Accurate temperature control - with 12V square connector probe

A 12V probe transmits temperature feedback through a square connector matched to common Chinese diesel air heater controllers. The sensor converts thermal changes into a signal that the heater regulator uses to adjust burn rate.

Precise readings keep cabin temperatures consistent and help the heater run more efficiently during cold starts.

Hassle-free fitment - with plug-and-play square connector and 30cm lead

A pre-wired 30cm lead and square connector allow direct replacement of compatible heater probes without cutting or splicing. Connector alignment matches OE-style sockets used on many diesel air heaters.

Durable performance in wet conditions - with heavy-duty waterproof construction

Sealed materials and robust construction resist moisture and road spray to protect internal sensing elements. The design minimises ingress and corrosion risks that commonly shorten probe life.

Longer service life in harsh environments means fewer replacements and more reliable heating on the move.
