The accuracy of weather instruments we offer varies from very basic up to scientifically accepted. Generally the level of accuracy is reflected in the price. Bear in mind that it is often trend or linearity that is more important than accuracy.

Digital consumer products often state resolution which should not be confused with accuracy. Resolution is simply the number of decimal places that the instrument can display and not its accuracy. Consider also a traditional bulb thermometer where the accuracy depends on the scale being correct and aligned correctly as well as your ability to read off the mensicus against that scale.

For consumer products

If you are in a stone property or a building whose construction may be a barrier to wireless signals then you should consider carefully before purchasing a wireless system.

You may already be aware of problems affecting other wireless devices you have. The performance of the transmission may be affected by the density of the fabric or where you position the sensors and the receiver.

By making sure that there is a line between them without passing through difficult building fabric, such as placing the receiver in a window reveal in sight of the sensors, the signal should find a way through without a problem.

Although wireless products work well for the vast majority of users reception can be adversely affected by a host of other apparently invisible influences. Interference from other transmission rarely causes problems because it is on other frequencies but adjacent high power transmission such as mobile phone masts and power transmission lines can cause problems.

The products we sell come with a 1 year manufactures unconditional warranty. However we are always willing to look at products that might have had manufacturing faults that did not manifest themselves within that period.

By the nature of the product and fact that they have been installed outside we need to see and test any items thought to be faulty before we can offer a repair or exhange. We ask you to consider that there is not point in sending you replacements and repairs until we can be sure which if any component is faulty.

We have our own test facilities for comparing wind speed against calibrated anemometers, barometers and thermometers against known good references, rain gauges with measured amounts and even spectrum analizers for RF signals. Armed with all these tools we have a greater ability than anyone we know to diagnose and resolve problems.

Please contact us with your order number both during and after the warranty period for

A Weather Forecaster usually provides any of the following information.

• Temperature (In and Out)
• Humidity (In and Out)
• Barometric Pressure numerically and graphically
• Weather Forecast up to 24hrs ahead
• Moon Phases

You will probably be able to add extra Temperature, Humidity and UV sensors depending on the model.

A Complete Weather Station provides in addition to the above

• Wind speed and direction
• Rainfall information

Depending on the sophistication of the model you purchase you may be able to add additional sensors. Not just for temperature and humidity but also for UV (ultra violet) and solar radiation, soil moisture and temperature and leaf wetness.

Most of these complete weather station systems can be connected to a PC to log and record the data collected through a serial or usb port and even an IP connection.
