Digital Velosity Monitor Model APM 101 Model APM-101 is designed to determine velocity of air/flue gas in duct /pipe/chimney. Where determination of the rate of flow inside a chimney is of interest. This instrument can be conveniently used to measure the total quantity/volume of emissions. Lata Envirotech Digital Velosity Monitor Model APM 101 APM–101 is designed to determine velocity of air/flue gas in duct / pipe/chimney. In situations where determination of the rate of flow inside a chimney is of interest, this instrument can be used very conveniently to measure the total quantity/volume of emissions.

Special Features :

• Hand Held Velocity Monitor & Compact
• Digital pressure cell in place of cumbersome liquid manometer
• Highly accurate & reliable readings.

Ambient air enters the APM 154 MFC Sampler through an omni directional inlet designed to provide a clear aerodynamic cut-point for particles larger than 10 microns. The air stream then passes through a WINS Impactor that retains the fraction between PM 10 and PM 2.5. The PM 10 and PM 2.5 impactors used in the APM 154 MFC are based on designs standardized by US-EPA and as such the system complies with international norms for PM 2.5 Samplers.

Special Features :

• PM 10 and PM 2.5 Impactors of sampler based on designs standardized by US EPA.
• Flow Control based on Mass Flow measurements to remove errors due to pressure, temperature changes (of both ambient air and filter).
• Auto shut off if flow rate drops significantly below 1 m3/hr.
• Microcontroller based data logger records Air Temp., Filter Temp and flow rate.
• Windows based software for downloading data.
• Pump Assembly in separate cabinet to prevent loss of volatile fraction and improve portability.
• Special imported oil free brushless vacuum pump that is practically noiseless
