MEDM 500 and MEDM 5K

THE MICROPROCESSOR MANOMETERS

The MEDM 500 and MEDM 5k are precision microprocessor manometers providing direct digital readings of pressure, velocity and volume flow in both metric and imperial units. They can be used with Pitot Static Tubes, Flow Grids and other differential pressure sensing devices for which a ‘K?factor is known. Featuring automatic zeroing, as well as a range of temperatures and duct static pressures which may be entered to display compensated readings in line with the prevailing test conditions, thereby eliminating the need for tedious manual calculations. An 80 input memory with averaging facility is also incorporated to store multiple readings together with an analogue output to download information onto a data logger or compatible printer.

Available in two models, the MEDM 500 is designed for high accuracy low to medium range HVAC applications while the higher range MEDM 5k provides outstanding resolution for more general purpose measurements.

Clear precise instructions and data are displayed on the dot matrix screen with the MEDM’s user friendliness further enhanced by the touch sensitive control pad.

Calibrated to an Internationally recognised standard the MEDM 500 and MEDM 5K 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 MEDM 500 and MEDM 5K, 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.
