Overview

• The Extech VPC300 is a handheld environmental measuring instrument distinguished by a built-in camera that captures 3GP video and JPEG photos, tying the numerical reading to the dust source in a single report — solving the most practical problem in air quality reporting: proving where a reading was taken, not just how high it was. The instrument measures six channels of particle sizes: 0.3 · 0.5 · 1.0 · 2.5 · 5.0 · 10 µm, at a flow rate of 0.1 ft³ (2.83 L/min) driven by an internal pump, in three counting modes: cumulative, differential and concentration. It also measures air temperature from -25 to 60 °C with ±1 °C accuracy, relative humidity from 0 to 100% with ±3% accuracy (within the 40-60% band), plus dew point and wet bulb from 0 to 50 °C. The display is a 2.8-inch colour TFT, internal memory of 74 MB holds 5000 records and 20 minutes of video, and a microSD card up to 8 GB is supported (card not included), with a Mini-USB port and a tripod mount for continuous recording. The meter is NIST calibrated and ships with a traceable calibration certificate, in a complete kit comprising a universal charger, USB cable, PC software, tripod, filter, a 7.4 V NiMH battery and a hard case. Dimensions are 240 × 75 × 57 mm and weight 570 g. The environments it serves include: diesel vehicle transportation and service depots, fossil-fuel power generation, traffic-related emissions, charcoal-based heating and cooking, cement manufacturing, mining and stone crushing, metallurgy processes (melting, pouring, torch-cutting), and agroindustrial work. Available through Al-Najma Al-Wataniyah with guaranteed quality and fast delivery across Riyadh, Dammam, and all KSA regions.

Technical Specifications

Size & Color Table

• The instrument is offered as a single model (VPC300) covering the six channels and measurement ranges listed in the technical specifications, supplied as a complete kit in a hard case.

Documentation & Standards

• The instrument carries the CE mark and ships NIST calibrated with a traceable calibration certificate with every unit — the point that matters most to an institutional buyer, because the calibration certificate is what makes the readings acceptable in environmental and compliance reports and in internal audits. The six particle channels are sampled at a fixed flow rate through an internal pump, with temperature and humidity logged in the same record, so every reading is documented with its time and conditions.
• Additional reference standards for the Saudi market:
• ISO 21501-4 (calibration of light-scattering airborne particle counters) — the reference standard for calibrating this class of instrument
• ISO 14644-1 (classification of air cleanliness in cleanrooms) — the reference defining sample volume and flow requirements
• ISO/IEC 17025 (competence of calibration laboratories) — to confirm the accreditation of the certificate issuer
• CE marking — the European conformity framework covering electromagnetic compatibility and electrical safety

Frequently Asked Questions

Q1: Where does this instrument excel in practice?

• In surveying, monitoring, source identification and verifying filter and ventilation performance. It is handheld with an internal pump and six measurement channels, and it combines the reading with temperature, humidity and video in a single record, giving a safety department the full picture of where and when a problem occurs rather than a bare number.

Q2: What does 50% counting efficiency at 0.3 µm mean?

• It is the standard way light-scattering particle counters are calibrated: the smallest channel is calibrated at 50% efficiency, reaching 100% for particles above 0.45 µm. Readings on the smallest channel are read as a statistical indicator of trend, while the larger channels give direct counts.

Q3: What does the 2,000,000 particles per ft³ coincidence limit mean?

• It is the maximum concentration at which the instrument maintains counting accuracy. In heavily dusty environments the sample is taken at a suitable distance from the source to stay within that range, which is standard practice for crusher and smelter measurements.

Q4: What is the practical value of the built-in camera?

• It ties the number to its source: instead of a report stating a high reading at some location, you have video and a photo of the moment of measurement attached to the record. That shortens arguments in environmental and compliance reports and makes before-and-after evidence of a corrective action straightforward.

Q5: Is delivery available to Riyadh, Dammam, and all KSA regions?

• Yes, supply is available across all KSA regions, with bulk quantities available for B2B projects and for equipping safety departments and laboratories.
