HT9600 Indicative Particle Counter
We have been trialling this unit for two years now, often alongside our professional Casella CEL-712 particle counter ……. and its performance in the field is very impressive for the price!!
Built in China and not as rugged as the Casella unit but at a fraction of the cost. The leaflet, (in very interesting English), asserts that error margin is <20%. In practice it appears to be well within that margin.
Simple to use and set up – this instrument is ideal for conducting indicative qualtitative checks, eg at LEV TExTs, on break-through levels from recirculating dust filters.
This is an ‘Indicative’ monitor – but it will identify very effectively if there is any significant break-through occurring. It will also provide generic indications of the levels of PM10 and PM2.5 at break-through.
We would still use our Casella CEL-712 for occupational hygiene monitoring projects ….. but the HT9600 …. has so many practical applications – and, as indicated, – especially for filter breakthrough checking. The instruction leaflet asserts that error margin is <20%. In our field trials with this unit it appears to be well within that margin.
Not suitable for calibration (due to purchase cost being so low) – but in the field we run it (eg in an office) in a ‘clean’ air environment; note the values recorded and use that as a relative indicator when checking the outlets from recirculating filters.
Has 2 chanels which run in parallel; PM10 and PM2.5.
Do bear in mind that the display is in μg/m3 so you need to divide by 1000 to get mg/m3. Also measures Temperature and Humidity.
