With its advanced microprocessor technology and advanced silicon pressure sensors, the ADT681 series of digital pressure gauges offers an accurate, reliable and economical solution for a wide range of pressure applications. They are packed with functionality and are remarkably user-friendly. To achieve the best performance, every silicon pressure sensor in our gauges is specially aged, tested and screened before assembly. Fully temperature-compensated accuracy at Additel means that each sensor is pressure tested at various ambient temperatures from -10°C to 50°C. With this test data, individual coefficients are generated and stored in the meter that characterise performance over the full temperature-compensated range. And now the ADT681IS is IP67-rated, meaning it is dust- and waterproof and can be submerged in 1 metre of water.
Designed to meet your needs
Additel pressure gauges offer you the widest choice of sensors on the market. Whether you require low water pressure measurements or very high pressure measurements, we have a gauge to suit your needs. We offer sensors from ±1 inH2O (±2.5 mbar) to 60K psi (4,200 bar) and everything in between.
Do you need to measure both positive and vacuum pressure for your applications? Our composite gauges do not compromise accuracy and offer you the same high accuracy specification for both positive and vacuum pressure. We offer a wide range up to 300 psi (20 bar). If you need a higher range, contact us and we can probably customise one to meet your needs. We also offer absolute pressure sensors up to 5K psi (350 bar) and a full range of differential pressure sensors from ±1 inH2O (±2.5 mbar) to ±300 inH2O (±700 mbar). Looking for a pressure gauge for use in hazardous areas? Our certified (ATEX, CSA US & IECEx) intrinsically safe models (681IS) are designed for pressure measurement in hazardous environments.
If you need to mount our sensors on a panel, we offer the option (see ordering information) for a rear pressure port and gauge housing designed to fit into a panel. And recently we added the option to do stand-alone data logging with theADT681 series of digital pressure gauges. Now you can record more than 21,000 records internally with the 681 series. Each record contains date, time, pressure and temperature measurements. You can download the recorded data with our free Additel/Land software or you can purchase our Additel/Log II for real-time logging and data analysis. The ADT681 series of digital pressure gauges are unmatched in performance and reliability. Moreover, they are very affordable.
