August 04, 2020

Brands:Additel

SKU:

ADT681-CP-DL

The Additel ADT681-DL data logging digital compound pressure gauges, provide an accurate, reliable and economical solution for a wide range of pressure applications. With accuracy choices of 0.2%, 0.1%, 0.05% & 0.02% of full scale or 0.1% reading and compound pressure ranges from -100 kPa to 2,000 kPa, there are options to meet all budgets and service requirements.

 

The ADT681-DL incorporates onboard datalogging and can be used with the free Additel Land software for setting up and retrieving results from the gauge or be used with optional Log II software for real time logging requirements.

 

The ADT681-DL digital pressure gauge is supplied with ISO17025 accredited calibration certificate. Zedflo is a NATA accredited facility and can provide accredited calibration for these products.

 

The ADT681-DL has options for measuring gauge, compound, differential, absolute and barometric pressure.
