HL5000 digital constant current sampler Introduction: The HL5000 atmospheric constant current sampler is equipped with a built-in flow sensor and uses PID control algorithm to achieve precise flow control. The sampled flow rate is accurately displayed. Adopting a large LCD screen that is easy to read for display. Powered by a self-contained battery, it has a long power supply time and can operate continuously for more than 12 hours under normal sampling conditions. Equipped with a programmable controller, users can program sampling according to their own needs, allowing up to 3 predetermined sampling schemes. Additional power indicator, overload and over limit indicator, dust filtration at the injection port, dual channel simultaneous sampling, simple operation. During the sampling process, the digital display shows the remaining sampling time, sampling flow rate, and cumulative sampling volume. It has the advantages of compact structure, small volume, light weight, easy to carry, sturdy and durable, strong load capacity, accurate and stable flow display, and low noise. It can be carried around during operation and is a more user-friendly gas constant current sampling instrument. The HL series constant current sampler meets the basic requirements for air samplers, such as GB50325-2020 "Standard for Indoor Environmental Pollution Control of Civil Building Engineering", GB/T 17061-1997 "Technical Specification for Workplace Air Sampling Instruments", HJ/T 400-2007 "Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles", etc; Widely applicable for indoor monitoring, environmental monitoring, industrial and mining enterprises, and health and epidemic prevention departments to collect various toxic and harmful gases; Dual gas path independent sampling (detachable), combined with absorption tubes, used to collect gases such as formaldehyde, ammonia, TVOC, benzene, etc. in the air. Technical parameters: Flow range: (1-5) L/min Flow error: ≤± 5% Traffic repeatability: ≤ 2% Flow stability: ≤ 5%/8h Load capacity: When the flow rate is 2L/min, it can overcome a resistance of 5kPa Timing range: 1 to 9999 minutes Timing error: ≤± 0.1% Applicable ambient temperature: (-10~55) ℃ Continuous working time: ≥ 12h Host dimensions: Single air path 130mm × 100mm × 70mm; Dual gas path 250mm × 150mm × 150mm Weight: 650g per air circuit; Dual air circuit 2.8kg
