COV-2

Product catalog summary
Overview: The VOC-2 is a Volatile Organic Compounds Detector designed to monitor and control indoor air quality by detecting gases such as toluene, hexane, benzene, and xylene. It is particularly useful in addressing "Sick Building Syndrome" by ensuring effective ventilation and alerting users to elevated pollutant levels.
Features:
  • Fully electronic system with solid-state circuitry and built-in sensor.
  • Compact, corrosion-resistant gasketed enclosure.
  • Two factory-calibrated operating levels (Low & High) with visual indicators.
  • Audible alarm for high-level detection.
  • High sensitivity, stability, and temperature compensation.
  • High long-term reliability and can be mounted on a wall or column.
Technical Specifications:
  • Sensor: N-type Metal Oxide Semiconductor (MOS).
  • Mounting: Wall or column with supplied brackets.
  • Dimensions: 152mmH x 152mmW x 101mmD (6”H x 6”W x 4”D).
  • Supply Voltage: 120V AC (also available in 24 or 220V AC).
  • Ambient Temperature: 10-40º C (50-100º F).
  • Contact Rating: 5A @ 120V AC 1PH.
  • LED Indicators: Power On, Low Level, High Level.
Principle of Operation: The VOC-2 uses a tin dioxide semiconductor gas sensor to detect VOCs. The sensor's electrical resistance decreases when exposed to gases, providing an output signal for detection. It features two operating levels: Low (activates a SPDT relay contact) and High (activates another SPDT relay contact and an audible alarm). Temperature variations are compensated by a thermistor in the detection circuit.
Installation and Maintenance: The VOC-2 requires a 120V AC power supply and should be installed at specified locations. It includes visual indicators for power and operating status, and an integral audible alarm for high-level detection. The unit's enclosure is made of corrosion-resistant material and is gasketed for protection.
Additional Information: The VOC-2 is part of a broader range of VOC detection solutions, with options for pneumatic sampling and alternate contact levels available upon request. For further details, contact ACME Engineering Prod. Ltd. in Canada or ACME Engineering Prod. Inc. in the U.S.A.

VOC-2 : Volatile Organic Compounds Detector VOLATILE ORGANIC COMPOUNDS DETECTOR WITH TWO CONTACT LEVELS Features: Fully electronic system with solid state circuitry and built-in sensor. Suitable for ventilation control. Audible alarm. Compactcorrosion resistant gasketed enclosure. Two factory calibrated operating levels (Low & High) with visual indicators. Indoor air quality problems, known as "Sick Building Syndrome" have become issues of health and comfort in new and recently remodeled buildings. Buildings are called "Sick" when their occupants experience symptoms such as headaches; eye, nose and throat irritation; dizziness; nausea; sensitivity to odors; and difficulty in concentrating. Frequently encountered IAQ problems are caused by elevated indoor pollutants such as VOCs (Volatile Organic Compounds) and ineffective ventilation systems in buildings. High sensitivity stability. Temperature compensated. High long-term reliability. Can be mounted on a wall or on a column. VOC emanations (such as toluene), are released by synthetic materials, cleaners, printers, paints, etc. Once the VOC-2 detects concentrations in excess of calibrated levels, it demands ventilation and/or signals an audible alarm. The VOC-2 can be installed in stagnant areas of buildings where pollutant concentrations will rise. Standard units are calibrated using toluene. Units can also be calibrated with other compounds specified by the customer.
