Apex Personal Sampling Pumps

The Apex personal sampling pumps are available with flow ranges from 0.8 to 5 L/min. Intrinsically safe (IS) models available with flow ranges from 0.8 to 4 L/min. Low flow adapter for flow ranges of 5 to 800 ml/min. The LCD displays the flow rate, volume sampled, elapsed sample time, ambient temperature, and current operating mode. NiMH battery provides up to 34 hours life, with a drop-in fast charger for recharging in less than 3 hours. Optional replacement alkaline battery pack for emergencies. Infra-red wireless computer communication with the Pro models.

Apex pumps are compatible with commonly used sampling devices such as filters, sorbent tubes and cyclones.  Sampling accessories available from Casella include a conical inhalable sampler, an Institute of Occupational Medicine sampler, a total inhalable sampler, an asbestos sampler, a respirable cyclone and a rosin/solder fume sampler. Various sized polyurethane foam filters are also available.

Apex Lite Non-IS Personal Sampling Pumps

The Casella Apex Lite personal sampling pumps are low cost starter pumps with thicker windows to minimize accidental damage to the display. The pumps have flow rates from 800 to 5000 ml/min and 5 to 750 ml/min using a low flow adapter. Apex Lite pumps are available in standard and programmale versions and have up to 45 hour run times at 2 L/min with a 25 mm GFA filter. This represents a full week of full day sampling from the same set of batteries. The pumps are supplied with a one time alkaline battery pack for infrequent use, which can be easily upgraded to NiMH rechargeable batteries.

Microdust Pro Particulate Monitor

The Microdust Pro is a portable, real time monitor for assessing the concentration of suspended particulate matter over a wide dynamic range from 1µg/m3 to 2500 mg/m3.. The Microdust Pro can be set to analyze total suspended particulates, PM10, or PM2.5. The logging interval can be set from 2 seconds to 10 minutes, and the memory can datalog >15,700 data points. It is the only hand­held real-time dust monitor capable of graphically presenting variations in dust concentration on a real time scrolling graph – no longer is it necessary to wait to analyze results on a PC.

Nomad Portable Weather Station

Nomad portable datalogging weather station can monitor and log wind direction, speed, barometric pressure, temperature, relative humidity, dew point, rainfall and solarimeter data. It is suitable for all types of emergency, hazmat, biological release, security response and environmental monitoring. An integrated solar panel charger allows extended operation. Telemetry options include remote operation and data collection via wireless or modem communication. Supports up to four additional sensors such as soil temperature, leaf wetness, grass temperature, SOX and NOX.

The WBGT real-time heat stress meter measures and datalogs wet bulb, dry bulb and globe temperatures simultaneously from three PRTD sensors.  The meter automatically calculates the heat stress level in the work environment using the Wet Bulb Globe Temperature  Index and logs that value for both indoor and outdoor work environments. 

Both the meter and the sensor unit have tripod sockets for ease of use.  The sensors can be mounted directly onto the body of the instrument or remotely positioned using a 30 ft cable.. The WBGT has built-in audible & visual alarms for RH%, dewpoint and wet bulb reservoir water levels.
