ENERAC's SENSORPACK+ MODULES offer continous monitoring of Carbon Monoxide (CO), Nitric Oxide (NO), Oxygen (O₂), or Sulfur Dioxide (SO₂). They consist of a standard electrochemical cell sandwiched between an amplifier board and a diffusion cap. The amplifier board displays the gas concentration on a small LCD display.

Modules can be powered externally from a 4-60 VDC supply, or on-board lithium coin battery. The module is also compatible with bus-powered, "4-20mA Loop" systems.
The diffusion cap allows for both ambient monitoring and, with the addition of a pump, remote monitoring. The electrochemical cell has a typical life span of two years, and can be easily replaced. Miniature switches allow easy zeroing and span calibration of the module.

• For CO, NO, or SO₂, the sensor range is 0 - 2000 PPM.
• For O₂, the range is 0 - 25 %.
• For Continuous Monitoring
• Battery Powered or Externally Powered (5V-60V)
• 0.5" LCD readout
• Digital & Analog Outputs
• Compatible with 4-20mA Loop Systems
