The factory setpoint for R12 is 500 ppm while the setpoint for R134a is 50 ppm. See the specifications for more details. Temperature Range The Model 2050 and 2060 have temperature compensated circuitry to provide stabilization in temperatures ranging from -4o to 158oF. Semiconductor-Type Sensor A solid-state semiconductor-type sensor and associated electronic circuitry ensure trouble-free, long-term operation. There are no pumps, filters, or chemical cells to replace or maintain. Except periodic calibration to verify the alarm setting, no periodic maintenance is required after installation. The user may adjust the alarm level by using a different calibration gas concentration.
