What are the technical features of the ZR-3620 small flow gas sampler?
Date: 2025-10-21Read: 6
ZR-3620A/B/C small flow gas sampler is an instrument for collecting gaseous samples in atmospheric and pollution source pipelines. Its working principle is to use a sampling pump to extract samples, and achieve quantitative collection through stable flow measures and synchronous timing methods. This sampler can be used for short-term or long-term collection of harmful gas samples such as TVOC in the air for environmental monitoring stations, health and epidemic prevention, labor protection, epidemic control centers, engineering quality indoor testing, scientific research units, colleges and universities, and environmental protection personnel in industrial and mining enterprises.
What are the main technical characteristics of small flow gas samplers? Below, the editor will briefly introduce to you:
● Long battery life: Equipped with a rechargeable high-performance lithium battery, it can work continuously for more than 20 hours when fully charged.
● Free selection of sampling modes: immediate sampling, timed sampling, and volumetric sampling.
● Instrument compatibility: adsorption tubes with multiple specifications, different filling materials, and lengths.
● Multi purpose: equipped with sampling functions such as filter membrane, activated carbon tube, and solution absorption.
● Human Machine Engineering: Compliant with human machine engineering design, using high brightness LCD screen.
Automatically measure ambient temperature, atmospheric pressure, pressure and temperature in front of the flow meter, calculate reference volume and standard condition volume. Small in size, lightweight, and easy to carry.
Strong negative pressure: The maximum load capacity exceeds 30kPa, making it easy to handle high resistance enrichment carrier sampling (benzene derivatives, TVOC, etc.), using imported diaphragm pumps.
Digital constant current: Built in high-precision electronic flowmeter, accurate closed-loop control, original flow control algorithm, ensuring precise control of small flow rates.
● Multiple protection: Efficient protection design of the intake filter.
