LZJ-01D handheld particle counter | Zhejiang professional manufacturer | factory outlets Product: Particle Counter Model: LZJ-01D I. Overview: It adopts imported semiconductor photosensitive semiconductor laser tube and acceptable control to ensure that the sensitivity and speed of response. In order to ensure a stable flow, the company's first imported miniature pump. The core component of the light scattering instrument sensor is crystalline Our many years of hard study. The structure can significantly eliminate stray light within the cavity, the SNR obtained is greatly improved, so that more accurate and reliable measurements. Confidence measure of this instrument is that all similar products in the only two conditions in accordance with the national standard GB/T16292-194896 to automatically determine the level of purification. At present, the storage capacity of the instrument has been increased to 800 data can be freely according to the time to check past data. Also available communication interface connected to the computer. Instrument with temperature and humidity sensor interface, connected to the temperature and humidity sensor (optional) can simultaneously measure the temperature and humidity, took the lead in the domestic similar instrument with digital indication of the sampling flow rate, and thus more intuitive and more accurate. The instrument can be AC ??and DC, can easily enable internal battery (rechargeable) power supply, can be used continuously for six hours when the power cord is not up to the power outlet or power outage. The instrument is made of high quality stainless steel chassis hairline, inclined structure, blue screen, small size, light weight, novel appearance, clear display, easy to carry, long-term use, still as new. Our company specially imported American Royco particle counter calibration and measurement equipment Duk's standard particle, thus ensuring products have been rigorously measured calibration at the factory to ensure quality. Our package two years, with a customer service center in Shanghai, the user will be required prompt and friendly service. Second, the technical indicators: According JJG547-88 particle counter test procedures required. 1, self-cleaning time ≤ 15min; 2, noise ≤ 62dB (A); 3, particle size distribution repeatability ≤ ± 10% 4, the particle size distribution accuracy ≤ ± 40%; 5, monodisperse particle dispersion ≤ ± 30% 6, sampling flow 2.83L/min; three conditions: 1, the maximum concentration of dust particles 40K pcs / l 2, the surrounding normal atmospheric conditions without strong magnetic field 3, power A.C220V ± 5% 50HZ AC-DC dual-use stainless steel bevel 220 * 285 * 140mm (W * D * H) Weight: 3 .6 kg IV advanced and features: 1, imported semiconductor laser tube and imported semiconductor photodiode to ensure the sensitivity and speed of response. 2, imported miniature pump to ensure the stability of sample volume while reducing noise. 3, the core component of the instrument ----- light scatter sensor, the factory crystalline years of research, the structure of the cavity can significantly eliminate stray light noise ratio is greatly improved, so that the measurement more accurate and reliable. 4, the confidence measure of the instrument is the only all domestic like product in accordance with the national standard GB/T16292-1943896 two conditions, automatically determine the level of purification. 5, can store 300 measurement data to support queries. Users can also purchase a complete set of computer data analysis software, data management post-6, the user can choose the temperature and humidity measurement accessories. 7, took the lead in the domestic like product sampling flow with digital display, which is more intuitive and more accurate. 8, the use of advanced lithium batteries, safer, more durable, less than five hours of continuous use. V.
