These shirt-pocket-sized pressure calibrators can measure vacuum and pressure from zero up to pipeline pressures, and everything in between—without any external sensors! There are a variety of models to choose from. Model 31’s have one sensor, while Model 33’s allow you to combine two sensors into one calibrator. All 30 Series calibrators indicate milliamps.
• Calibration of all pressure devices of Transducer / Transmitter gauages, switches and etc.
• Suitable to use in all industry
