A new product for measuring relative humidity
The Vaisala HMT320 series includes six interchangeable probes, a separate transmitter body and mounting plate for humidity measurement in process and environmental test applications
Portable meter for oil moisture
The Vaisala Humicap hand-held moisture and temperature meter for oil, type MM70, detects moisture in lubrication, hydraulic and transformer oils: it is ideal for in-line moisture monitoring
The DMT345 probe is designed for direct measurement in temperatures up to 180C.
The optional installation flange allows for adjustable installation depth and therefore precise positioning.
In addition to measuring dewpoint and mixing ratio, the DMT345 measures temperature and relative humidity.
The DMT346 probe is constructed for humidity measurement in process temperatures between 140C and 350C.
The DMT346 comes with a cooling set as a standard accessory.
System cooling is accomplished without moving parts, additional power or cooling utilities.
This removes the risk of damage to the transmitter that may occur due to cooling failures.
The DMT345 and DMT346 incorporate the latest generation of the Vaisala Drycap Sensor, which provides accurate and reliable measurement with the best long-term stability and fastest response time available in the market.
The sensor recovers quickly after getting wet and is immune to particulate contamination, condensation, oil vapour and most chemicals.
Due to the patented auto-calibration feature, both transmitters have a low maintenance need.
The auto-calibration detects on-line possible measurement inaccuracies and automatically corrects dry-end drift in calibration.
The large numerical and graphical display with a multilingual menu allows the user to monitor operational data, measurement trends and up to 1-year measurement history.
Typical applications for the Vaisala Drycap dewpoint transmitters DMT345 and DMT346 include high temperature ovens in the food industry and high temperature drying in the process industry.
