Elcometer 270 using Separate, Telescopic Wand and Roller Sponge.

Automatic Voltage and Sensitivity Calibration Check: A feature of the Elcometer 270 which makes it unique and distinguishes it from any other pinhole detector available on the market today, is the internal calibration check. When the detector is switched on or after a voltage setting change, the unit runs an internal voltage and sensitivity setting calibration check. A successful check is signified audibly and visually. The detector will only function after a successful calibration check has been made, giving the User complete confidence in its performance.

Low Battery Indicator: To ensure the gauges always generate the required voltage, the Elcometer 270 is fitted with a low battery indicator which not only warns the user when the batteries need changing, but also gives them a minimum of 10 hours to change them - providing ample time to complete the work in the sure knowledge that the voltage and alarm threshold accuracies are maintained.

Visual and Audio Alarm: When the wet sponge passes over a pinhole, current flows from the detector through the moisture in the hole to the substrate below and back to the detector via the signal return lead. This current flow triggers an audible and visual alarm.

Integral and Separate Wand Functionality: Each model can be simply and quickly transformed from an integral version into a separate wand version (with a belt clip for the detector). When purchasing a separate wand accessory (T27016999 or T27016998), the belt clip is provided free of charge

4 Model Variants: Having recognised the fact that the USA market demands 67.5V to meet the ASTM standard and customers around the world require 9V to measure thin coatings up to 300µm (12mils) and 90V to measure thicker coatings up to 500µm (20mils) to meet ISO standards, the Elcometer 270 is available in single, dual and triple voltage variants.

Easy release, snag proof cables: To avoid snapping the cables when snagged, each cable is connected to the wand or the gauge by a simple push fit connector. This cable connection releases if the cable becomes snagged.
In the unlikely event of a cable break, the bare cable can be connected to the gauge using the special terminal at the gauge.

Larger Standard Sponge: The Elcometer 270 Standard Gauge is supplied with a larger sponge than the Elcometer 204 and Elcometer 269 gauges it replaces. A larger sponge means a faster inspection time as more area can be tested in a single sweep. The larger sponge can still be used to precisely locate the pinhole by using a corner of the sponge to find the hole.

A Wide Range of Fully Interchangeable Wand Accessories: We have developed a range of accessories for the Elcometer 270 increasing the versatility of the instrument and the range of applications for which it can be used.
