Testo 6621 temperature and humidity transmitter

The Testo humidity sensor is now available in a simple yet stylish HVAC transmitter.

For years, Testo has been the first choice when it comes to high specification humidity transmitters for drying processes and critical ambient condition monitoring.

With the new Testo 6621, this sensor and electronics know-how is now available in a low cost package for more general HVAC building control applications.

The attractive "architect friendly" design is the perfect solution for monitoring temperature and humidity in buildings whether mounted on a wall or in a ventilation duct.

The Testo humidity sensor: excellent long term stability.

Operators, facility managers, and plant engineers recognise the importance of long-term measurement stability.

Undesirable ambient conditions as well as higher operating costs are incurred if humidity measurement goes out of control.

The long term stability and accuracy of the industry leading Testo humidity sensor at the heart of the 6621 has been proven time and time again and demonstrated by numerous independent laboratory studies.

Quick and simple commissioning.

Installing the Testo 6621 is as easy as 1,2,3 thanks to the intelligent design of the transmitter housing.

Commissioning large scale projects is fast and straightforward with Testo's P2ATM software which allows easy set up and configuration of units and output scaling.

With a USB multi-port hub, multiple transmitters may be programmed simultaneously saving the installer valuable time and reducing installation costs.

The P2ATM software also allows you to track the complete performance history of each transmitter allowing you to review and verify service history and even analyse min/max values for an entire HVAC system.

Easy on-site adjustment: Fast and accurate with the use of an external interface.

On-site adjustment is fast and easy using one of Testo's handheld reference instruments.

Simply connect directly to the socket on the side of the 6621 using the interface cable and the handheld meter takes care of the rest.

No need to open up the transmitter, remove or uninstall and no need to send units off site to a calibration laboratory or back to the factory.

World first.

Not only offering both easy commissioning and onsite adjustment with attractive housing, but with pricing starting from just GBP105 the Testo 6621 HVAC Transmitter is an world first.
