The Additel 681 is an affordable compound gauge that's suitable for both vacuum and pressure applications, while also being very accurate (0.2%). Its accuracy is compensated even in temperatures that reach up to 50°C.
The Additel 681 Digital Pressure Gauges all function in the same manner, with the main difference between the them being the accuracy level (this particular model has an accuracy of 0.2%).
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 conveniently come with NIST calibration and battery operation, while data logging capabilities are available upon request.
Metric, NPT and BSP connections, data logging and panel mount are all available on request.
