Pressure meters
Using measurement technology developed from the 2000
Series the PM range offers good performance at an affordable
price.
Specifically designed for engineers using twin tube
connections, the PM range is ideal for soundness testing and
setting up boiler differential gas pressures. Manufactured from
tough ABS plastic, this water-resistant instrument is supplied
with a rubber boot to provide added protection during routine
use. It can be magnetically attached for ease of use, and the
back lit LCD allows easy viewing of the display in poor light
conditions.
The PM series is a suitable replacement for the conventional U-
tube, having a fast response coupled with high accuracy and at
low cost.
Instruments are available with alternative pressure
measurement units as factory set options or as a selectable
option on the PM-80 which also incorporates a smoothing
function.
Specifically developed to meet the performance
and cost demands of today’s HVAC professional
