Clarity detector

I. Overview

YB-2L typeClarity detectorIt is a lamp detector developed based on the first method (lamp inspection method) in the current version of the Chinese Pharmacopoeia's Visible Foreign Matter Inspection Method 0904 and the various provisions of the inspection device in the clarity inspection rules and judgment standards issued by the Ministry of Health of the People's Republic of China WBI-362 (B-121) 91. Suitable for clarity testing of various types of injections, large infusion solutions, and bottled medicinal liquids.

2、 Performance characteristics

YB-2L typeClarity detectorDesigned in accordance with standard regulations, equipped with reflective shading and light guide plates, with a non reflective black background, a non reflective white movable background and bottom plate, and an extended bottom plate design for convenient large capacity liquid medicine detection;

The top adopts a specially designed diffuse reflection LED fluorescent lamp, which reflects the light to eliminate shadow interference after mixing, with a maximum illumination of>10000Lx, while increasing the service life and reducing the cost of use;

The light source design eliminates flicker, improves visual inspection resolution, has a color temperature of 6000-6500K, and reduces visual fatigue;

Adjustable illumination, capable of achieving single digit level illumination adjustment;

The illuminance measurement device supports separate measurement (optional);

The detection time limit can be set arbitrarily from 1 second to 99 hours (seconds, minutes, hours) (factory default: seconds), and it has a timing prompt function;

Equipped with a foot operated timer start switch for easy operation.

4、 Instrument installation operation

1. Place each testing whiteboard in the corresponding position according to the pharmacopoeia regulations; Insert the foot switch plug into the socket on the back panel of the instrument.

2. Connect the power cord and turn on the power switch.

3. Adjust the required illuminance according to the pharmacopoeia requirements:

Rotate the "illuminance adjustment knob" clockwise to light up the LED fluorescent tube; Open the cover of the "handheld metering probe" and place the probe facing the light source at the position of the sample to be measured to measure the illuminance. At the same time, adjust the "illuminance adjustment knob" until the illuminance meter measures the required illuminance value for sample detection (note to select the correct range on the handheld metering probe). After adjusting the illumination, cover the handheld metering probe with the lid and use the magnet on the back of the probe to attach it to the position shown in the picture, and store it properly.

4. According to the requirements of the tested drug, set the required testing time:

The factory default timer duration is 20 seconds. If you need to modify it:

Press the "" key on the "timer", and from right to left, correspond to the digits, tens, hundreds, and thousands of the set value. Click on the value to increment.

5. Start timing:

There are two ways to start:

Press the 'timer reset and start composite manual switch' and then release it;

Press the 'timer start foot switch' once.

The two methods can be freely selected based on the experimental site conditions and the convenience of the experimenter's operation, and have the same effect.

When the time is up, the timer indicator light will turn on.

If you need to start the timer again, press the "timer reset and start composite manual switch", then release it. At this time, the "timer indicator light" will turn off and start the next countdown.

5、 Precautions

The power supply of the instrument must have a protective grounding wire and be well grounded

Ensure the safety of instrument use and operators!

Before replacing the lamp, the power must be cut off!

If there is any medicine left in the machine, it should be removed in a timely manner to prevent it from flowing into the electrical box and causing other accidents.

6、 Instrument maintenance

Please do not place this instrument in damp, windy, sunny, or rainy places. Before using the instrument, please check the power cord and plug. To clean the inner wall of the lightbox, use a soft object such as a brush or soft cloth. If the lamp does not light up, first check the fuse and power supply, and then check the contact of the lamp.

**Calibration and selection of handheld metering probes

1. Calibration:

The handheld metering probe standard on this machine can be calibrated before and regularly according to different usage requirements. The calibration method is as follows:

1) Prepare a high-level, metrologically validated illuminance meter;

2) Select several illuminance values required for the experiment as calibration points. For example, if the required illuminance values for the inspection of the sample are 1500Lx, 5000Lx, 9000Lx, etc., then these points should be selected as calibration points;

3) Place the photometric probe of the illuminance meter in the instrument inspection area, where the sample will be placed during future experiments (this position is suitable for the convenience of the experimenter to operate and observe). Adjust the dimming device on the instrument to display the illuminance reading of the illuminance meter as one of the calibration points, such as 1500Lx, and record the reading of that reading;

4) Remove the metering probe of the illuminance meter, place the randomly configured metering probe of the instrument at the measurement position, and read the reading of the handheld metering probe;

Illuminance indication reading - handheld metering probe indication reading=handheld metering probe correction value

For example, if the illuminance reading is 1510Lx and the handheld metering probe reading is 1410Lx, then the correction value of the handheld metering probe at the 1500Lx point is+100Lx.

Create a label for the correction value and attach it to the handheld metering probe.

5) The remaining calibration points shall be calibrated according to the above method.

6) When using a handheld metering probe for illuminance measurement in daily life, simply add or subtract the correction value of the corresponding illuminance point.

2. Configuration selection:

1) Normally, our company recommends using the handheld metering probe that comes standard with the device for instrument configuration, and calibrating the metering probe using a value transfer method. This not only meets the requirements of instrument verification and usage, but also has good economy.

2) If there are clear requirements for the usage scenario of this machine, it is not allowed to use the measurement value transmission method, and the metrological verification method must be used, then our company suggests changing the standard handheld metering probe to an optional high-level professional illuminance meter when selecting the configuration.

High level professional illuminance meters can be purchased from measurement instrument manufacturers or purchased from our company. At the same time, our company also provides measurement verification services.

3. Regarding the measurement error of the professional level illuminance meter: The professional level illuminance meter configured by our company is produced by a professional illuminance meter manufacturer. If there is a measurement error, our company can provide replacement service for the illuminance meter within one month after purchasing the product.
