Fume Hood Monitors
Alnor AirGard® 200 Fume Hood MonitorPrice - $335 The AirGard 200 continuously monitors fume hood face velocity by measuring the air velocity of clean air from the room passing through the air inlet on the front of the monitor. This simple, go/no-go alarm is a low cost option for your monitoring requirements. It is an easy to install flush mount monitor that only requires a single point calibration in the field. The device provides both visual and audible alarms to alert the user of abnormal airflow conditions. A green indicator on the front of the monitor indicates normal flow conditions. When flow conditions lower than the setpoint are encountered, a red indicator is activated along with an audible horn. This information can be sent to a remote location by means of a dry contact relay output. |

Alnor AirGard® 335 Fume Hood MonitorPrice - $495
The AirGard 335 continuously monitors fume hood face velocity by measuring the air velocity of clean air from the room passing through the air inlet on the front of the monitor. The monitor then reports this information through readily understandable means to the user. An electronic bargraph moves back and forth through universally recognized red (danger), yellow (caution) and green (safe) colored zones as the velocity changes. Corresponding large colored lights also illuminate. A continuous audible alarm alerts of a dangerous situation when the face velocity is in an alarm condition. This information can be sent to other personnel in a remote location by means of a dry contact relay output. A digital display can be enabled to view velocity quantitatively. The monitor mounts flush to the fume hood surface and fits into a single electrical receptacle box knock-out. |

Alnor AirGard® 385 Fume Hood MonitorPrice - $495
The AirGard 385 continuously monitors fume hood face velocity by measuring the air velocity of clean air from the room passing through the air inlet on the front of the monitor. The unit then reports this information visually through a digital display and colored lights, as well as with a continuous audible alarm when the face velocity is in an alarm condition. This information can be sent to a remote location by means of a dry contact relay output and 0-4 volt analog output. The monitor mounts flush to the fume hood surface and fits into a single electrical receptacle box knock-out. |

Alnor AirGard® 480 Fume Hood MonitorPrice - $625 The AirGard 480 continuously monitors fume hood face
velocity by measuring the air velocity of clean air from the room passing through the air
inlet on the front of the monitor. The face velocity is displayed numerically, but the
monitor also features an LED column of lights to show air flow trends. The instrument is
flush mounted to the surface of the fume hood. It provides visual, audible, and remote
alarms for abnormal air flow conditions. This information can be sent to a remote location
by means of a dry contact relay output and 0-5 volt analog output. It can also print and
store air flow measurements at periodic intervals through the communications port when
connnected to a personal computer. |
