COMET GD700-1/0 – Type K thermocouple (-65 to +700 °C), without connector

COMET GD700-1/0 – 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 %), without connector

The COMET GD700-1/0 is the professional Type K thermocouple without connector with duplex high-temperature glass braid insulation – the ideal solution for precise high-temperature measurements in furnaces, burners, exhaust systems, heat treatment plants, melting furnaces, 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 requirements for precision and stability. The duplex insulation made of high-temperature resistant glass braid (outer diameter 2 mm) offers excellent heat resistance, flexibility, and mechanical protection – ideal for applications with vibrations, high temperatures, and moderate mechanical stress.

Without integrated connector – ideal for custom wiring, direct connection to terminals, controllers, loggers, or customer-specific connections. Optionally, the thermocouple is available with various cable lengths – simply select the desired length in the configurator. Whether as an open wire probe for special installations, replacement in existing systems, or for new measurement tasks – the GD700-1/0 impresses with top quality, reliability, and mounting flexibility.

The thermocouple is maintenance-free, long-term stable, and designed for demanding industrial use. The high-temperature resistant glass braid protects the wires optimally against thermal aging and mechanical stress – significantly more durable than simple insulations at medium to high temperatures. Intuitive handling: install or connect the probe, connect the bare ends, 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, multi-probe in production, or reference in calibration – the GD700-1/0 is the first choice for professionals who rely on accuracy and durability.
