Additel Automated Pressure Calibration

Additel ADT761 Pressure CalibrationThe ADT761 series of calibrators perform automated pressure calibration in the field or the lab with high-level functionality. The 761 offers a revolutionary combination of pressure generation, control, and measurement in a compact package. Models come with an internal, high-performance electronic pump and precision pressure controller. No manual pressure generation is needed. They calibrate gauges, transmitters, and switches with superior accuracy. This portable calibrator series offers:

  • Pressure generation from 90% vacuum to 600 psi automatically
  • 0.005% FS pressure control stability and 0.02% FS accuracy
  • Additel ADT761-LLP for low pressure calibration
  • Additel ADT761-BP for barometric gauge calibration

The 761 series also features HART communication capability, supplies 24V loop power, and reads current or voltage.

Additel Digital Pressure Gauges

Additel 681Wide-ranging pressure solutions are found with the Additel ADT 681 Digital Pressure Gauges, which are available in four accuracy classes. Each user-friendly model features advanced microprocessors and silicon pressure sensors. The 681 models deliver temperature-compensated accuracy and reliability in more pressure applications. Use the precision gauge to perform field gauge calibration, as well as safety valve and regulator testing. The 681 model’s functionality includes: 

  • Pressure ranges to 40,000 psi
  • Eleven selectable pressure units
  • Large, easy-to-read, backlit display
  • Comprehensive data logging

Intrinsically safe versions of the Additel 681 gauges are also available.

Additel High Resolution Pumps

Additel ADT918 Pneumatic Pressure Test PumpGenerate pressure from 95 percent vacuum to 1,500psi with a lightweight, high-resolution pump that boasts an operator-focused design. The Additel ADT918 Pneumatic Pressure Test Pump features fine pressure adjustment capabilities and a shut-off valve that supports stability during calibration. Built for low maintenance, the hand-operated pump allows for easy connections and disconnections, with no wrench required!

Additel ADT920 High Pressure Test PumpThe Additel ADT920 High Pressure Test Pump shares the 918’s beneficial features and functionality. It is also a hand-operated pump, but with a pressure generation range up to 3,000psi, which can be reached quickly – in just 40 seconds. The 920 has an adjustment resolution up to 10 Pa. Both the Additel 918 and 920 serve as reliable comparison test pumps during the calibration of pressure gauges, transmitters, and other pressure instruments.
