Electronic Manometry in the 21st Century

The Comdronic AC7-HP+ is an electronic manometer which is designed to measure differential pressures – within the range of 1 kPa to 800 kPa – Simplicity and sophistication in a single meter for commissioning water-based HVAC systems.

Extensive Valve Database – At Your Fingertips!

The performance characteristics of over 5,000 valves – from 70+ manufacturers – are pre-programmed into the AC7-HP and this extensive knowledge-base is continually being updated as new valves are introduced onto the market. Valve data files are automatically updated whenever an AC7-HP is serviced by us.


A nine-button navigation keypad couldn’t be simpler to use. Screen backlights ensure that readings are always easy to read, even in the darkest of areas


The use of of industry-leading pressure sensors gives extremely high measurement accuracy. Bespoke firmware delivers a powerful, flexible, easy-to -use tool for the discerning commissioning engineer


Lightweight, portable and compact. Supplied in a robust carry case, complete with quick-release connection hoses, Binder-style connection adaptors, tools and comprehensive instrumentstions.

Over 5,000 valves and measuring devices from 70+ manufacturers worldwide.

HIGH PRESSURE manometer 1-800 kPa differential. The Comdronic AC7-HP meter is an electronic manometer programmed to carry out differential pressure measurements primarily on balancing valves within the HVAC industry. On board extensive database of the world’s balancing valves allows direct reading of flow, differential pressure, percentage of design flow and target flow. The nine button design allows simple navigation of the easy to follow menu system with all parameters visible on screen. System accuracy is by the use of carefully selected sensors protected by DSP Technology with resolution and accuracy most appropriate to the range of differential pressures being measured. The use of sophisticated electronics and highly successful mechanics removes the need for cumbersome ‘water boxes’ with their poisonous and inconvenient fillings. Pressure differential ranges are more suited to modern systems with higher differentials being measured across Diff controllers and some automatic balancing valves. Combining this with a database of over 5000 balancing valves from 70+ manufacturers the AC7 is the obvious choice for the modern commissioning engineer. The compact and lightweight AC7 includes transducer/display unit, snap connector anti kink tubing with isolation valves, snap connectors for most valves, protective rubber boot, toolkit, quick reference guide and instruction manual.


With a bespoke 3D-printed enclosure and additional internal design features, the AC7-HP+ is specially designed for use in extremely high ambient temperatures & relative humidities. The rugged construction of the AC7-HP+ also enables differential pressure measurements to be taken up to a maximum of 800 kPa. This product is all about delivering reliable, long-lasting performance in the most taxing of working environments.

Display Options

DP & Flow Display — shows differential pressure and flow, along with details of the target valve/device. Normally the most appropriate display option when taking measurements from fixed-orifice & variable-orifice balancing valves.

Advanced Display — shows more complex commissioning data and may be preferred to the DP & Flow Display if automatic balancing valves are being measured or if a system of proportional balancing is being adopted.

DP Only Display — only shows the measured differential pressure – in large text – and may be preferred when the AC7 is being used as a simple manometer.

Velocity (Flushing) Display — shows the derived velocity – in both metric (m/s) and imperial (ft/s) units – and may be preferred when fluid velocities are being measured for the purposes of system flushing.


Choose between English, French, Italian & Spanish for the displaying of available menu options.

Security PIN Code

As per user-preference, set an optional security PIN Code, which will asked for after every battery change.


For Differential Pressure, choose your preferred units from: kPa, psi, bar, cmH2O, IWGA (inches water gauge), Ft HD (feet head) or Pa.

For Flow, choose your preferred units from: l/s, l/m, l/h, USGPM, UKGPM, m3/h, m3/m or m3/s.

Valve Database

Over 6,000 valves and measuring devices from 80+ manufacturers.
