Fisher Scientific Isotemp 725F Oven
The Fisher Scientific Isotemp 725F Oven is a forced air oven designed to provide improved temperature uniformity and control, as well as faster drying. Fresh air enters through an air intake on the bottom of the oven, then is heated in a plenum below the chamber with a range from 50°C to 275°C. Temperature readouts and control parameters are shown on red LEDs. Three additional LEDs indicate when heater power is being applied, an error condition is encountered, or the temperature is being set. The Fisher Scientific Isotemp 725F Oven also incorporates a variety of safety features. A safety backup is built into the controller software: if the primary heater control fails, the backup will maintain control at 5°C above the set point. An alarm LED then indicates that the backup controller is operating the oven. A circuit breaker protects the oven from power surges.
All of our equipment will be fully tested to perform at factory specifications before being shipped.
The Fisher Scientific Isotemp 725F Oven includes:
- 1 Shelf
- Power Cord
- Operator's Manual
- Full 180 Day Parts and Labor Warranty
