The AT273 is a microprocessor controlled, precision
instrument powered by an internal Li-ion battery or external 10V
specified AC adapter. It is portable and capable of accurate pressure
instruments and sourcing when calibrating transducers, pressure
switches, etc.
Advanced silicon technology delivers 0.02%F.S accuracy over
ranges to 600 bar, 0.1%F.S accuracy over ranges to 2500 bar,
permits use in most environments without degradation of accuracy.

Applications:
●Burst Disc testing.
●Safety relief valve resting
●Hydraulic torque wrench indication
●Pressure regulator testing
●Gauge calibration
●Pressure regulator adjustment
●Filter performance testing
●Hydraulic leak testing
●Pressure switch testing
●Wellhead monitoring

Features:
◆HART Communication ability;
◆Data logger: big capacity of data store (total 1200
data) and real time record; manual or automatic mode can be selected.
◆High stability: through a rigorous test of
artificial accelerated aging, stress aging test and use an unique
temperature compensation technology to ensure the
0.02% accuracy (20°C ± 3°C).
◆Self-protection: Strict protection of electrical
design make AT273 has sup er self -protection abi lity.
◆Safe battery: Polymer Li-ion rechargeable battery.
◆Electro Magnetic compatibility (EMC) ability
◆RS232 Connect: baud rate & address can be found;
◆High-accuracy sampling data: the resolution can be
switched to 5 digits or 6 digits;
◆Pressure peak value record function;
◆Pressure leak hunting function;
◆Set pressure triggering switch status;
◆Real time o’clock function;
◆Single-key shortcut operation
◆The test leads can be interchanged on Standard
electricity terminal;
◆Big LCD screen with blue backlight: dual lines with
6 digits, real time and measuring percentage indication.
