Optica Hygrometer
The Optica Hygrometer offers precision dew point measurement. Precisely controlled by GE's chilled mirror sensing technology - providing NIST traceable humidity,temperature and pressure measurement anywhere via the worldwide intranet.
The Optica Hygrometer measures dew point temperature by regulating the temperature of a polished metal mirror by the use of optical feedback such that a constant mass of dew or frost is maintained. The temperature of the mirror is measured with a precise PRTD and is by definition equal to the dew or frost point.
Features & Benefits:
Simultaneously measure and display dew point, temperature, and pressure
Display any humidity parameter
Ethernet ready, so you can access GE Optica hygrometers via the Internet for remote monitoring applications
Data logger function lets you record & upload weeks of data
Primary NIST Traceable Humidity Transfer Standard
Accuracy to +/- 0.15C

Overview
The model DP-19 is a robust, easy to carry dew point hygrometer, specially designed for field use.
Typical Application
A typical application of this instrument is the spot measurement in sulphur hexafluoride (SF6). Measurements are made at pressures between 10 mbar and 10 bar (1 kPa to 1 Mpa). Sample gas flow is effected by pressure difference between gas inlet and outlet, with a minimum of 10 mbar (1 kPa). If sample gas pressure is too low or the gas has to be measured in a closed circuit, an optional gas pump is available.

The MDM300 is a high-speed dew point portable hygrometer which uses Michells ceramic impedance sensor and state-of-the-art thin and thick film techniques. Operation of the sensor depends upon the adsorption of water vapour into a porous, non-conducting sandwich between two conductive layers built on top of a base ceramic substrate. The MDM300 provides the fastest spot check measurement of dew point or moisture content in a small portable instrument and is packed with features and intelligent engineering.
The user-friendly MDM300 offers an extremely fast response speed and an accurate and stable measurement. The hygrometer has data-logging and built in sampling components as standard and a range of optional accessories are available such as a stand-alone sampling system and a professional carry case.
The MDM300 uses the latest Bluetooth wireless technology to offer a quick and easy assembly and downloading process. With a choice of four different sampling arrangements (from fixed orifices for low pressure to high quality configurable sampling systems for high pressure), the MDM300 offers a cost effective and easily portable service to the user. The MDM300 is able to connect to external sensors to measure dew-point, temperature and pressure and also to re-calibrate other Michell Instruments such as the Easidew Transmitter. The original design and long battery life makes a perfect hygrometer for laboratory or portable use.

Q & A:
A room has an ambient room air temp of 70 Deg F, followed by a brief period at 50 Deg F for 5 seconds, then returning back to 70 Deg F again. Will the meter be able detect this temperature change and display it as a minimum reading ?.
I did an experiment on DTM-550 at the out flow gate of air conditioner from room
temperature of 78.8 deg F( 26 deg C).
The reading 59 deg F ( 15 deg C) takes 5 seconds.
The reading 50 deg F should take around 10 seconds.
There is no minimum reading button for DTM-550 but you can have " Hold" function
to read what you measure.
Please note this unit is not available for Fahrenheit display and only for Celsius.

HI 9564 and HI 9565 are two new portable thermo-hydrometers designed to provide excellent performance in harsh environments and poorly lit areas.
A microchip built into the RH probe, HI 70602, can store calibration data. When the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument.
Both instruments feature auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and on-line help to indicate anomalies and direct procedures.
In addition to RH and temperature, HI 9565 will display the dew point with the press of a button. The dew point indicates the presence of water vapor in the air at a given temperature. With this feature HI 9565 permits useful and rapid environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms and laboratories.
