this calibration device is suitable for spot check, accuracy confirmation and volume calculation by manually adjusting the volume

volume variation: 0.1～5ml

this standard leak generates fixed flow under fixed pressure, and is suitable for spot check, accuracy confirmation and parameters setting

leak rate range: 0.1 ~ 200 ml/min

this standard leak has wilder flow range and applications and large flow type is optional

leak rate range: 0.2～100ml/min.

this standard leak has fast response and hardly be affected by the ambient temperature

leak rate range:
1x10-9～9x10-4pa•m3/s
pressure range：-0.1～2mpa

this compact calibrator is used for calibrating air leak tester and can generate any required leak rate

leak rate range：0.2～100ml/min

the pressure change resolution reaches up to 1pa

detectable range： 5×10-8～5×10-5pa.m3/s

this device is used to calibrate the leak detector, differential pressure gauge and pressure gauges

differential pressure range: 0～±2000pa
direct pressure range: 0～1000kpa3
