EA125 Microbial Air Sampler

HKM-II Microbial Air Sampler

Introduction

Widely used in pharmaceutical company, milk product plant, clinical operation room, fermentation industry et al, where microbial contamination need to be strictly monitored and controlled. Also it is applicable in institutes that need study the air microbial condition.

 Features:

 1. Automatic air flow compensation:

With built in real time air flow monitor sensor, automatically compensate air flow, avoid air flow divergence caused by medium volume in Petri dish et al. ( HKM-II B)

2. Constant sampling speed: 

Sampling opening wind speed almost same with clean room wind speed, which more accurately reflect microbial concentration of the clean room, and optimizes impact speed, making false positive result get controlled and guarantees microbial sampling efficiency.

3. User friendly interface:

Simple keypad making menu navigation easy, with all sampling information clearly displayed on LCD. The LCD can also monitor sampling amount (0.01-6.0 m³). And user can easily set sampling place code, sampling rate, language, time etc.

4. High efficiency: 

Not need to buy and use special test paper or filter membrane.

5. Sampling direction adjustable:

Sampling head adjustable from horizontal to vertical, can meet multi-angle sampling requirements. Also it is light enough to hold while sampling, or can be mounted on a tripod (tripod is optional by order). 

6. Data traceability:

Every sampling run generates a unique record, which is stored in the unit (holds up to 2000 records). The data is easily accessed and read on the LCD. For HKM-II A and HKM-II B sampler, also built in software which allows data to be downloaded to computer for reporting, printing and analysis.

7. Long time working:

When fully charged, it can work up to 15 hours continuously using battery, which is high volume rechargeable polymeric lithium battery, it has no memory effect, is safe and durable.

8. 95% sampling efficiency: 

Validation work according to BS EN ISO 14698-1:2003 Annex B and Annex C, as carried out by an independent laboratory, which has shown the air sampler have a physical efficiency of 95% for particles 0.8 to 19.0 micron in size.

 Technical Parameter

 Collection Efficiency: Physical efficiency was determined using Bacillus subtilis spores and a membrane filter reference method (BS EN ISO 14698-1:2003 Annex B).
