The PMA-2008 Pocket Mining Anemometer is the second generation of our battery-powered electronic anemometer for use in underground mining. Still small enough to fit into a shirt pocket, the PMA-2008 anemometer makes taking ventilation readings even easier than before!

Battery powered and small enough to fit into a shirt pocket, the Pocket Mining Anemometer is specifically designed for use in underground mining and is certified as intrinsically safe by MSHA*.  The new PMA-2008 anemometer adds an audible signal, to indicate when the 60 second count has started and ends.  Also, the LCD can now be programmed to display in metric.

Rubber covered push-buttons select between (a) 60-second Counting mode and (b) Feet-per-minute mode.

Watch where you are walking, instead of staring at your wristwatch.  With the push of a button, the PMA-2008 Pocket Mining Anemometer automatically takes a 60 second reading.  It can also be stopped for partial readings of feet-of-air.  An audible alarm informs you when the count starts, stops and at 15-second intervals.

Designed for the rigors of a mining environment, the pocket anemometer is so well sealed, it can be submerged in water.  If dropped into a puddle or sump, it floats.
No adjustments or calibration are required.  After approximately 100 hours of use, the impeller assembly easily slides out for replacement.  This is all that is required to ensure precise readings with the Pocket Anemometer.
Feet per minute mode allows for immediate checks of airspeeds behind line curtains, on long wall faces, over conveyor belts, or anywhere air flow must be verified.
Every PMA-2008 Pocket Mining Anemometer comes with its own storage case and braided lanyard. A padded nylon carrying case with room for a replacement battery and impeller is an available option.  Free up some space on your tool belt and put your old anemometer and leather pouch in the mining museum!

Finally, there is an easier way to take air flow readings in underground mines. The result of years of research and development, the patented PMA-2008 Pocket Mining Anemometer is small and lightweight, yet rugged and water resistant, able to withstand the harshest mining environments.

(a) In 60-Second Counting mode, simply walk the PMA-2008 anemometer across the entry; automatically stops counting after 60 seconds. (b) For quick spot checks, Feet per minute mode provides a moving 3-second average of airspeeds in feet per minute.

Units: 60-Second Counting mode – feet (ft), meters (m) Feet-per-minute mode – feet per minute (fpm), meters per second (m/s).

Minimum/Maximum Speed: 60 fpm (0.4 m/s), 9999 fpm (9999 m/s)

Sealing: electronics enclosure IP67, water resistant to 3ft.[1m] Floats.
Shock: drop tested to 6ft.[2m]
Battery: user-replaceable CR2032 coin cell; typical life: 300 hours
Display: reflective 4-digit LCD; digit height=0.36in. [10mm]

PMA-2008 Pocket Mining Anemometer with case (included)

Dimensions: 4.8 x 1.7 x 0.7 in. [122 x 42 x 18 mm]; case 4.8 x 1.9 x 1.1 in. [122 x 48 x 28 mm]; lanyard 10in. [0.5m]

The Lite 2 is a cordless MSHA Approved Miner’s Cap Lamp featuring a compact, lightweight design. A rotating clip makes it convenient to set the beam at any angle. The Lite 2 features advanced LED technology and high capacity Li-ion battery to generate higher output with extended use time. With a long lifespan of more than 30,000 hours, the battery can be charged for more than 1200 cycles.

The light weight and ideal center of gravity provide a secure mount, and there is no cord to snag when mounted on a hard hat. The rotating clip adjusts 45 degrees to meet different lighting requirements.

The Lite 2 has a normal working time of 13 hours with no change in brightness over the use period. The reflector reduces light absorption and greatly improves the brightness.

The rugged polycarbonate housing results in excellent impact resistance and water resistance to 15 meters. All metal parts are of stainless steel to hold up in harshest mining conditions.

Bramall Laser Systems have been in use throughout the world for over 20 years, streamlining applications as small as drainage sewers up to the massive, multi-national Channel Tunnel project, where Bramall Lasers guided the driveage toward Europe. The self-contained, battery operated Mk7 laser puts industry leading mining and tunneling accuracy at your fingertips in a portable, easy to use device.

Our rugged Mk7 laser stands up to harsh daily use in a mining environment because that’s what it was designed to do. Tested as intrinsically safe by MSHA and enclosed in an incredibly sturdy stainless steel package, our Mk7 laser will serve you for years without any regular maintenance outside of changing batteries. Mounting is as simple as hanging the laser by its integral stainless steel hooks on a cord between two roof spads.

For longer range when an intrinsically safe laser is not required, we offer our Mk7L Long Range laser. Used with our High Precision XY Mount, the aluminum bodied Mk7L offers an accurate, continuous heading for up to 1400’. Power is supplied by a separate 12VDC source, battery or line supplied.

Not all driveages are straight. For these situations, we offer our Precision Beam Deflectors, a pair of high quality matched optical prisms used to accurately redirect a beam up to 15 degrees. The orientation of the prisms allows the deflected beam to be set to a specific chord for a curve in a tunnel, saving time.

While the included spad hooks on our Mk7 laser provide suitable accuracy for most applications, our XY Mount offers greater precision with coarse and fine adjustment. Available with a 20mm pin for use with a tribrach or our fixing plate, or with a threaded 20mm rod for mounting to arch supports and other user-fabricated brackets. Also recommended for all projects using our Mk7L Long Range laser, which does not include spad hooks.

Standard Mk7

Mk7L for Long Range

The Mk7 Laser assures extremely straight mining and increases efficiency of the section crew, eliminating the necessity of running up sites. Powered by standard C cell batteries, it offers excellent straight line reference for:

Longwalls – improve head and tailgate alignment
Continuous Miners – provides constant reference
Conveyors – for accurate installations
