APEX Premier |
|||||||||||||||||||||||||||||
|
The Apex Premier™ utilizes state-of-the-art technology to provide the highest level of performance achievable in a fume hood monitor. The heart of the Apex Premier is the smart sensor module which is responsible for accurate, repeatable and instantaneous measurement of fume hood face velocity. Face velocity measurement is made by an ultra-sensitive micro-bridge mass airflow sensor with a response time of less than 3 milliseconds. The analog signal provided by the micro-bridge is digitized by a high-resolution A/D converter, then further enhanced and factory calibrated over the operating velocity range by an automated test an calibration system. |

APEX
BASIC |
|||||||||||||||||||||||||||||
|
Tek-Air is proud to introduce the APEX Basic Velocity Alarm to the Critical Environments Industry. The APEX Basic was developed by Tek-Air to provide the industry with a cost-effective, accurate and reliable velocity alarm to help ensure a safe operating environment for laboratory personnel. The APEX Basic is suited for use on all types of fume hoods and Biological Safety Cabinets. |

Accuvalvetm |
|||||||||||||||||||||||||||||
|
The AccuValve™ AV2000 airflow control valve is a revolutionary product in which Computational Fluid Dynamics (CFD)
was utilized to aid in its design. This resulted in a valve that maximizes turndown while maintaining high accuracy
throughout the flow range. The AV2000 is the first truly new design in airflow control valves in decades. |

FVC-2100/2200 |
|||||||||||||||||||||||||||||
|
For basic constant velocity fume hood control using face velocity measurement, Tek-Air recommends model FVC-2100 or FVC-2200. The two systems utilize identical components with the exception of duct exhaust volume sensing equipment added to the FVC-2000 to provide flow limit control. Tek-Air's VorTek airflow traverse probes provide volumetric measurement in that application.
Both systems provide face velocity control using
the "sidewall sensing" method. The basic system consists
of a controller, sensor probes, display unit, I/P converter, and exhaust
air control valve. The controller is typically wall-mounted above
the fume hood. The thermal face velocity sensor in the controller
connects via PVC tubing to the hood probe mounted on the inner sidewall
of the fume hood and the reference probe mounted outside the fume hood
interior. |

IAQ2000 |
|||||||||||||||||||||||||||||
|
The IAQ Outdoor Air Measurement system is designed for accurate measurement in outdoor air inlet situations where low velocity,
dirt, moisture and turbulence affect other products in quantifying the volume of fresh air to the building. The IAQ utilizes a Patented
air flow sensor in conjunction with a transducer and monitor assembly, which incorporates intuitive directions for the user in setting up
and maintaining the product. |

The PVT-2000 is a precision airflow control valve consisting of a Vortek
VT-2000 airflow measuring device mounted in the inlet of a PRD airflow
control valve. A factory-installed current-to-pressure (I/P at 4-20
ma) or voltage-to-pressure (E/P at 2-10 vdc) transducer takes an electronic
control signal from any airflow controller to modulate the PRD. The Vortek
transmitter provides a |

Iso-tek spm-2000 |
|||||||||||||||||||||||||||||
|
The Iso-Tek space pressurization monitoring system is designed for use in a wide variety of applications that necessitate the monitoring of airflow from one room to another. The monitor system can be configured by the user for bi-directional measurement of either air velocity in feet per minute (fpm), or air pressure in inches of water column ("wc"). |

TFP-5000 |
|||||||||||||||||||||||||||||
|
The TFP-5000 Airflow Measurement Probes have an extremely low YAW angle effect throughout the 30° range, an improved signal-to-noise ratio, and they generate an amplified differential pressure signal, improving the ability to make low velocity measurements. Insertion Probes can easily be installed in either new or existing ductwork by cutting small entry holes in either side and installing the sensors across the duct area. Where the sensor must be removed for periodic inspection or cleaning, insertion probes provide an excellent measurement solution. The TFP-5000 probes are manufactured in one-inch increments in lengths from four to 146 inches long, for rectangular, circular, and oval ductwork. Achievable accuracies are typically within 2% of actual airflow. |

VT-2000 |
|||||||||||||||||||||||||||||
|
The VT-2000 Airflow Measurement Probe consists of multi-sensor probes available as insertion probes or in pre-assembled airflow stations. Individual sensors provide frequency pulse outputs which are directly proportional and linear to airflow velocity. These digital signals are totalized in the companion transmitter and are converted to a 4-20mA, 1-5 or 2-10 VDC output, linear to flow. Units are available with one to four sensors, in sizes as small as 4" diameter up to four square feet. Either 24 VAC or 15 to 35 VDC power is required for operation. |

VT-5000 |

|
Velocity measurement is accomplished by Tek-Air's unique, patented, VorTek sensors. VorTek sensors utilize proven vortex shedding phenomena to measure the true airflow velocity independent of changes in temperature, density, and humidity which affect Pitot and thermal airflow measurement systems. The VT-5000 Airflow Measurement Probe consists of multi-sensor probes inserted in the ductwork where airflow is to be measured and transmitted. Individual sensors on the probes provide pulse frequency electronic output signals which are directly proportional and linear to the airflow velocity. These signals are totalized in the companion transmitter and converted to an industry standard, 4-20mA output. (1-5 VDC or 2-10 VDC are also selectable by jumper). |
