigate through their daily activities. Data is stored via the internal memory or separate SD card in various auto or manual logging operations. Logged files can be quickly transferred to a device through a USB cable or by a portable SD card. The bright OLED display can operate in standard numerical meter mode, gage mode with 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 aligning to corresponding screen functions, allow for quick navigation through the four main operation menus. The rugged plastic case with protective thermo-plastic over-mold, along with the dust-shielding rubber caps, permit the unit to handle abuse and properly withstand dusty environments. The base HH-USD 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 HH-USD provides means for 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. The rechargeable battery via the included USB cable provides long term operation to last through several days work. At just under 283 g (10 oz), the compact HH-USD base is lightweight. Included with the HH-USD is a soft carrying case which secures the provided accessories and added test probe.
