The TP7-D is a Zone 0 intrinsically safe digital gauging thermometer re-designed to the latest
standards for use in hazardous locations. With over 30 years experience manufacturing digital thermometers, ThermoProbe has designed the
TP7-D with reliable RTD sensors based on our previous industry-standard thermometers such as the TP7-C and TP9.
Based on our laboratory thermometer technology, the latest TP7-D electronics are more accurate than
previous models. The convenient user interface provides a large 1/2” alpha-numeric character display and buttons that can be easily used
with gloves. An automatic backlight feature is included to help read the display in low light conditions. An intuitive menu allows the
user to easily select Celsius or Fahrenheit units, display resolution, and access calibration. Icons on the display help the user
identify temperature stability, battery condition and menu items. The TP7-D comes equipped with easily replaceable AA batteries,
providing up to 200 hours of operation.
The TP7-D rugged instrument body is constructed from stainless steel and static-dissipative plastic
components. The TP7-D spool-reel design allows the user to quickly deploy and retrieve the sensor probe into various products. With
multiple probe configurations and allowable lengths up to 50 meters (165 ft), the TP7-D is well suited to many tank gauging
applications. The probe assembly is constructed of easy to clean materials such as non-stick cable and stainless steel.
Thermoprobe gauging thermometers come equipped with probe assemblies consisting of a length of non-stick 2-wire cable and a stainless
steel weighted RTD temperature sensor. Indelible brass markings are applied to the cable to aid in tank depth determination. The Probe
Assembly part numbers are specified as follows:
Example: Our most standard PG-075-SW-SM probe assembly is 75 feet long (075) with a Standard Weight (SW) and
brass markings every 5 feet (SM). Various configurations are available.
0.25 lb (0.11 kg)
This reliable design is our most popular probe.
0.50 lb (0.23 kg)
This design has the same diameter as the Standard Weight but is slightly longer and heavier.
Railcar Weight / No Weight
The Railcar probe is produced as a specialty probe for the railcar industry specifically for small diameter gauging tubes fitted
in many tanker cars.
0.75 lb (0.34 kg)
The probe of choice when working with liquid asphalt, molten sulfur, molasses, or similar high-viscosity petrochemicals.
The TP7-D is recognized with international (IECEx), European (ATEX), and EurAsian (TR TS) safety
