"Easy Cal" Sensor just made calibration easier.

"Easy Cal" Calibrates in 2 Minutes

The new sensor incorporates a microprocessor which makes the calibration process, both span and zero simpler and faster than with the current standard sensors.  The user simply presses a button when the calibration gas is applied rather than adjusting a potentiometer as in the standard sensor design.  It could not be easier.

User Calibration Method

1. Either blank or apply required zero gas/air to sensor.

2. Hold down button until LED flashes at approximately 1 Hz. (zero level now  set).

3. Apply required span gas to sensor for 2 minutes.

4. Press and release button (span level now set).

5. There will be an 8-second time-out period and flashing LED approximately 8 Hz.

6. Calibration is complete, LED clears and returns to normal mode.

Sensors Available:  Chlorine, Hydrogen Sulphide, Sulphur Dioxide, Hydrogen, Nitrogen Dioxide and Carbon Monoxide.
