Most heating engineers have an electronic manometer in their tool kit and find them quick and easy to use. Instruments that display readings to ±0.01 mbar (±1 Pa) have been suitable but this is no longer true.

Modern high efficiency boilers have an air/gas ratio valve which must be set at a very low differential pressure, typically between 0.00 and -0.05 mbar. The pressure also pulses making it impossible to measure using a standard electronic manometer.

The new KANE3100-1 micro-manometer solves these problems. At low pressures it can be read to ±0.001 mbar and is accurate to ±0.005 mbar, significantly better than any standard manometer. It also includes a smoothing mode which helps damp out the pulsing. These features enable it to accurately measure flue draught as well.

The KANE3100-1 is temperature compensated which minimises “drift” when say taken from a cold van into a warm home. This ensures good stability of readings, particularly important when performing its automatic “tightness test” sequence. Up to 250 tests can be stored in the memory.

Live or stored tests including the “tightness test” can be printed via an optional infrared printer.

Other details include:

• Nominal range ± 80mbar, (Sensor protected to ± 400mbar);
• Switchable between high and low resolution;
• Switchable between: mbar, Pa, hPa, kPa, mmHg, mmH₂O, inH₂O and PSI;
• Auto and manual zeroing;
• Data hold and max/min recording;
• Printouts include date/time and user details;
• Supplied with 1m of tubing, protective pouch, battery and instructions;
• KMIRP optional printer.
