The series 1520 is the new generation in microprocessor-based gas detection systems emphasizing simplicity of operation and reliability. It was clearly designed with the end user in mind. High and low visual alarm status is provided at the controller.
Programmable relays offer added flexibility in area monitoring.
Discrete relays for high and low alarm levels are included in the same enclosure. Push-button switches enable the user to address various setup parameters on the front panel to easily program the channel. Does not drift - no auto zeroing or adjustments required. Maintains calibration for over six months - good practice dictates calibration be checked monthly. Not saturated by occasional high concentrations of gas in the work environment.
