Overview
CQB5000 is a new (explosion-proof) individual sampler designed specifically for long-term or individual sampling of occupational hazards in the workplace! It can be used for individual sampling of dust toxins such as metals and fluorides, as well as for fixed-point sampling of substances such as TDI, MDI, and odors; After adding a constant pressure multi tube sampling module with a constant flow rate, multiple groups of substances can be collected simultaneously. The instrument adopts an Exibl (150 ℃) level intrinsic safety explosion-proof structure, which is particularly suitable for use in coal mines and other workplaces containing explosive gases!
Product Details
Product Features:
Digital constant current ：Built in high-precision sensors, precise closed-loop operationControl, you don't have to worry about your flow rate deviating, it can be automatically calibrated by yourself, and the instrument is within<-20℃,>60 ℃Under certain circumstances, high and low temperature protection can be activatedProtective function, temperature display, real-time temperature and pressure compensation!
Long-lasting battery life Charging time≤ 5 hours, can work continuously for more than 40 hours when fully charged, no need to arrange charging before each work, built-in large capacity lithium battery pack, with battery level detection, automatic alarm prompt when the battery level is low!
Multi tube sampling Multiple flow modules can maintain a constant pressure, eachThe flow rate can be set separately for multi tube sampling, with four sampling modes available: manual, timed, constant volume, and programmed!
Multiple Protection Efficient protection design of intake filter, anti slip of the whole machineThe sampling nozzle is anti drop, and the pre drying anti backflow suction bottle provides multiple protections to prevent particle and moisture damage to the instrument. The intelligent flow calibration system can choose between single point and linear calibration modes!
*Negative pressure At a flow rate of 2000ml/min and a resistance of 25KPa, the flow error is better than ± 4% atmospheric pressure display, and the maximum load capacity exceeds 25Kpa, making it easy to handle high resistance enrichment carrier sampling (TVOC, benzene derivatives, etc.)!
combined use ：Can be used in combination with multiple units to achieve series, parallel, and multiple connectionsSampling of various substances, multiple sampling methods, waist carrying sampling, tripod connection sampling, dual channel combination sampling, four-way combination sampling, etc!
