Portable, Precise, Pressure Readings

The PVM50 micromanometer is a compact, hand held instrument designed to measure pressure and air velocity, quickly and easily at the push of a button.

This stylish meter is one of the lightest of its type and contains up to the minute microprocessor technology ensuring superb accuracy at all times. Combining the benefits of convenience and speed of use with simple one handed operation PVM50 is the perfect choice for a wide range of air measurement applications.

Readings in either metric or imperial display appear on the large clear LCD. With direct readings of both pressure or air velocity the requirement for further complex calculations is significantly reduced. PVM50 is also one of the few portable electronic manometers currently available, which in addition to differential pressure, can measure positive and negative pressure with equal accuracy and without having to reverse the pressure tube connections.

Outstanding accuracy is also a feature of PVM50 with high resolution across a wide measuring range, enabling low pressure applications to be measured with excellent accuracy as well as higher pressure systems. Automatic zeroing is also very important in allowing the operator to check the accuracy of the meter. This quick check only takes about 5 seconds to complete and re-enforces both user and client confidence in the test data.

Calibrated to an Internationally recognised standard the PVM50 is supplied with a FREE TRACEABLE CERTIFICATE OF CALIBRATION and a reply card is also included for purchasers to register with our FREE annual calibration reminder service.

All Airflow?Instruments, including the PVM50 are designed to help meet the stringent requirements of the Control of Substances Hazardous to Health (COSHH) and Building Regulations in the UK.

For our UK customers the reminder card service ensures valid certification for COSHH, ISO9001 and Quality Assurance requirements.
