The Additel 681 is an affordable compound gauge that's suitable for both vacuum and pressure applications. This particular unit contains the highest accuracy level of 0.02%, along with its accuracy being compensated in temperatures that reach up to 50°C.
This particular model stands out from the other 681 Pressure Gauges, as it's able to measure pressure at an incredible accuracy level of 0.02%, which is the highest available.
The easy to use 681 series pressure gauges have a wide variety of uses, as it's equipped with both vacuum and pressure reading abilities (-100 - 2000kPa respectively). Its also able to safely operate in temperatures from -10°C and up to 50°C.
All of the Additel 681 series are battery operated, while they all conveniently come with NIST calibration, a backlit display and 11 selectable pressure units.
Metric, NPT and BSP connections, data logging and panel mount are all available on request.
