The PMA-2008 makes taking ventilation readings even easier than before!
Enhancements make the PMA-2008 Anemometer better … Audible signal lets you know when the 60-second count has started, counting and ends. The LCD display can be programmed to read in metric mode in seconds.

|Mk7 ALIGNMENT LASER
Our Mk7 Lasers have been specifically designed for the demanding conditions
that exist in tunnels, mines, and drifts. We offer three models with usable ranges
of 750-1500', including two MSHA-approved Type S models. Optional
accessories, such as our XY Mount and Fan Lens, fit the Mk7 to most projects.
Pre-aligned spad hooks, single switch and battery power make
our Mk7s portable and easy to use.
|PMA-2008 POCKET MINING ANEMOMETER
The PMA-2008 Pocket Mining Anemometer is a battery-operated, electronic anemometer small enough to fit into a shirt pocket. Dustproof and waterproof, it can provide quick readings of airflow up to 9999 FPM or 9999 M/S in its metric mode. No adjustments or calibrations required. Each PMA-2008 Anemometer comes with its own storage case and braided lanyard. The PMA-2008 Anemometer is second version of our anemometer that has become the standard for taking airflow readings in gassy environments. The device is approved as intrinsically safe by MSHA for use in gassy atmospheres.
|LITE TRACKER & M-R-A DEVICES FOR SAFETY
The M-R-A MINE RESCUE ALARM is the smallest, lightest and loudest rescue alarm available. Manually activate or use the motion function to automatically alert to inactivity.
The LITE TRACKER offers continuous, flashing or strobing lights for instant recognition of the wearer. Different colors allow for distinctive coding for personnel or underground features such as man doors and emergency caches. Both are MSHA approved as intrinsically safe for use in gassy atmospheres.
MPS Talentum sensors provide fast response to spark or flame, while rejecting radiation from warm objects. The use of proprietary photocells and sophisticated processing allows for accurate, reliable detection in various conditions, and results in a high tolerance to dust and condensation. Utilizing IR, UV, or a suitable combination, sensors are available for a wide range of applications.
|PRECISION BEAM DEFLECTOR
Our Precision Beam Deflectors are used to redirect the beam of any laser when guiding in a curved tunnel drive, decreasing the necessity of laser movements. They utilize a pair of high quality, matched optical prisms to control a laser beam deflection. The Beam Deflector will deflect the beam up to a maximum of 15 degrees to a new chord point on the tunnel curve.
