The series 30 Calibrator by is probably the greatest pressure calibrator on the market today. These calibrators are all you need in one tool. Small enough to fit in your shirt pocket, but big enough to handle all your calibration needs from 1 bar up to 200 bar, with a fantastic accuracy of 0.05% of reading. Yes of reading, So even at 4 bar (on at 20 bar sensor) you have a accuracy of 0.05% of 4 bar WOW!..

Also the unit will read milliamps for those pressure transmitters.

Each pressure sensor is isolated so you can use it on oil, water, air or nearly any process fluid that you will come across. No need to worry about using the 1 bar sensor on dirty water or oil. Another great feature is that they are Intrinsically Safe so you can use it in Hazardous areas.

Due to their small size and light weight they work well with our range of Ralston Hand Pumps. Install the Ralston QTHA-1MBA into each port and the QTHA-2MBO into your Ralston hand pump and away you go. Each series 30 calibrator is sold with a 3 year indestruct warranty, this warranty covers any damage regardless of cause for 3 years.

If your calibration work covers a wide pressure range then check out the series 33 which has two pressure sensors.
Plus each calibrator can be supplied with a IANZ endorsed calibration certificate for the pressure and a CPS validation of the mA.
Also this calibrator works fantastic with the Fluke 725 for all your electrical calibration work, what a fantastic combo.
