Portable Six Channels Optical Dust Laser Particle Counter Air Quality Detector

Description: Portable Six Channels Optical Dust Laser Particle Counter Air Quality Detector Introduction: 1. The Model handheld optical particle counter utilizes the laser technology for single particle detection. The scattering of light from the particles in the sampling air steam is converted into electrical pulses, which is then measured and calculated as a particle size. The Model consists of a handheld setwith a main base unitthat allows users to conduct the sampling around with a handheld set while easily expanding to multiple functionalities with a base unit. These extended functions include data downloading, data real-time printing, software upgrading, and batterycharging, etc. 2. The Model has up to six adjustable particle size channels starting at 0.3 microns with a step resolution of 0.1 micron at a flow of .1 CFM(2.83 LPM). Particle countdata is displayed as Cumulative, Differential or Concentration mode(Counts/Literor Counts/Cubicfoot, Counts/Cubic Meter). The Model can also include a digital temperature and relative humidity probe, backlit interface and is capable of storing6,000 sample records. lt is in compliance with the intemational standards(JIS B9925:1997 andlS014644-1) and support both metric and English systems. Features: User configurable for six size channels Set and display date and time. High speed USB interface for data downloading Count Limit Warning: Setting according to the FED standard 209E or lS0 14644-1 standard Error status indicator: The instrument will automatically monitor the sensor status, out of flow calibration( >±5% ) , or insufficient battery Up to 1000 sets of data can be saved. Timer, auto-start sampling. Average of multiple times of measurements External temperature and humility sensors to assure accurate measurement Support both English and Chinese languages display. No less than 5 hours of continuous operation. Auto print function. Application: Ultra-clean environment testingIndoor and outdoor environmental testingAnalysis and test of filter efficiencyCheck pollution source analysisAnalysis of particle size distributionJudgment basis for environmental cleanliness level Specifications: Test particle size the user can according to the needs, according to the step size of 0.1μm between 0.3 ~ 5μm And the particle size of the six channels to be measured can be set arbitrarily in the step size of 1μm between 5~25μm Consistency loss less than 5% when 2,000,000 particles per cubic foot Light source Laser diode Flow rate 0.6 liters/minute (0.1cfm) Counting efficiency 50±10%@0.3μm 100±10%@0.5μm Verification standard JIS-B-9921(1997) ASTM-F649-01 ASTM-F328-98 (NIST traceable) JJF1190-2008 Sampling time user-defined (1 second ~ 59 minutes 59 seconds) Sampling delay user-defined (1 second ~ 59 minutes 59 seconds) Sampling frequency 1 to 99 times or continuous Alarm level 100 to 1 million (FED209E standard) or 5 to 9 (ISO14644-1 standard) Test range: 100 to 1 million (corresponding to ISO 5-9) Test method single/repeat/continuous/timing/average Data memory capacity 6000 measurement data Error indication The maximum count is exceeded, the laser power is attenuated, the calibration flow rate is exceeded (>±5%), and the battery power is insufficient Self-cleaning time ≤5min Interface USB Maximum communication rate 12Mbps Printing function Built-in high-speed thermal printer Flowmeter accuracy 2.83 l/min ± 5% Power supply: Rechargeable Li-ion lithium polymer battery (7.4V/2800mAh) or AC power supply (AC100~240V,output: DC 9V/1.5A) Battery working time Continuous test time is greater than 6 hours Dimensions 93 (W) × 48 (D) × 185 (H) mm (handheld host) F 152 × 97 (H) mm (base) Weight Host: about 600 grams (including battery) Base: about 400 grams Environmental conditions Working environment: 5~45℃, <90%RH Storage environment: -20~60℃, <90%RH Standard accessories AC adapter, zero filter, isokinetic sampling head, portable protective box, application software installation CD (including instruction manual) Optional accessories External temperature and humidity sensor
