Handheld air particle counter CJ-HLC100A

Handheld air particle counter Model: CJ-HLC100A instrument Information: CJ-HLC100A handheld airborne particle counter for clean environment instrument measuring the number of particles per unit volume of dust and particle size distribution. The basic principle is to detect the laser scattering by dust particles after the photosensitive elements of the optical sensor receives and generates a pulse signal, the pulse signal is outputted and amplified, and then digital signal processing, and standard particle signal by comparing the results of the comparison of different The arguments represented. Instrument measurement parameter settings, measurement results showed that key, timing, printing, time, date, data storage, such as by the built-in microcomputer (MCU) control and implementation of the instrument can display temperature and humidity environment and laser particle sensor monitoring report working condition. The particle counter in accordance with the international standard design (air sampling flow rate of 2.83 l / min), can simultaneously set six size range for testing, sampling time can be set according to user needs, the longest 59 minutes 59 seconds . Sampling data can be stored in the built-in flash memory, and can be downloaded via USB. The instrument further innovation in the introduction of American technology, has high accuracy, stable performance, strong function, small size, simple operation, meet or exceed the performance of similar products. Characteristics of the date and time display USB high-speed communication interface can be used to obtain data and computer communications, analysis, software upgrades and other RJ-45 remote control communication interface, which is used to obtain data and computer communications, analysis and remote operation COM built-in serial printer Interface: serial printer connected to the count limit alarm: The instrument can be set to four (ten), five (one hundred), 6 (one thousand), 7 (ten thousand), eight (one hundred thousand), 9 level (one million) of six levels count limit alarm data memory, can store 255 set of measurements whole Chinese interface, easy operation built-in sensor can measure temperature, humidity and record storage delay operations specially set backlight automatically shut down more print mode (single packet range) Technical Specifications: Test particle size: particle size is used: 0.3μm, 0.5μm, 0.7μm, 1.0μm, 3.0μm, 5.0μm; test range: 10 ~ 300,000; repeatability : relative standard deviation ≤ ± 10%; particle size Accuracy: relative error ≤ ± 10%; Source: The laser diode as a light source of the sensor; flow rate: 2.83 l / min (0.1cfm) (error ≤ ± 5%); Maximum Sampling time: 59 minutes and 59 seconds; the net time: ≤10min; count mode: Cumulative counting mode, differential counting mode, the concentration count mode; Display: LCD 240 × 160, Chinese interface, easy to operate; Power: Ni-MH batteries ( 6.0V / 3300mAH) or AC adapter (Input: 180 ~ 240V, Output: 9V / 1000mA); Battery life: Continuous testing time is about 4 hours (Ni-MH batteries); automatic shutdown; Weight: about 750g (including battery ); Working temperature: 5 ~ 45 ℃ Relative humidity: ≤90%; Standard accessories: AC adapter, self-cleaning filter, isokinetic sampling head, suitcases; optional: tripod, printer (with cable), external temperature Humidity Sensor
