Bơm lấy mẫy khí/ bụi IAQ, 5 – 15 LPM

Flow Range

5 to 15 L/min

Flow Control System

Closed loop with patented internal flow sensor
U.S. Patent No. 5,892,160

Compensation Range

15 L/min at 5 inches water back pressure
10 L/min at 12 inches water back pressure
5 L/min at 20 inches water back pressure

Accuracy

Flow rate: ± 5% of set-point after calibration to desired flow
Timing: 1 min/mo at 25 C
Atmospheric Pressure: ± 0.3 in Hg

Flow Fault

If the pump is unable to compensate for > 15 seconds due to excessive back pressure, a flow fault icon displays and flashes, the pump enters Hold mode, and the pump retains historical data. Auto restart is attempted every 20 seconds up to 10 times. Adjustable with DataTrac for Leland Legacy software

Flow Control

An internal isothermal flow sensor measures flow directly and continuously. Sensor readings are used in a flow monitoring algorithm to maintain calibrated volumetric flow. In addition, built-in atmospheric temperature and pressure sensors provide readings to correct volumetric flow for these parameters when they vary from point of calibration.

Tubing

Requires 3/8-inch ID tubing

Display

LCD, displays pump serial number, pump software revision level, flow rate, volume, temperature, atmospheric pressure, time of day, run time, and pump status, i.e., hold and run as well as Setup information

Volume Display

Continually updated, based on corrected flow rate multiplied by sampling time. When volume exceeds 99,999 liters, the pump will continue to run normally but an O_FLO error will appear on the LCD.

Time Display

Time of day in hours and minutes (12 or 24-hour clock) with AM and PM indicators

Timer Display Range

1 to 99999 minutes (69 days). If the run time exceeds 69 days, the timer display rolls over.

Operating Temperature Range

32 to 113 F (0 to 45 C)
Protect sample pump from weather when in use outdoors.

Altitude

The pump can apply correction to volumetric flow during sampling for weather-related or altitude variations from the atmospheric pressure established at calibration up to at least 7500 feet above and 5000 feet below sea level.

Typical Run Time^†

24+ hours:

• Sioutas Impactor at 9 L/min (approximately 13 inches water back pressure)
• Personal Environmental Monitor (PEM) with 37-mm, 2.0-µm PTFE filter Cat. No. 225-1709^‡ at 10 L/min
• Low-volume PUF Tube at 5 L/min
• DPS Sampler (PM2.5 or PM10) at 10 L/min
• For extended run times, the pump may be operated while attached to the approved charger.
• 8 L/min Respirable PPI

Noise Level

62.5 dBA — pump without case
52 dBA — pump housed in noise-reducing case (optional accessory Cat. No. 224-89)measured 3 ft (1 m) from pump operating at 10 L/min without media

User-adjustable Values

Sample run time, calibration, clock display, flow rate, time of day, delayed start, and temperature and atmospheric pressure display

Recorded Values

Start date and time, stop date and time, total sample time, flow rate, sample volume, temperature, atmospheric pressure, and pump mode transitions

Adjustable LoggingInterval

Records pump history from 3 seconds (15.4 min of data) up to 8 hours (over 102 days of data) depending on setting. Option available when using DataTrac Software
