Programmable Alarm Relays
The two optional alarm relays can be independently programmed to switch at any dew point with variable hysteresis, which makes the transmitter ideally suited as an energy saving controller for desiccant dryers in “dew point demand” mode or safety cutoff in process control, high power laser, etc. The status of the relays is shown on the display with flashing “HI” or “LO” indicators while displaying the dew point.
User Friendly Interface
The dew point meter is operated through a menu driven user interface consisting of a custom LCD display with backlight, and four push buttons. The push buttons can be used to display several different engineering units which can be dew point in ºC, ºF, ppmv, g H2O/M3, lbs H2O/million scf.
SpanCheck™ in the Field
This field calibration procedure is fully automated, and the user is prompted through a simple one-minute procedure, which requires no additional equipment.
The HTF™ aluminum oxide sensor is the product of years of intensive research and has been thoroughly field proven and performs better than other aluminum oxide moisture sensors on the market. HTF aluminum oxide sensors are manufactured with high uniformity. Consequently, sensors are freely interchangeable without factory calibration or changing of EPROMS, as is required with conventional aluminum oxide sensors.
