HHAQ-107-Meter

Supported Applications

The Omega HHAQ-107 is a handheld instrument designed for making ballpark measurements of mixed-gas volatile organic compound (VOC) levels as part of an indoor air quality (IAQ) maintenance program. It utilizes a metal-oxide semiconductor sensor within a vented ball housing to detect ammonia, toluene, ethanol, hydrogen sulfide (H2S), and cigarette smoke.

The device is intended for spot-checking concentrations of mixed-gas VOCs rather than precise single-gas measurements. In addition to total VOC concentration, the meter measures ambient temperature, relative humidity (RH), dew point, and wet bulb temperatures.

Operating Conditions & Performance

The HHAQ-107 operates within an ambient temperature range of 0 to 50°C (32 to 122°F) at 0 to 95% RH, non-condensing. The instrument features a large backlit dual-readout LCD with a 51 mm (2") diagonal display.

Performance specifications for the series include:

• VOC Measurement Range/Resolution: 0 to 50 ppm / 0.01 ppm
• VOC Warmup Time: 10 minutes first use, 2 minutes thereafter
• Temperature Measurement Accuracy/Resolution: ±0.6°C (1.2°F) / 0.1°
• RH Measurement Range: 10 to 90% RH
• RH Measurement Accuracy/Resolution: ±5% of reading at 25°C (77°F); ±7% of reading elsewhere in range / 0.1% RH
• Dew Point Measurement Range: -73 to 47°C (-99.2 to 118°F)
• Wet Bulb Measurement Range: -11 to 48.2°C (12.2 to 118.8°F)

The device includes an adjustable high VOC concentration audible alarm, min/max memory for all measured parameters, and a data hold function.

Data Logging & Power

• Capacity: Logs up to 32,004 points. The entire capacity can be devoted to VOC readings or divided one-third each among VOC, ambient temperature, and RH readings.
• Interface: USB cable included for connection to a PC-compatible data logging program on mini-disc.
• Power Source: (6) 'AAA' batteries (included) or included 110 Vac adaptor.
• Auto Power-Off Trigger: 15 minutes of front-panel inactivity (can be disabled).

Configuration Options

The HHAQ-107 series is offered as a single handheld configuration with the following documented capabilities and included accessories:

• Housing Material: Black and yellow plastic housing.
• Sensor Type/Longevity: Metal-oxide semiconductor / 5 years (typical).
• Data Logging Modes: Software supports four data logging modes, including starting and stopping recording without a PC.
• Calibration Features: Automated VOC zero adjustment procedure; manually offsettable temperature and RH sensor drift.
• Mechanical Mounting: Tripod mountable design.

The package includes the HHAQ-107 instrument, PC-compatible data logging program on mini-disc, USB cable, AC adaptor, soft pouch, (6) 'AAA' batteries, and operator's manual. Replacement parts include MN2400 replacement 'AAA' batteries (2 per pack, 3 packs needed).

Key Product Differences

The HHAQ-107 is the sole model in this series bundle. The device features a dual-readout LCD display and includes an automated VOC zero adjustment procedure to maintain sensor baseline.
