Environmental Monitoring & Control Systems


The Airwolf is an Intrinsically Safe (IS) handheld Airflow meter that uses the Vortex shedding principal. It also gives the option of instantaneous as well as average airspeed (Traversing).

  • No calibration in field required
    (factory calibrated)
  • No moving parts therefore highly insensitive to dust & humidity
  • Long life battery
  • Range is 0.1-10m/s
  • Intrinsically Safe (I.S)
  • Display of average airspeed over a period (Traversing)
  • Accurate and easy to use
  • 2 Year battery life
  • IP65
  • Man portable
  • Alkaline battery


A series of economical gas sensors for Non-IS applications. Available in all gas types such as: CO, CO2 CH4, H2S, SO2, NH3

On site calibration at 6-month intervals

  • Accurately measures specific type of gas (p.p.m. readings)
  • Local alarm (105db at 30cm)
  • Robust IP65 glass filled polyester enclosure
  • Address and Alarm set point values via on-board ethernet point
  • Low power consumption
  • Visual Indication
  • Robust IP65 glass filled polyester enclosure
  • LCD display


The Can Robo is a compact, omnidirectional and robust Air Velocity measurement device for roadways.


The MultiSens accurately measures airflow, carbon monoxide (CO) and methane (CH4) and is housed in an IP65 single stainless steel enclosure.

  • Onsite calibration at 3-6-month intervals
  • Current methane (CH4) sensor can be upgraded to hydrogen sensor (H2)
  • Ambien temperature measurement allows for easy compliance to the Fatigue Management Plan set out by each individual mine

A range of single gas and airflow sensors certified to the Exia Standard which can be optionally coupled to the mines existing backbone via the 4-20mA output signal. Standalone sensors are available to measure additional gasses specified by the mine:

    • Methane (CH4)
    • Carbon Monoxide (CO)
    • Air Velocity (AV)
  • Measures Co (Carbon Monoxide), `
    CH4 (Methane), Air Velocity and
    Ambient Temperature
  • Firepatrol digital input for maintenance control
    measurements via external push button
  • The MultiSens is a compact NON-IS / Intrinsically Safe (IS) environment monitoring unit Exia Group I standards.
  • On board data communication interface
  • Local audio / visual alarm options
  • Ultrasonic Airspeed measurement is not affected by dust, water or temperature
  • The (FSS) Fail Safe Strobe is an on board visual healthy or unhealthy indicator
  • Local Audio-Visual Alarm Option
  • 2 Additional inputs are available for 2 additional gas sensors to be monitored
  • The MultiSens can be integrated into Scada/PLC networks to give a real time status indication locally and in the control room


As smoke is the primary visual indication of a fire, the SmokeSens was designed to detect smoke density effectively, using optical obscurity technology.  False alarms caused by stone dust has greatly been minimized in the latest design This information can also be sent to the surface control room for trending and alarming.  An Intrinsically Safe (I.S.) version of the SmokeSens is available.

  • No Radioactive material used in design.
  • Advanced optic technology.
  • Automated Detection and alarming of blocked filter.
  • Advanced Optical Detection technology.
  • Aspirated –Draws air into the measurement chamber.
  • Detection of smoke from synthetic conveyor belt, where CO is low and not detectable.
  • Calibration preformed with CSIR verified optic filter.
  • Integrated tracking function to compensate for drift due to environmental factors.
  • Transmissive measurement – sensitive to all colours of smoke.
  • 4 – 20 mA output for long distance data communication to PLC.
  • Local flashing alarm strobe (optional)
  • Local Audio alarm.
  • Low power consumption
  • Local display for percentage obscurity level
  • Robust enclosure
  • Removable
  • Swappable/exchanging/filter cassette for ease of maintenance underground.
  • B.I.T.E – Built in test equipment

Excellent quality and workmanship of their products. A wonderful team to work with.
