Additel ADT681IS


Intrinsically Safe Digital Pressure Gauges



With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the 681IS series digital pressure gauges provide an accurate, reliable, and economic solution for a wide range of pressure applications. They are loaded with functionality and remarkably easy to use. To reach the best performance, every silicon pressure sensor in Additel's gauges is specially aged, tested and screened before assembly. At Additel, fully temperature compensated accuracy means every sensor is pressure tested at several environmental temperatures from -10°C to 50°C. With this test data individual coefficients are generated and stored in the gauge characterizing its performance over the full temperature compensated range. And now the ADT681IS comes with an IP67 rating meaning it is dust resistant and water proof, submersible in 1 meter of water.

Designed to fit your needs

Additel pressure gauges give you a wide variety of sensor choices. Whether you require low inches of water measurement or very high pressure measurement, Additel has a gauge that will meet your needs. They offer sensors which are ±1 inH2O (±2.5 mbar) to 60K psi (4,200 bar) and everything in between. Do your applications require you to measure both positive and vacuum pressure? Additel's compound gauges do not compromise accuracy and provide you with the same high accuracy specification on both positive and vacuum pressures; they also offer ranges up to 300 psi (20 bar). ADT681IS come with absolute pressure sensors to 5K psi (350 bar), as well as a full range of differential pressure sensors from ±1 inH2O (±2.5 mbar) to ±300 inH2O (±700 mbar). Are you looking for a pressure gauge to use in hazardous areas? Additel's certified (ATEX, CSA US and IECEx) intrinsically safe models are designed for pressure measurement in hazardous areas.

If you need to panel mount our sensors, Additel offers the option a back-mounted pressure port and gauge housing designed to fit in a panel. And most recently, they have added the option to do stand-alone data logging. Now you can record more than 21,000 records internal to the ADT681IS series. Each record includes date, time, pressure and temperature readings. Download the logged data with our free Additel/Land software or you can purchase our Additel/Log II for real-time logging and data analysis.
