COMET GD700-1 – Type K Thermocouple (-65 to +700 °C), Subminiature Connector

COMET GD700-1 – robust Type K thermocouple (-65 to +700 °C), duplex high-temperature glass braid insulation, Ø 2 mm, Class 1 accuracy (±1.5 °C or ±0.4 %), subminiature plug 

The COMET GD700-1 is a professional Type K thermocouple with duplex high-temperature glass braid insulation and a subminiature plug – the ideal solution for precise measurements in furnaces, burners, exhaust systems, heat treatment plants, dryers, engine test benches, laboratories, industrial processes, or anywhere temperatures up to +700 °C must be measured reliably and with long-term stability. With a measuring range of -65 to +700 °C and Class 1 accuracy according to IEC 584-2 (±1.5 °C or ±0.4 % of reading – whichever is greater), it meets the highest standards of precision and stability. The duplex insulation made of high-temperature resistant glass braid (outer diameter 2 mm) provides excellent heat resistance, mechanical strength, and flexibility – even under vibration and high temperatures.

The integrated subminiature male plug enables fast and secure connection to handheld instruments, data loggers, controllers, or multimeters. Optionally, the thermocouple is also available with various cable lengths – simply select the desired length in the configurator. Whether as a replacement probe, an extension for existing systems, or for new measurement tasks – the GD700-1 impresses with top quality, reliability, and ease of use.

The thermocouple is maintenance-free, long-term stable, and designed for demanding industrial use. The high-temperature glass braid insulation protects the wires optimally against thermal aging and mechanical stress – significantly more durable than standard insulation at medium to high temperatures. Intuitive handling: plug in the connector, start measuring. The slim design (Ø 2 mm) allows use even in narrow boreholes, tubes, or compact chambers. Whether as a single probe in the laboratory, a multi-probe setup in production, or a reference in calibration – the GD700-1 is the first choice for professionals who value accuracy and durability.
