Relative humidity readings are to ±2% RH from 20% RH to 70% RH.\u003c\/p\u003e\u003cp\u003eAll DewK sensors come with accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEthernet and wireless capability\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWith its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using Log Ware III client-server software. Ethernet also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you’re away.\u003c\/p\u003e\u003cp\u003eCables running along the floor can be a safety hazard, and cables hanging from the ceiling and walls are an eyesore. With the DewK, simply connect your computer through an RF modem up to 100 ft away, without the clutter of all the extra cables.\u003c\/p\u003e\u003cp\u003eIf you need a printout, send data to a printer through the RS-232 interface in real time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMath and statistical functions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIn addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity. Min, max, and a variety of other statistics are also calculated and can be shown on-screen. Daily summary statistics, including min, max, and maximum rates of change are stored for the most recent sixty days.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCalibrated sensors\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWith inputs for two sensors, each measuring both temperature and relative humidity, one DewK can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK.\u003c\/p\u003e\u003cp\u003eEach sensor is calibrated for both temperature and humidity by Fluke Calibration. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different DewKs, and the recalibration of sensors doesn’t require an accompanying DewK.\u003c\/p\u003e\u003cp\u003eSensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available directly from your local Fluke Calibration sales representative, or directly from Fluke Calibration. Spare sensors may also be purchased from Fluke Calibration as a kit, which includes a case for the sensor, a wall mounting bracket, and a 25-foot extension cable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMemory\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe DewK has enough on-board memory to store up to 400,000 date- and times stamped data points.

Alarms can be both visual (flashing display) and audible (beeping). Likewise, alarm settings can be set up and events triggered in Log Ware III. The DewK is also equipped with a 0 to 12 volt alarm output that can trigger a process control system.\u003c\/p\u003e\u003cp\u003eA backup battery shuts down the DewK’s display but maintains measurements for up to 16 hours in the event of a power failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLarge, easy-to-read display\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWant to view data from across the room?
