Digital pressure calibrator ConST273
The ConST273 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.

Digital pressure gauge ConST211
The all new ConST211 is a high-accuracy, high-resolution digital pressure gauge. Because of their robust design, these gauges meet stringent demands and can be used in critical industrial applications where particular importance is attached to measuring accuracy, reproducibility, long term stability and protection against dust penetration.
The ConST211 has an accuracy of 0.05% of the calibrated span which is fully temperature compensated across the range of -10°C to 50°C.

Marst gauge Pressure Range:
0 to 16 bar
0 to 40 bar
0 to 100 bar
0 to 250 bar
0 to 600 bar



Pressure test pump
The Model ConST131 Hydraulic Hand Pump is a dual pressure source with the ability to easily adjust and stabilize. This hand pump possesses both 95% vacuum and positive pressure 9000 psi; uses oil or deionized water as the media, and can adjust the pressure easily and stably.

In order to avoid the enhance pressure seal ability, the ConST131 didn’t use the check valve (non-return valve) but use the helicoidal pump, that makes the ConST131 is very easy for pressurizing and is much better than other pliers hand pumps.

The adjusting resolution is up to 100 Pa (1 mbar). These features make the CONST131 ideal for calibrating pressure transducers, precision pressure gages, and other pressure instruments.
