HHQ-II 大气采样器

采样流量范围(可选)：0.1－1.5L/min、0.1－2L/min、0.1－3L/min

  流量误差：≤±5％

  定时误差：≤±1％。

  采样负压；≥25000Pa

  工作电压：10VDC、220V、50Hz AC

  工作温度：－10～45℃

  相对湿度：≤85％

  重量： 约2Kg

采样：用适当的胶管将仪器背面的进气口与被采样负载连接，按压开关键到“ON”打开仪器，再按压微电脑“确定/取消”键，显示屏出现“0：00”，接着按压“分”选择所需的时间，此键zui大时间为59分，若59分不够，再按压“小时”键，此键zui大时间为99小时，当时间选择好好后再按压“确定/取消”键即开机采样。采样泵工作的同时电脑进入状态，当电脑显示屏显示"0：00"时，主机此次采样结束。如需再次采样，重新设定时间继续采样，如果不需采样，请按压开关键到“OFF”关闭仪器。

充电：将交流电源线分别插入仪器220V交流输入端与，市电，仪器处于关机状态，一次充足电约需14～16小时(标准充电时间)。每次充足电可连续工作或累计工作8小时左右。

在采样时电压表所指示采样时的电池电压，在充电时所指示充电时的电池电压。充足电电压表指示为12V左右。

注意事项：当机内电池电压低于8V，应对电池充电，若较长时间不用(3个月以上)，应进行补充电，以确保高能锂电池的使用寿命。在采样过程中，应接上安全瓶，以保护气泵及气路安全。

HHQ-II Atmospheric Sampler Description:
2. Double - channel air sampler is a kind of conventional instrument for the parallel sampling of harmful gases. The instrument uses two pumps independently to complete the two groups of gas, do not interfere with each other, the circuit using the latest microcomputer chip control technology, built-in high-energy lithium rechargeable battery, continuous operation for a long time, easy operation, high precision, durable, AC-DC compatible When convenient.

Sampling flow range (optional): 0.1-1.5L / min, 0.1-2L / min, 0.1-3L / min

Flow error: ≤ ± 5%

Timing error: ≤ ± 1%.

Sampling negative pressure; ≥ 25000Pa

Operating voltage: 10VDC, 220V, 50Hz AC

Working temperature: -10 ~ 45 ℃

Relative humidity: ≤85%

Weight: about 2Kg

Sampling: Connect the air inlet on the back of the instrument to the sampled load with the appropriate hose, press the ON / OFF key to turn on the instrument, and then press the "OK / Cancel" key of the microcomputer, the display will show "0:00" "Minute" to select the required time, the maximum time for this key is 59 minutes, if 59 points is not enough, then press the "hour" button, this key maximum time is 99 hours, when the time is selected and then press "OK / Cancel" That is, boot sampling. When the sampling pump is working, the computer will enter the countdown state. When the computer display shows "0:00", the host will finish the sampling. If you need to re-sample, reset the time to continue sampling, if you do not need to sample, press the switch to "OFF" to turn off the instrument.

Charging: Insert the AC power cord into the 220V AC input terminal of the instrument, and the utility power and instrument are in shutdown state. It takes about 14 ~ 16 hours (standard charge time) to fully charge the AC power cord. Each time fully charged can work continuously or accumulative total of 8 hours.

The battery voltage at the time of sampling indicated by the voltmeter at the time of sampling, and the battery voltage at the time of charging indicated at the time of charging. A full voltmeter indicates about 12V.

Note: When the battery voltage is lower than 8V, the battery should be charged, if not for a long time (more than 3 months), should be added to ensure that the high-energy lithium battery life. In the sampling process, should be connected to the safety bottle to protect the air pump and gas safety.
