GrayWolf’s DP-702LH differential pressure sensor, when installed in an AdvancedSense (or WolfPack®) meter, provides unprecedented accuracy plus range by auto-ranging dual sensors, as well as auto-zeroing (to maintain low-end precision). GrayWolf offers instruments with broad measurement ranges, yet exceptional sensitivity (all with auto-zeroing). They may be utilized for spot checks and for long-term trending of a variety of pressure measurement applications that require high reliability. Choose from the cutting edge AdvancedSense or the workhorse Zephyr Classical Line Meter.

Differential pressure is a key HVAC measurement parameter in commercial, residential and institutional facilities and in manufacturing plants. For example, measuring pressure drop across coils and filters identifies when cleaning or replacement is in order, leading to improved occupant air quality and to significant energy savings.
