A.Principle introduction

FKC-1 Microbial air sampler is a highly porous inhaled dust sampler. It according to the design theory of isokinetic sampling, the sampling directly, collecting head wind speed and clean indoor air velocity is basically the same, can more accurately reflect the clean indoor microbial concentrations. When sampling, with dust air speed through a microporous, is uniformly impinging on the culture dish on the agar surface; these living microorganisms on the surface of the agar to obtain nutrition uniform and sufficient, in the training process, fast dynamic process of water, high speed growth, resulting in faster that results.

Two. Use the environment

1 temperature: 35 - 10

2 relative humidity: 10 - 90RH

3 atmospheric pressure: 80 - 110kPa

4 maximum dust concentration: 100000000 M / m or @0.5 fand fand 0.2mg/m

5 maximum wind speed: 1m/s

Three. Main features and parameters

1 sampling head for numerous micro pores, so that the microorganisms evenly distributed on the agar surface, reducing the overlap of the dust bacteria, reducing the microbial count error.

2 sampling flow: 100L/min

3 sampling head flow rate: 0.38m/s and clean indoor air velocity is basically the same (constant sample).

4 sampling quantity can be set from the 0.01 - 6.0m fand any.

5 using the standard general Petri dish diameter 90*15.

6 power supply: AC and DC, rechargeable battery DC7.4V, charging power after the continuous work of 4h.

7 Dimension: diameter 120*300

8 weight: 2.5kg

Four. Structural characteristics description

1. The sampler is composed of the two parts, the upper part of the sampling head, a Petri dish seat, pump sampling, sampling pump seat, sampling pump power. The lower part is the control board, memory, LCD display, keyboard and battery module.

2. The sampler can make DC dual-use, the instrument below a switch and a socket (see photo), when using the DC switch is powered by the battery; when using the AC will randomly configured 8.4v power adapter is inserted into the jack. When the switch is not open at this time in a state of charge, when the switch is opened, by 8.4v power adapter, power supply and maintain state of charge.

Five. Operating instructions

1. Unloading porous sampling head, with training base diameter of 90mm diameter Petri dish placed in culture dishes, and the culture dish adjustment as the basic level, adjustable locating rod so that the positioning rod groove and training base in the same horizontal plane, packed porous sampling head.

2. Turn on the power switch, the display screen display on a sampling data and sampling time. At this time press up key or down key can view historical data in memory, according to the "stop" button can make the system into the sampling ready state, at this time the show the current date and time, sampling value is displayed as a zero.

3 remove the protective cover".

4. According to the "sampling" key system into the sampling state, according to delay time to start sampling pump and counters. At this time, the sampling volume gradually accumulate until and set equal to the amount of sampling, automatic stop counting, closed sampling pump, the current sampling amount and date and time are saved in the internal memory.

5 in the sampling work state press "stop" button will terminate the sampling work, close the sampling pump, stop the sampling amount of the cumulative, and then press a "stop" button will clear the current display, enter the sample preparation state.

6 press "function" key to enter the parameter setting state, each state parameter setting is as follows:

(1). The amount of sampling set: in this state, the press keys adjust sampling quantity, sampling quantity, the range of 10-6000, adjustment step distance of 10 liters, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

(2). Sampling delay time setting: in this state by keys adjust the sampling time delay and sampling time delay range is 0-256 seconds, the adjustment step distance is 1 second, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

(3). Backlight delay time setting: in this state, according to keys, delay time adjusting backlight, backlight delay time range is 0-256 seconds, the adjustment step distance is 1 second, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

(4) contrast adjustment: in this state, by pressing up and down keys to adjust the contrast of LCD display, contrast range of 0-3, press the "stop" button to exit the parameter settings, press the function key to enter the next parameter setting.

(5). Set the time: in this state press on button can adjust the current cursor position time, according to the "confirmation" button to change the cursor position, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

(6). Set the date: in this state press on button can adjust the current cursor position date, according to the "confirmation" button to change the cursor position, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

(7) sampling volume correction: in this state, by pressing up and down keys to adjust the sampling value, that is, the measured flow value per minute. Adjust the range of 20-200 L / min, adjust the step distance to 1 L / min, press the "stop" button to exit the parameter settings, press the "function" key to enter the next parameter setting.

(8). Clear the settings: in this state according to the keys to adjust the zero state, in a cleared state press "confirm" button will be the memory of historical data removal and exit the parameter setting mode, press the "stop" key to exit the parameter setting, press the "" key to enter the next parameter setting.

Six. Maintenance, maintenance and use of matters needing attention

1. Not selected toxic corrosive gases, not in strong acid and alkali environment, not in the dust concentration is greater than 0.3mg/m the university environment use.

2 do not remove the "protective cover" shall not press the "sample" key.

When the battery pattern is displayed on the 3 display screen, the battery quantity is insufficient, and the sampling flow rate is small, and the sampling quantity is not accurate.

4 when installing the culture dish, the dish must be in place and should be stuck, and the culture dish is adjusted to the basic level.

5. To culture dish adjustment as the basic level, adjustable locating rod, the positioning rod groove and culture based on the surface in the same horizontal plane.

6 after each use, the use of alcohol will be "sampling head" and "protective cover" paint clean, and the "protective cover" cover good "sampling head".

7 long time not to use, should be placed in the box, and at least once a month, each time not less than 10 minutes.

Seven. Common fault handling

Common faults

Cause of failure

processing method

According to the "sample" key, the sampling pump does not work

1 handle internal wire break

2 sampling pump power supply is bad

1 handle wire connection

2 change sampling pump power supply

 

 

Small sample flow

 

1 battery voltage is low

2 sampling head micro hole plugging

3 too much liquid culture dish

1 plug in the power charge

2 cleaning sampling head

3 culture dish to the designated position

Turn on the power switch, the display screen shows that the abuse of code or control key does not work

The sampler computer crashes

The power switch is turned off after more than 5 seconds after the boot
