Proportional heating constantly monitors and adjusts amount of heat necessary to maintain a target temperature (Usable range from 50°F to 140°F or 10°C to 60°C). Can also be used in non-proportional (on / off) mode · Night Drop capability when used with optional cable · Precision Sensor with internal resolution of .1125 °F and is accurate to ± .9 °F · Allows display and setting in tenths of a degree · Sensor Matching allows the user to digitally calibrate the sensor output to match other equipment · Power Matching allows the user to increase / decrease the proportional power output curve to match the enclosures efficiency. · Cooling function allows Herpstat to control basic cooling devices · High / Low temperature tracking helps monitor heating system and enclosure efficiency · All settings are retained in memory even if power is lost · Temperature can be set / displayed in Fahrenheit or Celsius · Easy to read 3 digit LED display with heat output indicator · Removable sensor allows for easy replacement if necessary · Easily mounts to enclosures with built in hanger · Internal error detection shuts off heat if sensor fails or is disconnected · 500 Watt output sufficient for most incubators, rack systems, enclosures, and vivariums · 1 year limited warranty
