Accuracy

The standard-accuracy sensor (“S” model) reads temperature to ±0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ±2% RH from 20% RH to 70% RH.

All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.

Ethernet and wireless capability

With 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.

Cables 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.

If you need a printout, send data to a printer through the RS-232 interface in real time.

Math and statistical functions

In 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.

Calibrated sensors

With 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.

Each 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.

Sensors 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.

Memory

The DewK has enough on-board memory to store up to 400,000 date- and times stamped data points. That’s two years’ worth of data for both measurements from two sensors if readings are taken every ten minutes!

Alarms and battery backup

Alarm settings can be set up quickly in the DewK based on temperature, the rate of change in temperature, RH, the rate of change in RH, and instrument fault conditions. 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.

A backup battery shuts down the DewK’s display but maintains measurements for up to 16 hours in the event of a power failure.

Large, easy-to-read display

Want to view data from across the room? Want to view data from two temperature and two humidity inputs simultaneously? Want to view data graphically, statistically, or both? At the same time?!

The DewK does everything you could want—or at least everything we could think of. Up to sixteen different display setups can be stored and recalled at the touch of a single button. And all 16 can be easily modified, so you get exactly what you want.

If you’re surveying, installing, executing maintenance or checking performance of solar panels or a photovoltaic system, the Fluke IRR1-SOL Irradiance Meter gives you the 4 critical measurements needed all in one easy-to-use tool.

Make instantaneous measurements to determine the watt per square meter solar irradiation, required by IEC 62446-1 standard. Measure temperature by either placing the meter directly on the panel or by connecting the external probe. Find cardinal direction with the compass, and verify inclination of a roof or panel with the tilt function.

To find the expected production at a site, determine your solar resource while taking shading into account. The solar resource is measured in peak sun hours: the number of hours per day with 1,000 watts generated per square meter of solar array.

Location, time of day, season, and weather conditions all influence peak sun hours. Use the Fluke IRR1-SOL to determine the actual solar irradiance (Watts/m²) and shading at the site to develop a baseline.

Once your system is installed, make sure it is operating as designed by measuring its electrical characteristics and the actual power output of the array. The performance of a photovoltaic array is based on its current-voltage (IV) curve. Use the IRR1-SOL to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output.

Even when installed correctly, a photovoltaic system may not be producing the expected electrical output. In order to produce the expected output the system needs to receive the correct amount of irradiance energy to generate the DC voltage that is fed into the inverter.

Whether working on a roof-mounted system or on a large field installation, the IRR1-SOL is the single-handed solution that every solar installer and technician needs in their tool bag.
