MINING & TUNNELING
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.
SIMPLE PUSH BUTTON CONTROL
Rubber covered push-buttons select between (a) 60-second Counting mode and (b) Feet-per-minute mode.
AUTOMATIC 60 SECOND COUNTING 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.
DUSTPROOF / WATERPROOF
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 CALIBRATION
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.
QUICK SPOT CHECKS
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.
TAKE YOUR LEATHER POUCH OFF YOUR TOOL BELT
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!

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 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.

MSHA Approved
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.
Mk7L FOR LONG RANGE
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.
PRECISION BEAM DEFLECTORS
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.
XY MOUNT FOR GREATER PRECISION
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.
