The Vaisala DRYCAP® Dewpoint Transmitter DMT242 is the ideal choice for industrial applications where there is a need to control dryer performance in low dewpoints.
The DMT242 incorporates Vaisala’s DRYCAP® thin-film polymer sensor and auto-calibration software, a combination that makes it ideal for use in dry ambients. The transmitter provides long-term stability, fast response time and a wide measurement range with an accuracy of ±2 °C.
The DRYCAP® thin-film polymer sensor is immune to water condensation, particular contamination, oil vapors and most chemicals. Vaisala’s unique auto-calibration software corrects the possible dry end error and provides long term stability in dry conditions. Since the DMT242 transmitter can withstand even 100% condensation, its performance is unmatched for low dewpoint applications that may experience process water spikes.
The DMT242 is both compact, rugged and easy-to-use. The mechanics have been designed for extreme conditions that require protection against dust, dirt and splashed water. The housing is NEMA 4 (IP65) protected and the transmitter can withstand being installed directly into systems at 300psi maximum pressure.

EE35 Series
Dew Point Measurements down to -60°C Td (-76°F Td)
Exact dewpoint monitoring is increasingly playing a more important role in many industrial applications, such as drying processes and air pressure pipelines. For these purposes the multifunctional EE35 transmitter series offers the ideal features.
The EE35 Series is based on a functional, user-friendly housing concept and on the proven
polymer humidity sensors of the HC Series.
A specially developed autocalibration process enables measurements in a measurement range
of -60...+60 degC Td with a Td measurement accuracy of ±2 degC.
Two freely configurable and scaleable analogue outputs are available for the two measurement values (Td, T).
An optional hygrostat output, which can be set by means of a potentiometer, provides an alarm signal in a simple way when a threshold of the permitted dewpoint is exceeded.
An optional display for the measure- ment values and the associated MIN/MAX values allows a quick overview of the current situation.
Measuring range: -60...60 degC Td (-76...+140°F Td) ; 0...60 degC T (32...140°F T)
Outputs: 0-5V, 0-10V, 0-20mA, 4-20mA
Accuracy: +/- 2 degC Td; +/-0.2 degC T
Supply: 24V AC/DC

The Easidew Range is a series of instruments designed to measure dew-point and moisture content. Easidew is the most affordable range on the market but uses the newest technology. The Easidew range uses ceramic sensors to give the fastest response times, resist corrosion and cope with sudden pressure change.
The Easidew Transmitter is a two-wire loop powered dew-point transmitter designed to make dew-point measurement as easy as possible. The transmitter is fully configured and calibrated so it can be combined with any air or gas management and control system.
The Easidew On- Line is a cost effective hygrometer with digital display, analogue and digital outputs and a dual alarm feature. The Easidew On-Line is reliable and offers excellent repeatability. The Easidew On-Line can be bench or panel mounted for use in any application.
The Easidew Sampler is a general sampling system which, when used with instruments from the Easidew range, provides measurement of dew-point in compressed air and industrial gas applications. The Sampler allows a sample of gas under test to be conditioned for measurement at atmospheric or full-time pressure. The Easidew Sampler provides flow and pressure regulation and an in-line particulate filter, housing the sensor all in a single monolithic block assembly. The system can be mounted on a panel, post, or pipe brace.
The Easidew TX I.S. and Pro I.S. are both dew-point transmitters designed for use in hazardous areas. Both are certified by ATEX and thoroughly protected to avoid damage in hazardous conditions.

Optidew is based on the fundamental chilled mirror principle for dew point measurement. It offers a measurement range of <0.5% to 100% relative humidity at operating temperatures from -20°C to +90°C (however this range is extendable up to 130°C with a higher integrity sensor head). The Optidew transmitter can be used in many industrial environments. Optidew offers two linear 4-20mA outputs allowing configuration and monitoring by a suitable computer, PLC system. Michell Instruments also provides its own monitoring and configuration software with logging capability available via RS232 communication. An adjustable volt-free contact alarm is also available for direct process control. An optional high definition alphanumeric display provides local indication of the measured humidity.
Comprehensive user software makes it easy to set instrument parameters such as measurement units (RH, temperature, dew-point, g/kg and g/m3), output range, °C or °F operation etc. The software also provides a data logging and live charting facility and a min/max/average calculation.
The Optidew is available in single or two stage sensor variants according to the measurement range requirement with integrated or remote type sensors. Two display options can also be specified, providing a simple 3.5 digit LED display or a back-lit LED display.

The HygroFlex series is ideal for all applications where exact measurement of humidity and temperature is of decisive importance, e.g. the food and pharmaceutical industries, printing and paper industries, meteorology, agricultural sector, archaeology, climatology, etc. There is hardly a field today in which these parameters may be ignored. It is ultimately the measuring task on hand that defines the instrument that best covers your needs.
The HygroFlex5 series offers you ultimate performance and flexibility thanks to its interchangeable HygroClip2 probes. The transmitters come in wall and duct mount versions. Many useful functions can be accessed with optional HW4 software.
HF5-Series is available with analog and digital outputs, so compatibilty with almost any monitoring or control system is assured. Digital versions may be networked togther to form a dedicated environmental monitoring system using HW4 software.
The new generation device not only has a unique calibration and adjustment process, but also allows probes to be interchanged in just a few seconds. This easy interchangeability during operation reduces down-time and service costs to a huge extent. The possibility of using every probe as a simulator with fixed output values is a big advantage for system validation. In the case of networked devices this can even be carried out online from a remote PC workstation.
Applications
High specification HVAC applications, building management systems, museums, libraries, environmental monitoring systems.

Hygromaster
Versatile hygrometer that measures humidity, air temperature and dewpoint
The Protimeter HygroMaster is an easy to use hygrometer with built in data logging capability. The HygroMaster is a hand-held instrument for taking spot measurements and for logging humidity and temperature values. Quick measurements of relative humidity, dew point, mixing ratio (grains per pound/parts per million by weight) and ambient temperature are shown on a split display at the touch of a button. Surface temperature measurements can also be measured with an optional surface temperature sensor, making this instrument especially suitable for condensation risk assessment and diagnosis.
