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

Model 660 Air Velocity Monitors are a practical, affordable way to continuously monitor for safe air flows through laboratory fume hoods. They are typically installed in the fume hood side fascia and connected to the interior sidewall via 1-18" flexible tubing. As the exhaust fan draws air through the device, a sensitive constant temperature thermistor measures flow and lights a green (normal), yellow (high) or red (low) LED. An audible alarm also warns of low flow and requires manual resetting. Mounting holes fit standard single gang electrical box.

Measuring system for continuous evaluation of flow velocity and flow direction in tunnels. Ultrasonic sensors for tunnel ventilation control system. Reliable measurement across the tunnel profile. Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependant on direction and calculates flow speed. D-FL 220T requires extremely low maintenance.

Testo 512 has a measuring range from 0 to 20 hPa and is ideal for measuring differential pressure at filters and for carrying out pitot static tube air flow measurements between 5 and 55 m/s in air ducts.     Features:     • 8 measurement units to choose from: psi, kPa, hPa, Pa, mm H2O, mmHg, inch H2O, inch Hg   • 2 air flow units to select from: m/s, fpm   • Integrated density compensation     • Backlit display, min/max values, hold function

We are offering digital velocity monitor 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. sle – dvm174 is provided with a digital pyrometer and thermocouple for measurement of temperature. A digital pressure cell is incorporated in a hand held unit for the measurement of pressure in mm of h2o directly along with a pitot tube. The pitot tube has been provided with an extendable arm for easy transportation. features : • compact hand held velocity monitor • digital pressure cell in place of cumbersome liquid manometer • highly accurate & reliable readings • carrying case • measures velocity as high as 100 m/s technical specifications stack temperature range: ambient to 600 ⁰ c read on a digital pyrometer. stack velocity range: 2 to 1 00 m/sec. thermocouple: thermocouple sensor in ss 304 casing, length of insertion: 0.6m with 2m long cable manometer: digital with 0-1300mm of h, o range with 0.1mm least count. pitot tube: modified calibrated s-type pitot tube fabricated from ss 304, 0.6m length with extension of 0.6m. list of components sle – dvm174 : instrument panel consisting of digital pyrometer & digital manometer, pitot tube, thermocouple, connecting pipe, carrying case etc.
