Additel

Additel Corporation designs and manufactures pressure and temperature calibration instruments — handheld calibrators, digital gauges, automated pressure controllers, dry-wells, and related modules used in shops and in the field.

What Additel is known for

• Automated pressure controllers and documenting calibrators (ADT760 / 761 / 762 and related)
• Digital pressure test gauges (ADT680 / 681 / 685 / 686 families)
• Multifunction process calibrators (ADT226 / 227) and pressure modules (ADT161)
• Thermocouple calibration furnaces (ADT875 / 878) and handheld pressure generators

Additel pressure calibrators

These are the Additel pressure calibrators we carry, with figures as Additel specifies them:

• Additel 760 automatic handheld pressure calibrator: built-in electric pump and controller, so you key in a setpoint and it generates pressure. Under 4 lb, accuracy as low as 0.01% FS, generation to 375 psig on the ADT760A, and optional HART, documenting and data logging (-DL).
• Additel 761 automated pressure calibrator: pneumatic, with a built-in pump that generates and holds each setpoint (to 1,500 psi on the 761A).
• Additel 762 automated pressure calibrator: hydraulic, with a built-in electric pump that generates and controls to 15,000 psi (1,035 bar) at 0.01% FS.
• Additel 673 advanced digital pressure calibrator: color touchscreen, mA/V measurement with 24 V loop power, optional full HART, IP67, and ranges to 60,000 psi.
• Additel 273Ex intrinsically safe handheld pressure calibrator: multifunction, with a built-in barometer, dual external module inputs and optional HART.
• Additel 715 precision pressure indicator: a benchtop reference (0.01% RD option, 2 to 15,000 psi ranges) that reads pressure but does not generate it.
• Additel 710 automatic gauge reader: automates dial and digital gauge calibration when paired with an Additel pressure controller and ACal software.

To generate pressure for a calibrator without a built-in pump, see hand pumps and test pumps. Compare Additel with Crystal and Mansfield & Green on the pressure calibrators page.
