The Graflex ZHS-II Heating System, originally developed as a zoom lens heater, is used to overcome low temperatures in less than desirable environments and may be applied to any device, sensor, lens, etc. The goal of the ZHS-II is meant to increase the temperature level equal to or greater than the design operating (low) temperature of said device.  The ZHS-II includes a thermostat PCB (ZM-TCB-001), one to three heater PCB’s (of up to 15 watts each), and an optional programming board. Graflex will set the heater PCB(s) to a desired wattage or the customer may set the wattage using the Programming PCB (ZM-TPB-001); the Programming PCB includes a GUI insuring easy, quick, and accurate calibration.
