Additel 761A
Automated Pressure Calibrator (Up to 1500 psi)
The 912A Pneumatic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 95% vacuum to 60psi (4bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar). The 912A is a very stable low pressure calibrator. It makes use of an isothermal bellows chamber which is designed for reducing the possible effects of environmental temperature change. Most pumps make use of a check valve (non-returning valve) and are not well insulated which will cause large fluctuations in pressure with a change in ambient temperature or when the unit is touched. The 912A does not use a check valve and is remarkably stable. Two hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 912A is an ideal comparison test pump for low pressure application.

Additel 760
Automatic handheld pressure calibrator (Up to 300 psi)
The Additel 760A is a high-performance automatic handheld pressure calibrator designed for precision and portability in the field. Weighing less than 4 lbs (1.8 kg), this integrated device replaces bulky manual pumps with a built-in electric pump, internal controller, and a precision pressure sensor. Optimized for instrumentation technicians, the ADT760A offers a seamless user interface via a new capacitive touch screen, allowing users to generate and control pressure by simply entering the desired setpoint. With four distinct channels, including internal pressure, external pressure (2 channels) and electrical measurement, it serves as a comprehensive tool for pressure calibration and maintenance of critical process infrastructure.
