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 ±1 bar
0 to 1.6 bar
0 to 4 bar
0 to 10 bar
0 to 25 bar


Pressure test pump
The Model ConST116 Pneumatic Hand Pump is a dual pressure source with the ability to easily adjust and stabilize. This calibration pump possesses both 95% vacuum and pressure 375psi; uses air as the media, and can adjust the pressure easily and stably. Since it is attached inner gas-liquid isolator and shut-off valve (for releasing dirt), ConST116 is totally free from humidity and dirt. Because ConST116 is airtight and durable, it is entirely better than other pliers hand pumps more much.
.The adjusting resolution is up to 0.01 Pa (0.0001 mbar). These features make the CONST116 ideal for calibrating pressure transducers, precision pressure gages, and other pressure instruments.
The patent right number of ConST116 is ZL 2008 2 0123201.0, const group reserved.
