COMET T0310 - RS232 Temperature Transmitter -30 to +80 °C

COMET T0310 – robust, waterproof temperature transmitter with internal sensor 

The COMET T0310 is a classic, extremely durable temperature transmitter with an integrated high-precision sensor for versatile indoor and outdoor use. Whether in production halls, warehouses, server rooms, greenhouses, on rooftops, or in building management systems – thanks to its fully waterproof IP65 housing and measuring range from –30 to +80 °C, it delivers reliable performance for years under normal environmental conditions.

The RS232 interface with Modbus RTU protocol (compatible with Advantech ADAM) allows easy integration into control and monitoring systems. The large, high-contrast dual-line LCD clearly displays the current temperature in °C or °F and can be completely switched off during continuous operation to save power.

State-of-the-art digital technology ensures outstanding long-term stability and automatic fault detection – the T0310 reliably reports sensor issues. With a weight of only 140 g and a compact design (88.5 × 148 × 39.5 mm, probe length 53 mm), the T0310 can be easily installed anywhere – on walls, poles, or directly in control cabinets.

For years, the T0310 has been the proven standard for accurate temperature measurement in demanding environments.
