Temp Guard Multi-Sensor watches up to three batteries and sounds a loud alarm at the first sign of
abnormal heat, even when the main unit sits elsewhere.
Most setups have more than one battery, and they're not always in the same place. Multi-Sensor comes
with two battery sensors, with a port for a third, so each battery gets its own watch.
It also includes the remote ambient sensor, for when the main unit has to sit somewhere warmer or cooler
than the batteries. The classic case is a 4WD dual battery setup, with the starting battery under the bonnet
and a second battery in the back. An engine bay gets hot and wet, so the main unit goes in the cabin and
the sealed remote ambient sensor goes by the hotter battery. Temp Guard then compares each battery
with the air it actually sits in, not the air-conditioned cabin, which helps avoid false alarms.
Sleep through the night
Temp Guard watches every battery around the clock, so you don't have to lie awake wondering about the
one you can't see.
When protection fails, Temp Guard is still watching. Your lithium battery has a BMS, and your charger
has its own protection. Most of the time they quietly do their job. But protection can fail. A cell fails, the
charger keeps charging and the BMS doesn't trip. And because batteries usually live out of sight, you
might not know anything is wrong until it's too late. That's why we built Temp Guard to work on its own,
with its own sensors and its own power.
It checks three things at once: how hot each battery is, how fast it's heating, and how much hotter it is than
the air around it. A fast temperature rise is a recognised warning sign of thermal runaway, and Temp Guard
is built to catch it. The moment something isn't right, it sounds a loud alarm and lights up, giving you time
to switch off, get everyone clear and call emergency services if you need them. Early warning is time, and
time is what keeps people safe. It could save your life.

Catches trouble early
Alarm points are set at the factory: WARNING 55 °C, CRITICAL 60 °C and RAPID EVENT 70 °C, with
matching alarms for fast heating and for heat well above the surrounding air. Nothing to set, nothing to get
wrong.
Keeps going when everything else stops
It runs on its own three AAA batteries, so it keeps watching even if your battery system or BMS shuts
down.
No off switch, on purpose
A safety device only protects you while it's on. So Temp Guard is always on. It can't be bumped off or
forgotten after a trip.
Clear lights, loud alarm
STATUS, FAULT, WARNING and CRITICAL lights tell you exactly what's happening the moment the
alarm sounds.
Fits any battery
Designed for lithium, works on any battery type. It only measures temperature, and the sensors are
electrically isolated, so you can fit one to any battery in a bank, even a 24 V series bank.
Looks after itself
The AAA batteries last up to 12 months with one sensor in normal use. Temp Guard tells you when they're
getting low or a sensor has a fault, and a built-in watchdog restarts it if anything ever glitches.
Fit it once. Test it. Then get on with your trip. We've done the hard work to keep you safe.
Built to watch what you can't. Designed by Durst Industries Australia and backed by a 3-year Durst
warranty.
