Detailed Product Description
Product Introduction of TW-2010 dual-channel constant temperature automatic continuous sampler
■ AC and DC dual-use, built-in lithium battery, ultra-long power supply time;
■ Semiconductor refrigeration technology, no pollution, high refrigeration efficiency;
■ Electronic flow meter, no flow fluctuation, constant current sampling, any one channel can be controlled separately;
■ High-speed processor automatically calculates and controls the sampling flow, and automatically compensates for flow changes caused by voltage fluctuations and resistance changes;
■ During the sampling process, the system power supply status is automatically monitored. When the AC power is disconnected or the built-in lithium battery voltage is low, the current sampling status is automatically memorized, and the previous sampling is automatically restored when the power is restored;
■ Power saving protection function: When the system is in standby mode and not working under battery power, it will automatically shut down after one hour of power on, saving battery power to the maximum extent;
■ Pipeline blockage protection function: During the sampling process, if the pipeline is blocked or the load is too large, the system will automatically stop the pump to protect the instrument from damage due to long-term overload. If the load is greater than minus 20kPa for a long time, the protection function will be automatically started;
■ Automatically measure the ambient atmospheric pressure and temperature, display the real-time sampling flow, cumulative sampling volume, standard volume, and reference volume;
■ The gas circuit is equipped with an anti-backflow drying bottle to prevent the absorption liquid from backflow;
■ Automatically measure the ambient temperature, with constant temperature automatic heating and cooling functions, and the cooling temperature is adjustable (15-30)℃;
■ Equal interval sampling, the number of sampling times can be set arbitrarily between 1 and 99 times;
■ Built-in real-time clock, the sampling start time can be set in advance;
■ High-performance subwoofer brushless diaphragm pump with long service life;
■ Chinese LCD display with automatic contrast adjustment can work normally at minus 30 degrees;
■ Equipped with RS232 digital communication interface, it can be connected to an external thermal printer for convenient data output.
TW-2010 dual-channel constant temperature automatic continuous sampler uses solution absorption method to collect various toxic and harmful gases in the ambient atmosphere and indoor air. It can be used for routine or emergency monitoring of gaseous substances in environmental protection, health, labor, safety supervision, construction, military, scientific research, education and other departments.
