1productOverview：

　　The LB-3000 (B) air sampler is a multifunctional air sampler developed according to the JJG956-2013 "Verification Regulations for Air Samplers" standard, which meets the requirements of GBZ159-2004 "Sampling Specification for Monitoring Hazardous Substances in Workplace Air". It can be used for monitoring by environmental protection, occupational health, enterprises, education, scientific research, labor, safety supervision and other departments.

　　IIProduct Features：

1Dual use of dust and poison:Multiple air collectors are matched to meet the sampling requirements for dust, metal, fluoride and other dust chemical factors, as well as toxic substances such as SO2 and NOx. Both fixed-point and individual sampling are compatible.

2. Advanced modulesChemical programming:

◆conciseProgram the sampling pump using a 5-key keyboard operationChinese operation menu, real-time display of instrument working status on wide temperature LCD screen.

　　◆four typessamplingModule selectionDelayed sampling, manual sampling, timed sampling, interval sampling;

　　◆Automatic Memory DataReal time recording of accumulated sampling dataIt can store up to 1000 sets of sampling data, automatically save data when powered off, and continue sampling when powered on.

　　◆Interval samplingThe time can be set arbitrarily at 99 hours and 59 minutes, with a sampling frequency of 1 to 99 times; This feature extends short-term sampling to sampling over a longer period of time to meet the TWA sampling requirements with fewer samples.

3Two level bufferingAnd anti backflow suctiondeviceIt can effectively reduce the damage of air flow pulses, reagents, and particulate matter to the pump, maintain stable flow, and extend the service life of the pump.

4Dual use of AC and DC:4. Advanced high-capacity lithium-ion batteries,battery lifeability≥twenty-twohour.

5. Split type battery installation box, convenient for customer maintenance.

Maintenance and Precautions

　　1. The instrument can discharge on its own without turning off the power switch, and should be regularly recharged; When not in use, the power switch should be turned off to avoid over discharge and damage to the battery.

　　2. If the instrument experiences backflow, it should be cleaned promptly with anhydrous ethanol. The instrument is inverted and in an unloaded working state. After inhaling anhydrous ethanol, repeat this method several times until the ethanol evaporates before resuming normal use.

　　3. If the instrument has been in use for a long time and the flow rate is unstable or the float is not flexible, the flowmeter should be cleaned and dried before use.

　　4. Our company's products come with a one-year warranty from the date of sale. If any non-human quality issues are found within one month, replacement or repair can be requested.

　　5. It is strictly prohibited to charge in flammable and explosive environments.
