Airflow monitors

Since 2003, we’ve supplied more than 60,000 TEL airflow monitors that have since been installed on fume hoods and biological safety cabinets throughout research centres, universities and laboratories in North America.

Real Benefits:

Safety and compliance

These innovative monitors are designed to ensure the safety of your staff, and compliance to legislation.

Reliable

With no inherent drift, airflow sensors will measure face or duct velocity accurately for many years without needing recalibration.

Easy

We can generally install and calibrate most TEL monitors in an hour or less.

Flexible

We supply to both fume hood manufacturers and laboratory managers who wish to add a monitor to an existing hood.

Bio-Safety cabinet monitors
LEV

A local exhaust ventilation (LEV) monitor will provide you with reassurance that your system is maintaining flow-rate. If flow-rate falls, this monitor will alert operators immediately, ensuring your employees are safe. It can be fitted to ducting or an LEV extraction device for peace of mind.

XPA

Intended for use in laboratories classified as a hazardous location, this “explosion-proof” alarm continuously monitors the negative static pressure in a fume hood exhaust duct.  All electrical housings are UL or FM approved for Class 1, Div 1, Groups B, C and D. Two buzzer options are available — Class 1, Div 2 or Class 1, Div 1. Customers should specify which buzzer when requesting a quote.
