The AFZ5PVBIADALHD is a 2.47 cu.ft. all-freezer with a temperature range of -30°C to -10°C as recommended for a variety of vaccines and pharmaceuticals. It is designed for freestanding or recessed installation and sized just under 32"" high to fit under lower counters complying with ADA guidelines for accessibility. The microprocessor temperature controller is externally located to minimize door openings, helping to protect stored contents from ambient temperature. The buffered temperature probe is encased in a glycol-filled bottle to better simulate temperature of the stored product, with an additional sensor that reads air temperature to ensure superior temperature control. The current and min/max temperature display is viewable in Celsius or Fahrenheit to the nearest tenth of a degree. The audible and visual temperature alarm sounds if the unit's interior goes out of range. Additional alarms include a power failure alert, door open alarm, and sensor failure alarm.
