ADT680W-CP Digital Pressure Gauge – Compound Pressure Data Logging

September 09, 2020


The Additel ADT680W digital pressure gauges, provide an accurate, reliable and economical solution for a wide range of pressure applications. Rugged and IP67 rated they are ideal for all field and lab testing purposes. With accuracy choices of 0.25%, 0.1% % & 0.05% of full scale and compound pressure ranges from -100 to 200 kPa, there are options to meet all budgets and service requirements.


ADT680W incorporates wireless 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 wireless software for real time logging requirements. Wireless communication allows multiple gauges to be connected to PC simultaneously.


The ADT680 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 ADT680W has options for measuring gauge and compound pressure.
