Testo 0554 1106 Usb Power Supply with Cable

Product Description

The TESTO 0554 1106 is a USB power supply with integrated cable designed to provide reliable, continuous power to compatible TESTO measurement instruments. Built for field and bench use, this power supply eliminates reliance on battery power during extended data logging sessions or active measurement workflows. HVAC technicians and IAQ specialists who run long-duration tests benefit from uninterrupted instrument operation when connected to a USB power source such as a laptop, USB wall adapter, or power bank. The unit connects directly to the instrument without additional adapters, keeping the setup clean and straightforward.

This power supply is suited for indoor air quality (IAQ) assessment work and ventilation system commissioning where instruments must remain powered for extended periods. It is compatible with the Testo 400 multifunction IAQ instrument and TESTO IAQ data loggers. Technicians conducting building diagnostics, commissioning HVAC systems, or performing ASHRAE 62.1 ventilation verification will find this accessory useful for keeping instruments live throughout the job.
