Tuning Fork, High-Quality, Set of 8

Chromium plated steel (specially meant for vibration), plain shank, with frequencies marked. Conical pointed end for accurate and complete transfer of vibration to the experiment base. The frequencies are electronically tested. Packed in set of 8. One each of C-256, D-288, E-320, F-341.3, G-384, A-426.6, B-480, C-512. NOTE: Steel Tuning Forks are better than Aluminum Tuning Forks, because they Vibrate longer due to their heavier mass, thereby helping in experiment time.

Home Weather Station
The weather forecast was made yesterday - now here comes Wiz Kid. Elegant design, innovative sensor technology, and the weather forecast presented by Wiz Kid the weatherman - these are just a few of the features of the new radio weather station.

The attractively designed weather station can be completely set up and ready to use in just minutes. It displays not only the weather data but also calculates the weather forecast for your immediate area and registers wind speeds as well as rainfall. It also provides you with other interesting information, such as the current phase of the moon, sunrise and sunset times, weather trends, room climate and more.

To find out quickly what the weather is going to be like, all you have to do is take a look at what kind of clothes Wiz Kid is wearing. Whether swim suit or scarf and umbrella, the Wiz Kid has over 50 variations for dressing appropriately for the weather just outside your door. As soon as it begins to rain and the sensor detects it, the Wiz Kid informs you by appearing with an opened umbrella - you don't even have to look outside to know. The large well-organised LCD, super flat and housed in the elegant silver-blue base station, shows you all of the important weather data in graphic and numeric formats when in normal mode. Other functions are easily accessed using only five buttons.

Greatly contributing to the accuracy of the weather data is the new E9301 radio combi-sensor. It is fitted onto a mast that can be placed in the ground and works similarly to professional devices used in industrial applications. For example the outdoor temperature is measured in the same way as professional meteorologists: 6 feet above ground and shielded from sunlight.

In addition, the combi-sensor can be set up any place up to a distance of 300 ft. from the base station without having to lay cables or drill holes. Up to 8 additional locations can be used to place the E9305 sensors to measure the temperature and relative humidity and have the data sent wirelessly via radio to the weather station using low disturbance 433 MHz technology.

  • Radio transmission: 433 MHz radio transmission linking all sensors
  • Temperature: Up to 9 sensors can be connected, two temperature values are shown concurrently, 1 indoor and 1 selectable outdoor temperature, resolution 0.18 °F, accuracy ±1.8 °F; display unit: T, dew point (indoors) and windchill display (indoors/outdoors), comfort zone indicator for indoor display
  • Relative humidity: Up to 9 sensors can be connected, two humidity values are shown concurrently, resolution 1%, accuracy ±5 %
  • Air pressure trend: Display using five arrows (rising, rising steeply, dropping, steeply dropping, no change)
  • Air pressure history: Display using bar chart, up to 24-hour tracking
  • Rainfall: Range 0 to 999 mm, display total since last reset, last 24 hrs. or 1 hr., display in mm, l/m2, resolution < 0.3 mm
  • Wind speed: Display selectable as km/hr., m/hr. or m/s, resolution 0.06 m/hr., wind sock icon for light, moderate and strong wind
  • Sunrise and sunset: Selectable display of individual locations
  • Moon phase: Display of the current moon phase in four stages
  • Time & date: Quartz clock
  • Weather forecast: With weather icons: sunny, fair, cloudy, rainy, and Wiz Kid's choice of clothing
  • Extensive memory options: Min./max. values with time & date
  • Independent of house curent: Base station, 4x AA batteries;
  • Battery operated: (2 x AA) for use in dark and low-light locations
  • Temperature: Measurement range: -4 to +176 °F Resolution: 0.18 °F - Accuracy: ±1.8 °F
  • Humidity: Range: 20.0 to 99.9 % RH, Resolution: 0.1 % RH, Accuracy: ±8 %

Magnetic Field Distortion, Sunspots & Tremor Detector
Simple electronic circuit developed by our tech staff has multiple application off sun spot activity to earthquake and micro tremors equivalent of tapping your finger on a near by rock. Also detect changing magnetic fields into the difference of less than 10e-6 gauss!!


Detects Mysterious Phenomena Not Of This World.....


Head




Control Box

See the earth's magnetic field distort under the influence of solar activity. Detects moving metallic objects such as UFOs? Predicts earthquakes, power outages, communication black outs and other weird phenomena.

When used with the included biasing magnet, the device is sensitive enough to detect tapping a finger on a nearby rock!

Detect the presence of hover craft and other potential magnetic producing disturbances. This is a powerful R&D tool for studies in these fields and can be an award-winning science project.

Battery operated two part device consists of remote sense head with built in nanoamp preamplifier. Control box contains output jacks for X & Y recorder, signal meter, audible alarm and all programming controls.

Permanent installation where the weather-resistant head may be mounted on a sturdy pole away from anything electrical or large amounts of iron, preferably in a quiet place out of the wind. A shielded cable can now be run to the control box.

Permanent installations are suggested for:
   Sunspot monitoring for possible magnetic storms
   "Unidentified flying objects"
   Warning of pending earthquakes or explosive events
   Vibration detection, etc.

Temporary installations can be made by placing the head on a sturdy video tripod and placing the control box in any convenient location. This method is preferred in the evaluation of paranormal and "the unexplained" target areas.

Specifications and controls
   Zero set control pot
   Meter and overall sensitivity control pot
   Alarm threshold and deactivation control pot
   Jack for external XY recorder
   Jack for connecting cable from "detecting head" section
   Requires 2 AA batteries for head section which last indefinitely, and 8 for control box which last for months (not included)
   Dimensions of Head: 3.5" diameter x 8" long / Control box: 7.5 x 3.25 x 5.25"
