Thermo Probe

Founded in the early 1990s in the United States, ThermoProbe, Inc.® has established itself as a premier global specialist in the design and manufacture of intrinsically safe, portable digital thermometers. By focusing on high-precision temperature measurement for hazardous environments, the brand has become the industry standard for safety and accuracy in the Petrochemical and industrial sectors. As the authorised Australian partner, we provide local refineries, tank farms, and inspection agencies with direct access to these robust instruments, which are essential for critical workflows across Australia and New Zealand.

ThermoProbe engineering is defined by a commitment to rugged reliability and traceable accuracy, ensuring that every reading is dependable even in the most demanding field conditions. Their instruments are specifically designed to replace traditional mercury-in-glass thermometers, eliminating environmental hazards while providing modern features such as Min/Max/Avg logging and stability indicators. We support these advanced Measuring and observing and testing instruments with factory-trained technical support and local technical guidance to ensure your facility maintains the highest standards of analytical integrity and safety compliance.

Technical Applications for ThermoProbe in Australia

In the Australian petroleum and chemical industries, achieving repeatable and safe temperature measurement during custody transfer and inventory control is a primary technical priority. The range of specialised gauging thermometers includes the Thermo Probe TP7-D 25 Meter Thermometer, which features a spool-reel design for quick deployment in large storage tanks. For high-viscosity products like bitumen or heavy crude, the TP7-D with Asphalt Weight Probe ensures that the sensor reaches the required depth for a representative sample.

For more specific field inspection needs, we offer multiple configurations such as the TP7-D with Extra Weight Probe for stable measurement in moving liquids, and versions with Metric Brass Markers for precise depth verification. Laboratories requiring high-precision reference measurements can also benefit from the TL series, which provides a safe and mercury-free alternative for calibration and distillation tasks. By integrating these robust ThermoProbe solutions into your workflow, we help Australian facilities achieve scientific precision while adhering to strict international safety standards for hazardous locations.

Why Source ThermoProbe from John Morris Group?

• Intrinsically Safe Certification: Instruments are certified to the latest international standards (ATEX, IECEx, and TR TS) for use in Zone 0 flammable conditions, providing ultimate peace of mind in explosive environments.
• Rugged Spool-Reel Design: The TP series features a unique spool design that allows for rapid deployment and retrieval of the sensor probe, reducing operator exposure and streamlining tank gauging.
• High-Accuracy RTD Technology: Utilises proven thin-film RTD sensors to provide stable, long-term accuracy and rapid response times across a wide temperature range of -40°C to 204°C.
• Glove-Friendly User Interface: Large 1/2-inch alphanumeric displays and raised, rugged buttons are specifically designed for ease of use by technicians wearing safety gloves in the field.
• Mercury-Free Laboratory Safety: The TL series provides a high-precision digital replacement for hazardous glass thermometers, eliminating the risk of mercury spills in pharmaceutical and food labs.

We back this world-leading range with over 70 years of local experience, providing Australian and New Zealand customers with factory-trained service, NIST-traceable calibration, and dedicated application support through our regional service centres.

Frequently Asked Questions

What does "Intrinsically Safe" mean for these thermometers?
Intrinsically safe (IS) means the device is designed with limited electrical and thermal energy, so it cannot cause the ignition of a specific hazardous atmospheric mixture. This makes ThermoProbe units safe for use in explosive environments like fuel tanks and refineries.

Which probe weight should I choose for my application?
Standard weight probes (0.25 lb) are suitable for most light petroleum products. Extra weight probes (0.50 lb) are better for higher-viscosity liquids or where wind/flow may displace the probe. Asphalt weight probes (0.75 lb) are specifically designed to sink through very thick or viscous materials like molten sulphur or bitumen.

How often should a ThermoProbe unit be calibrated?
To maintain technical accuracy and satisfy regulatory requirements (such as API 7.2), it is recommended to have your unit calibrated annually. We provide NIST-traceable calibration services that include a 4-point report to ensure your instrument remains within specified tolerances.

Can these thermometers be used for bitumen and asphalt?
Yes, the TP7-D and TP9-A series are frequently used in the asphalt industry. We recommend selecting a model with an "Asphalt Weight" probe and non-stick cable to ensure easy cleanup and accurate immersion in hot, viscous materials.

What is the typical battery life of a portable ThermoProbe?
Most models, including the TP7-D, are powered by two standard AA alkaline batteries that provide approximately 200 hours of continuous operation. The units include a low-battery indicator and an auto-off feature to preserve power when not in use.

Where can I get my ThermoProbe instrument serviced in Australia?
John Morris Group provides full local support, including repair, probe replacement, and calibration through our service centres in Australia and New Zealand. Our factory-trained technicians ensure your safety-critical measurement tools are maintained to original manufacturer standards.
