New wireless temperature and humidity transmitter is designed for fast, simple installation.

Vaisala has launched a new wireless version of its Continuous Monitoring System (CMS)* which allows secure monitoring, alarming and reporting of temperature, relative humidity, CO2, differential pressure, contacts and other critical parameters in Life Science applications. Thanks to its ability to connect to any existing network and therefore eliminating the need for any extra transmitter equipment, the new device-the Vaisala HUMICAP® Wireless Humidity and Temperature Transmitter HMT140-significantly reduces the costs of installation when compared to similar systems.

"The new Vaisala wireless system is simple to set up, because it disposes of the two most common problems with implementing a new monitoring system or even scaling up from an existing one, namely: the need to overhaul networks and install extra access points," said Jon Aldous, product manager for the new device.

"With the Vaisala HMT140, the sensor, memory, power and transmitter are all within a compact enclosure, making the system much easier and cost-effective to install and manage. With wireless networking quickly becoming the preferred mode of connectivity, this solution is a timely addition to our existing connectivity options."

The built-in transmitter of the new wireless solution communicates directly with the user's existing network so that there is no need to purchase and install extra transmitters when installing a new sensor. Nor is there any need to install and maintain a dedicated network, which is a huge savings in initial outlay for this type of system. The on-board memory provides point-of-measurement recording by Vaisala's best-in-class sensors so that data is protected from loss due to power failure or network downtime.

The Vaisala HUMICAP® Wireless Humidity and Temperature Transmitter HMT140 has a wide temperature operating range of -20°C to +60°C with display and -40°C to +60°C without display. The device can monitor up to two channels using either external or internal sensors. Compact and easy to place, the transmitter has an IP65 rated enclosure making it optimal for cleanroom environments. Internal batteries come with a 2-year life-span and the combined temperature/humidity sensor can easily be switched out to simplify calibration requirements.
