Frequently Asked Questions: Particles Plus 8303 Handheld Particle Counter:

1/ What particle size range does the 8303 measure?

The Particles Plus 8303 measures particles from 0.3µm up to 25.0µm using three user-selectable size channels.

2/ How many channels can I configure and at what sizes?

You can configure up to three size channels anywhere between 0.3µm and 10µm, plus a total particulate mode (TPM) that counts particles up to 25.0µm.

3/ What flow rate and counting efficiency does it offer?

It draws air at 0.1 CFM (2.83 LPM). Counting efficiency is 50% at 0.3µm and 100% for particles larger than 0.45µm.

4/ How much data can it store onboard?

The 8303 holds up to 45,000 sample records, 1,000 distinct sample locations, and 50 measurement recipes for routine testing.

5/ Which physical interfaces are available?

Standard interfaces include Ethernet and USB. Optional modules provide Wi-Fi, RS-485, and RS-232 connectivity.

6/ Can I print or export reports directly from the unit?

Yes. You can connect a compatible thermal printer via USB or Ethernet, or export data to a USB flash drive in CSV format for later analysis.

7/ How does remote monitoring work?

With the optional Wi-Fi module or Ethernet connection, the device can stream live data and diagnostics to a central server or be controlled via a web browser interface.

8/ How do I synchronize sample location identifiers?

Using the bundled IMS Software, you map each location to a digital floor plan or assign alphanumeric tags. The software pushes location lists to the counter and pulls back timestamped results.

9/ What software is provided for data analysis?

The IMS Software suite lets you configure the instrument, download stored records, generate reports in ISO 14644-1, EU GMP Annex 1, FS 209E, or custom formats, and visualize trends.

10/ In which file formats can I export data?

You can export in CSV for spreadsheets, XML for integration, or PDF for finalized reports.

11/ Can I customize report templates?

Yes. IMS Software includes a report designer to add your company logo, define threshold limits, and adjust report layouts.

12/ How often should the 8303 be calibrated?

Particles Plus recommends an annual calibration using a NIST-traceable master aerosol generator to verify sizing and counting accuracy.

13/ What does routine maintenance involve?

Wipe down the enclosure with a mild, non-abrasive disinfectant. Inspect the sampling inlet for blockages and replace the internal filter element yearly or after a specified cumulative sample volume.

14/ How do I know when to clean or replace optical components?

If background counts (zero count) exceed 2 particles/ft³ over a five-minute purge, or if readings drift beyond specifications, send the unit for service. Remote diagnostics can also flag optical misalignment.

15/ What is the battery life during continuous sampling?

On a full charge, you can expect over 10 hours of uninterrupted sampling at 0.1CFM.

16/ Is there a low-power or standby mode?

Yes. In standby, the 8303 can maintain clock and memory for up to 100 hours before needing a recharge.

17/ How long does it take to recharge?

The onboard Li-ion battery typically recharges fully in 4 to 6 hours using the supplied AC adapter.

18/ What display and controls are provided?

A large, color touchscreen with icon - driven menus guides you through setup, real-time metering, Particles/ second readings, and alarm threshold configuration.

19/ How do I set alarm thresholds?

In the device menu, define upper and lower limits for any size channel or mass concentration. Visual (LED) and audible alarms will engage when counts exceed those limits.

20/ Can I view real-time particle counts?

Yes. The Real - Time Meter mode shows live counts per second, counts per cubic meter or cubic foot, and mass concentration in µg/m³ (with density correction).

21/ What environmental sensors are available?

Standard models include temperature and relative humidity probes. You can add optional CO2 and TVOC sensors for comprehensive IAQ assessments.

22/ What mounting or carrying accessories can I use?

The 8303 has a built-in 1/4″ - 20 female tripod mount. Available accessories include a handheld probe extension and a hard carry case.

23/ Are there calibration kits or filters for purchase?

Yes. Particles Plus supplies NIST - traceable aerosol generators, certified filter sets, and isokinetic inlets as factory options or field-service kits.

24/ What do common error codes indicate?

- E01: Flow fault - check for inlet blockage or pump failure

- E02: Laser alignment - send unit for optical realignment

- E03: Memory error - back up data and contact support

25/ What warranty and service plans exist?

The warranty period is 12 months from the date QTE TECHNOLOGIES dispatches the goods: https://qtetech.com/en/warranty-policy
