Supported Applications
The Omega THX-700 series consists of Quick Disconnect Thermistor Probes designed for use with the heavy-duty HDX handle. These probes feature a precision 44018 linear thermistor element and are compatible with all readout instruments designed for Series 700 probes. The series supports air, immersion, penetration, and HVAC applications.
Documented application areas include:
- General Purpose Probe (THX-700-GP): Gas and liquid immersion measurements.
- Penetration Probe (THX-700-NP): Soft and semi-frozen material, soil, and sand.
- Air Probe (THX-700-AP): HVAC applications; designed to fit into duct-work, grilles, and vents with a small diameter sheath and radiation hood.
Custom assemblies are available upon request through Custom Engineering.
Operating Conditions & Performance
The THX-700 series operates within a temperature range of -50°C to 100°C (-58°F to 212°F). The probes utilize a retractable coil cord and feature an aluminum die-cast handle. Wetted parts are constructed from 304 stainless steel.
Key performance parameters include:
- Sensor Element: Precision 44018 linear thermistor.
- Operating Temperature: Up to 100°C (212°F).
- Sheath Diameter: 3.1 mm (1/8") OD for General Purpose and Penetration probes; small diameter sheath with radiation hood for Air Probe.
Configuration Options
The series offers three primary configurations distinguished by probe type, each featuring a 3-prong OTP-copper connector termination. The standard stem length is 3 m (10'). OMEGALOK® compression fittings are available as an option for permanent mounting.
- THX-700-GP-12: General Purpose Probe with a 3.1 mm (1/8") OD 304 stainless steel sheath, rated for gas and liquid immersion.
- THX-700-NP-12: Penetration Probe with a 3.1 mm (1/8") OD 304 stainless steel sheath, designed for soft materials, soil, and sand.
- THX-700-AP-12: Air Probe featuring a small diameter sheath and radiation hood for HVAC duct-work, grilles, and vents.
The model number guide follows the format THX-700-<TYPE>-12. Series 700 probes are available in many other configurations beyond these standard variants.
Key Product Differences
Variations within the THX-700 series are defined by the probe tip geometry and intended media interface:
- General Purpose vs. Penetration: Both utilize a 3.1 mm (1/8") OD sheath, but the General Purpose model is specified for gas and liquid immersion, while the Penetration model targets soft solids like soil and sand.
- Air Probe Distinction: The Air configuration differs by incorporating a radiation hood and a small diameter sheath optimized for airflow measurement in HVAC systems rather than direct material penetration or deep immersion.
