Description

Description:
High Volume Samplers are the basic instruments used for monitoring dust in Ambient Air. They are in widespread use all over the world. In these samplers, airborne suspended particulate (SPM) are measured by passing air at a high flow rate through a high-efficiency filter paper which retains the particles and provisions have been made for simultaneous sampling of gaseous pollutants also.
It has a continuous duty blower with a brushless motor to ensure continuous working for up to 28 hours. The noise level has also been reduced by using a noiseless blower. It also has provision for gaseous sampling for example NOx It is more compact and lighter can be carried in a car trunk and is ideal for field use.
Features:
Unique flow measurement system using an orifice plate directly calibrated in cu m/minute 
Anodized aluminum body & framework to support various parts of Sampler to withstand weathering effects
Separation of gable roof from the main housing, making the system more rugged & compact for easy transportation
24 hr programmable timer
Reduced noise
Less variation in flow
Silicone tubing in place of PVC tubing
Lighting facility to facilitate monitoring in the absence of ambient light

Specification:

Flow Rate: 1.1to 1.7 Cu m/min (Free Flow)
Particle Size: Down to 0.5 micron depending upon Filter used
Recommended filter: GFA (8” x 10” ) for common use
Sampling Time Record: 0 to 99999.99 hrs. Time totalizer records the running time in hours
Sampling Time: 24 hour programmable timer, required intervals can be conveniently programmed
Power requirement: 220 Volts, 2 Amps, Single phase AC
