Microclimate Pulse B2 Thermostat Black 600w

The Microclimate Pulse B2 Black 600W is a pulse proportional thermostat built for reptile keepers who need reliable, accurate temperature control over non-light-emitting heat sources in their vivarium. Using microprocessor-driven pulse technology, it delivers precise heat management without the instability of simple on/off switching — making it a dependable choice for ceramic heaters, heat mats, and cable heaters up to 600W.

How Pulse Proportional Control Works

Rather than switching a heater fully on or off, a pulse thermostat modulates the power supplied to the heat source in rapid pulses. This maintains a far more stable temperature inside the vivarium than traditional on/off thermostats. It is important to note that pulse thermostats are not compatible with light-emitting heat sources — the pulsed power delivery will cause bulbs to flash visibly, which is why the B2 should only be used with non-light-emitting heaters.

Design Details

The temperature control dial is recessed into the casing rather than protruding outward, reducing the risk of accidental adjustment if the unit is knocked. A yellow LED indicator provides real-time feedback on how much power is currently being delivered to the heater, giving you a clear at-a-glance read on thermostat activity. The external fuse socket allows quick and straightforward fuse replacement without tools.

In the Box

The Microclimate Pulse B2 Black 600W comes complete with the thermostat unit, 2.5m sensor cable, and a set of spare fuses included as standard. Long cable lengths on the unit itself are designed to accommodate a wide range of vivarium setups without awkward routing.

For keepers running ceramic heat emitters or other non-light-emitting heat sources, the Microclimate Pulse B2 Black 600W offers a well-engineered, practical solution with the build quality and feature set that experienced reptile keepers expect from Microclimate.
