he VE-300 has the added benefit of battery backup and several alarm options that alert you to errors, including the sensor failure alarm (which sounds when the probe fails), the temperature overshoot alarm (sounds when the set temperature is exceeded by at least 4 degrees), and the too long to setpoint alarm (which alerts the user when the heating device fails). The unit also has a built-in night drop feature, which allows for a regular temperature drops to be set at night.

The VE-300 features include

  • Convenient tabletop mounting
  • Full back-lit display
  • Displays probe temp and set point on the main display
  • Hi/Lo History for each zone
  • Hi/Lo Alarms for each zone
  • Battery backup for clock
  • Built-in Night Drop capability for each zone (independent)
  • Remembers settings during power failure
  • Built in Safety Shutoff relay
  • Grounded receptacle
  • 900 watt total capacity with user replaceable fuse (Spare fuse included!)
  • 10′ probe cords (2)- user-replaceable
  • 6′ Power cord
  • Multiple units can be stacked
  • Pulse Proportional OR On/Off capable for each zone

The standard display shows the current setpoint value, the current time of day, and the current probe temperature reading.  3 button keyboard makes it easy to navigate the menu and the large back-lit display makes programming easy.  The VE-300X2 adds the additional feature of two independent thermostats in one unit

Both the probes and fuse are easy to replace.  The probe cord locks in place to prevent accidental disconnection.  Comes with a 6′ power cord and two probes.


A thermostat works just like the thermostat in your home.
It keeps the heat in your tubs at a pre-set temperature. If you had no thermostat on your home heating system you would bake yourself and burn out the heating element much faster.

There are 2 different types of thermostats.

  1. On/off thermostat. This type lets the heat tape get to just above the set temp then shuts off. When the temp of the heat tape falls below the set temp the thermostat will send power to the heat tape until it heats up again.
  2. Proportional. This type sends small pulses to the heat tape to keep the temp a bit more steady( which is not as crucial for rack systems but you should definitely use a proportional thermostat for incubators)

All thermostats do the same thing, control the heat.
Some have more options we like to call “bells and whistles”. They are not required but some people like them. Examples are Hi/Lo alarms, night drop, etc.

A thermostat must be used to control the heat in our rack (or any rack system).
You can use one thermostat for multiple of the same rack system (up to the wattage capacity of the thermostat) but not for 2 different rack systems (unless the thermostat has 2 or more probes like the Vivarium VE 300 X2). For example, you run up to 6 of our sub-adult racks safely on one Vivarium VE 200 (700 watt capacity) since our sub-adult rack uses approximately 100 watts per rack. But you should not run a Vivarium Ve 200 for 2 of our sub adult racks and 2 V70 racks as the tub characteristics are different and they also use different wattage heat tape. But The Vivarium VE 300 X2 has 2 probes and therefore can run 2 different rack systems.
