COMMON QUESTIONS

Every three months at a minimum. Monthly calibration is recommended, especially for lower range/more critical applications.

Our ECS (Electronic Calibration Service) is offered for those customers who find it inconvenient to obtain their own calibration standard.

10-20 grams/month.

A weight loss of more than 50 grams makes sensor restoration difficult, and beyond 100 grams, it is virtually impossible. Weight loss is affected by ambient humidity, flow rate, and in certain cases, the type of sensor being used.

The sensors work best, and last longer, if they are kept moist. If your sensor is losing more than 50 grams of water per month, add water every two weeks.

Please refer to the detailed information provided in our Interfering Gas Data tables. For items not given in these tables, contact the service department.

Typical sensor life is 2-3 years. This assumes proper maintenance, and infrequent exposure to concentrations well above the intended measuring range of the instrument.

Dispose of an old sensor the same way you would dispose of an old car battery. Facilities exist in most communities to handle this type of waste.

Yes. We do this to serve you better and more efficiently. Please request an RMA form here.

Your EtO monitoring system is very sensitive, and must respond to sub parts-per-million (ppm) concentrations of this gas. It may be that maintenance crews are using floor wax, strippers, assorted cleaning products, or isopropyl alcohol, and these compounds can cause a response on the system, especially since they would be present at concentrations in excess of 500 ppm.

The sampling pump(s) of the system should be shut down temporarily during these maintenance operations, to avoid false alarms. A special timer, that re-starts the sampling pump(s) after a customer-adjustable time interval, is available to perform this action automatically.

Do not attempt to remove these interferences by covering the sample inlet with a rag or other obstruction, as this can clog up the sample inlet, thus causing the pump to pull its full vacuum on the sensor—leading to irreversible sensor damage.

This scrubber material comes in purple pellets, that will turn dark brown or black with use. The scrubber should be replaced when the majority of the pellets in the tube have turned color.

Most orders for sensors and parts can be shipped within two days. If you have a super-rush situation, please notify us! An expedite fee will apply to specially expedited/rush orders.
