Low-E Coating Detector
DUAL PURPOSE SINGLE / DOUBLE
Low-E glass is a vital component of energy efficient windows. It has a virtually invisible surface coating which this detector is designed to detect. The coating itself works as follows: · It allows heat from the sun in the form of shortwave radiation to enter the building through the glazing. · This solar energy along with any heating system will warm up the room, this in turn gives off long wavelength heat radiation. · A large proportion of this long wave radiation would disappear through windows made of ordinary glass. However, the Low-E coating reflects this heat back into the room making it more energy efficient.
Single Sheet Glass
During manufacture it is important to know on which surface of the glass the Low-E coating is present. Simply place the two metallic sensors against the glass as shown below. Note: There is no need to press the red button as the sensors are self activated.
Position 1
When the sensors are not in contact with the low-e coating no audible tone will be heard.
When the sensors are in contact with the low-e coating an audible tone will be emitted from the detector to indicate its presence.
Double Glazed Units
To check the presence of a low-E coating in a double glazed unit simply place the tool flat onto the glass as shown below and press the red button.
Position 2
If the tool does not detect the presence of a low-e coating on the piece of glass that the tool is touching no audible tone will be emitted. If no tone is emitted simply repeat this procedure on the opposite side of the unit as shown below.
If the tool detects the presence of a low-e coating on the piece of glass that the tool is touching an audible tone will be emitted to indicate this. If you wish to check that a double glazed unit has been manufactured correctly and that the coating is correctly orientated towards the air-space simply follow the procedure to detect which piece of glass has the low-e coating as shown in figs 3&4 above. Once you have done this simply touch the two metallic sensors against the glass as shown in figs 1&2. The Coating should always be facing towards the airspace and not exposed to the outside where it can become damaged, therefore no audible tone should be heard during this part of the test.
Batteries.
This unit is fitted with a 9 Volt PP3 type battery which should be changed periodically or when the low battery indicator light below the switch becomes illuminated.
